QSFP Cable and Connectors Assemblies

A quad (4-channel) Small Form-factor Pluggable Optics Transceiver is also known as a QSFP cable. For applications requiring 40 Gigabit Ethernet (40GbE) data transfers, it is a small, hot-pluggable fiber optical transceiver. They are often used for the implementation of 40G Ethernet, Infiniband, and other communications protocols in data centers.

It connects a fiber optic or copper cable to network equipment, such as a switch, router, media converter, or similar device.

In addition to copper cable media, QSFP+ optic transceivers are made to support Serial Attached SCSI, 40G Ethernet, 20G/40G Infiniband, and other fiber optic communication standards. In comparison to SFP+ optic modules, the QSFP28 cable significantly increases port density by 4x.

Optical transceivers are compact, strong devices that add fiber ports to switches or other networking equipment by connecting them to copper or fiber optic cables. Data is transmitted using optical fiber in conjunction with fiber optics in the form of light pulses that travel at very high speeds and can cover very long distances. The transceiver, which is a laser with a certain wavelength that transforms electrical signals into optical signals, is a crucial part of the fiber optic network. The data is then converted into a signal with a specific wavelength by the transceiver and sent over the optical fiber. Wideband signals are those that are 850 nm, 1310 nm, and 1550 nm in wavelength. Narrow bands are the term for CWDM or DWDM signals. Each channel is unable to interact with the others due to the special property of light.

This indicates that a network can handle the transmission of both wideband and narrowband signals. Direct attach copper (DAC), active optical cables (AOC), optical modules, and active copper cables are all types of QSFP interconnects (ACC). The least costly choice is DACs. They offer a connection that depends on host signal processing. The maximum length that can be achieved depends on the cable assembly's insertion loss, which is determined by its length and cable gauge and is guided by the IEEE specifications (see below) (AWG). The AWG of a wire has an inverse relationship with its size. AWG and wire diameter for QSFP cable assemblies are plotted in the table below.

Uses for an optical isolator

Rotators Difference between an Optical Circulator & Isolator & RotatorĪn optical circulator is used to route the incoming light signals from port 1 to port 2 in a way that if some of the emitted light is reflected back to the circulator, it doesn’t exit from port 1 but from port 3. This rotator is used for amplitude modulation of light and is an integral part of optical isolators and optical circulators. What is an optical rotator?Īn optical rotator is typically an in-line Faraday rotator that is designed to rotate the polarization of the input light by 45 degrees. This is what makes it possible to achieve higher isolation. Hence, it adds to the total of 90 degrees when light travels in the forward direction and then the same in the backward direction. It happens because of the change in the relative magnetic field direction, positive one way, and negative the other way. It means that the rotation is positive 45 degrees in the forward direction and negative 45 degrees in the reverse direction. The polarization rotation caused by the Faraday rotator always remains in the same relative direction. Its main component is the Faraday rotator which ensures non-reciprocal rotation while maintaining linear polarization. What is an optical isolator?Īlso known as an optical diode, an optical isolator is an optical passive component that allows the light to travel in only one direction. While some circulators are three-port devices, there are also four-port circulators. In short, it is designed such that the light coming from one port exits from the next port. What is an optical circulator?Īn optical circulator is a high-performance light-wave component that is designed to route the incoming light signals from Port 1 to Port 2 and the incoming light signals from Port 2 to Port 3. Circulator & Isolator & RotatorĪs we are discussing specifically optical passive components, you will learn here about optical circulators, optical isolators, and optical rotators rather than their electronic counterparts. So, if you are curious to know about these little yet important optical passive components, read the blog till the end.

Qu’est-Ce Que Le Module Émetteur-Récepteur Optique ?

La demande des utilisateurs pour les réseaux de communication croissante a favorisé le développement rapide des modules optiques. Mais qu'est-ce que le module émetteur-récepteur optique ? Quels sont les types des modules émetteur-récepteur optiques ? Comment choisissez-vous le module optique le mieux adapté à votre application parmi de nombreux modules optiques différents ? Aujourd'hui, nous allons vous donner la réponse !

Le module émetteur-récepteur optique est un dispositif qui utilise la technologie fibre optique pour envoyer et recevoir des données. Le module optique est constitué de dispositifs optoélectroniques, de circuits fonctionnels et d'interfaces optiques. Les dispositifs optoélectroniques comprennent des parties d'émission et de réception. Autrement dit, le rôle du module optique est la conversion photoélectrique, le côté émetteur du signal électrique en signaux optiques, à travers la transmission de fibre optique, le récepteur puis la conversion du signal optique en signaux électriques. Le rôle du module optique pour le basculement entre l'appareil et la transmission du transporteur, par rapport à l'émetteur-récepteur est plus efficace et fiable.

Les types des modules optiques

Le module optique, principalement divisé en GBIC, SFP, SFP +, XFP, SFF, CFP, il y a deux types d'interface optique, y compris SC et LC. Les SFP, SFP +, XFP sont plus couramment utilisés que les GBIC .

Par paquet : GBIC, SFF, SFP, XFP, SFP +, X2, XENPARK, 300pin, etc.

Selon le taux : 155 M, 622 M, 1.25 G, 2.5 G, 4.25 G, 10 G, 40 G et ainsi de suite.

Par longueur d'onde : CWDM, DWDM, etc.

Par mode : fibre monomode, fibre multimode. Le module optique mono-mode est pour une longue distance de transmission. Le module optique multi-mode est pour la transmission à courte distance.

Par utilisation : échange à chaud (GBIC, SFP, XFP, XENPAK) et échange non-chaud (1 * 9, SFF).

SFP

Le SFP, enfichable et à faible encombrement, est un module optique compact et enfichable à chaud utilisé pour toutes les applications de télécommunications et de transmission de données. Il peut être considéré comme la version améliorée du GBIC. Sa taille est seulement environ une moitié de celle du GBIC, ce qui permet d’économiniser plus d’espace. Avant l'avènement de la mise à niveau SFP, les modules optiques SFP étaient le module optique le plus répandu sur le marché. 

SFP+

Le SFP+ est une version améliorée du SFP. Il soutient un débit de données jusqu’à 10 Gbit/s, un fibre Channel de 8 Gbit/s, 10 Gigabit Ethernet et la norme OTU2 du Réseau de Transport Optique. 

XFP

Le XFP a apparu avant le SFP+. Il est un format standard pour les modules optiques de série de 10 Gb/s. Il est indépendant du protocole et complètement conforme aux normes suivantes : 10 G Ethernet, 10 G Fibre Channel, SONET OC-192, SDH STM-64 et OTN G.709, soutenant un débit binaire de 9.95 G à 11.3 G. Il est utilisé dans le lien optique de la communication des données et de télécommunication et offre un format plus petit et une consommation d’alimentation plus faible que d’autres transpondeurs de 10 Gb/s. 

QSFP/QSFP+

Le QSFP est l’abréviation de Quad (4 canaux) Small Form-factor Pluggable. Il est un module optique compact et enfichable à chaud utilisé également pour les applications de transmission de données. Par rapport au QSFP+, le QSFP soutient un quart d’un enfichable à petit facteur avec un différent débit de données, ce qui ne change rien à la solution du produit. Aujourd’hui, le QSFP+ remplace graduellement le QSFP avec une large utilisation puisqu’il peut fournir une bande passante plus haute. 

CFP

CFP, qui signifie facteur de forme C enfichable, est un accord multisource pour produire un facteur de forme commun de transmission de signaux numériques à grande vitesse. Le C représente la lettre latine C utilisée pour exprimer le nombre 100 (cent), puisque la norme a été développée pour le système 100 Gigabit Ethernet. Le CFP peut supporter une large gamme d’applications 40 et 100 Gb/s telles que 40 G et 100 G Ethernet, OC-768/STM-256, OTU3, et OTU4. 

QSFP28

Le module optique QSFP28 100 G est un produit de haute densité et de grande vitesse conçu pour les applications 100Gbps. Il possède le même format que le module optique QSFP+. Il fournit quatre canaux de grande vitesse aux signaux différents avec des débits de données allant de 25 Gbps à potentiellement 40 Gbps, et il peut finalement répondre aux exigences d’InfiniBand EDR (débit amélioré) de 100 Gbps Ethernet (4 × 25 Gbps) et de 100 Gbps 4X. Actuellement, il est généralement disponible dans plusieurs normes : 100GBASE-SR4, 100GBASE-LR4, 100GbASE-PSM4 et 100GBASE-CWDM4. QSFP28-100G-SR4 fonctionne sur une fibre multimode de 100 m. Alors que 100GBASE-LR4 QSFP28 supporte une distance beaucoup plus longue qui est de 10 km. Comparé au CFP, le QSFP28 est plus populaire dans le marché de modules optiques 100 G.

Les facteurs à considérer lors de l'achat d'un module optique

Voici les 4 points importants : Distance de transmission

Les distances de transmission que les modules optiques supportent sont différentes. En général, la distance de transmission du module optique multimode est beaucoup plus courte que celle de module optique monomode, et le prix du module optique multimode est moins cher.

Mode de transmission

Il existe trois modes de transmission des données du module optique : simplex, semi-duplex et en duplex intégral, la transmission simplex accepte la transmission de données dans une seule direction. La transmission semi-duplex permet la transmission de données dans deux directions, mais à un moment donné, une seule direction de transmission de données est autorisée. La transmission en duplex intégral permet de transmettre simultanément des données dans les deux sens. Il est préférable de choisir un module optique qui accepte la transmission en duplex intégral. Moyen de transmission

Les câbles en cuivre et les câbles optiques sont actuellement les deux supports de transmission les plus utilisés, certains modules optiques sont conçus comme des ports électriques et certains modules optiques sont conçus comme des ports optiques. Résistance à la chaleur

La température de fonctionnement du module optique ne doit pas être trop élevée. Si la température est trop élevée, une défaillance de liaison peut se produire. Par conséquent, choisissez un module optique avec une bonne résistance à la chaleur. Les points ci-dessus ne sont que des facteurs à prendre en compte lors de l'achat d'un module optique, la longueur d'onde de travail, le taux de travail et le fabricant sont également importants.

SFP 40 km VS. DWDM SFP: Which to Choose?

Small Form-factor Pluggable (SFP) is a compact, hot-pluggable transceiver used for both telecommunication and data communications applications. It is also called mini-GBIC for its smaller size, which is the upgraded version of GBIC transceiver. These 1Gb SFP modules are capable of supporting speeds up to 4.25 Gbps. And they are most often used for Fast Ethernet of Gigabit Ethernet applications. It interfaces a network device motherboard (for a switch, router, media converter or similar device) to a fiber optic or copper networking cable. SFP modules are commonly available in several different categories: 1000BASE-T SFP, 1000BASE-EX SFP, 1000BASE-SX SFP, 1000BASE-LX/LH SFP, 1000BASE-BX SFP, 1000BASE-ZX SFP, CWDM SFP and DWDM SFP. These modules support different distance according to the different Gigabit Ethernet standard. Today’s main subject will discuss SFP 40 km vs. DWDM SFP.

SFP 40 km

SFP 40 km transceiver is designed for highly reliable fiber optic network links up to 40 km. It is a cost effective transceiver designed to enable 1Gb for data center and core network applications. 1000BASE-EX SFP is the most popular SFP 40 km transceiver which runs on 1310nm wavelength lasers and achieves 40km link length. Except that, 1000BASE-BX BiDi SFP, 1000BASE-LH SFP and 1000BASE-LX SFP can also realize the transmission distance up to 40 km. The following will introduce these 1GbE SFP 40 km transceivers respectively.

1000BASE-EX SFP 40 km

1000BASE-EX SFP transceiver module is designed to connect a Gigabit Ethernet port to a network and has dual LC/PC single mode connectors. It operates on standard single-mode fiber-optic link spans of up to 40 km in length. The SFP Ethernet module provides a dependable and cost-effective way to add, replace or upgrade the ports on switches, routers and other networking equipment. Cisco GLC-EX-SM1550-40 and Cisco GLC-EX-SMD are 1G single mode fiber SFP 40 km modules for 1000BASE-EX Gigabit Ethernet transmission. GLC-EX-SM1550-40 supports a 1550nm wavelength signaling, while GLC-EX-SMD supports a 1310nm wavelength signaling.

1000BASE-BX SFP 40 km

1000BASE-BX SFP is a kind of BiDi transceiver, which can be divided into 1000BASE-BX-D SFP and 1000BASE-BX-U SFP. These two SFP transceivers must be used in pairs to permit a bidirectional Gigabit Ethernet connection using a single strand of single mode fiber (SMF) cable. The 1000BASE-BX-D SFP operates at wavelengths of 1490nm TX/1310nm RX, and the 1000BASE-BX-U SFP operates at wavelengths of 1310nm TX/1490nm RX.

1000BASE-BX-D BiDi SFP 40 km

Cisco GLC-BX40-D-I and GLC-BX40-DA-I are pluggable fiber optical transceivers for Gigabit Ethernet 1000BASE-BX and Fiber Channel communications. They support link length of up to 40 km point to point on single mode fiber at 1Gbps bidirectional and use an LC connector. The GLC-BX40-D-I transceiver transmits a 1490nm channel and receives a 1310nm signal, whereas GLC-BX40-DA-I transmits at a 1550nm wavelength and receives a 1310nm signal.

1000BASE-BX-U BiDi SFP 40 km

Similar to 1000BASE-BX-D 40 km SFP , Cisco GLC-BX40-U-I and GLC-BX40-UA-I also support link length of up to 40 km point to point on single mode fiber at 1Gbps bidirectional and use an LC connector. The main difference is the wavelength: GLC-BX40-U-I transmits a 1310nm channel and receives a 1550nm signal, whereas GLC-BX40- UA-I transmits at a 1310nm wavelength and receives a 1490nm signal. A GLC-BX40-D-I or GLC-BX40-DA-I device connects to a GLC-BX40-U-I or GLC-BX40-UA-I device with a single strand of standard SMF with an operating transmission range up to 40 km.

1000BASE-LX SFP 40 km

1000BASE-LX is a standard specified in IEEE 802.3 Clause 38 which uses a long wavelength laser. The “LX” in 1000BASE-LX stands for long wavelength, indicating that this version of Gigabit Ethernet is intended for use with long-wavelength transmissions (1270 - 1355nm) over long cable runs of fiber optic cabling. Allied Telesis AT-SPLX40 and Allied Telesis AT-SPLX40/1550 are 1000BASE-LX SFP single-mode modules supports Gigabit Ethernet over single-mode cables at distances up to 40 km. AT-SPLX40 operates over a wavelength of 1310nm for 40 km, whereas AT-SPLX40/1550 operates over a wavelength of 1550nm.

1000BASE-LH SFP 40 km

Unlike 1000BASE-LX, 1000BASE-LH is just a term widely used by many vendors. Long Haul (LH) denotes longer distances, so 1000BASE-LH SFP modules operate at a distance up to 70 km over single mode fiber. Cisco Linksys MGBLH1 is a easy-to-install modules that provide a simple way to add fiber connectivity or to add an extra Gigabit Ethernet port to switches. The MGE transceiver can support distances up to 40 km over single-mode fiber at a 1310nm wavelength.

DWDM SFP

DWDM SFP transceivers are used as part of a DWDM optical network to provide high-capacity bandwidth across an optical fiber network, which is a high performance, cost effective module for serial optical data communication applications up to 4.25Gb/s. DWDM transceiver uses different wavelengths to multiplex several optical signal onto a single fiber, without requiring any power to operate. There are 32 fixed-wavelength DWDM SFPs that support the International Telecommunications Union (ITU) 100-GHz wavelength grid. The DWDM SFP can be also used in DWDM SONET/SDH (with or without FEC), but for longer transmission distance like 200 km links and Ethernet/Fibre Channel protocol traffic for 80 km links. Cisco C61 DWDM-SFP-2877-40 is a 1000BASE-DWDM SFP 40km transceiver, which is designed to support distance up to 40 km over single-mode fiber and operate at a 1528.77nm DWDM wavelength (Channel 61) as specified by the ITU-T.

SFP 40 km VS. DWDM SFP

Transmission Medium

Generally, the standard SFP 40 km transceivers transmit through the single mode fiber, while DWDM SFP carries signals onto a single optical fiber to achieve maximum distances by using different wavelengths of laser light. So the DWDM SFP transceivers do not require any power to operate.

Wavelength

The standard SFP 40 km transceivers support distances up to 40 km over single-mode fiber at a 1310nm/1550nm wavelength. (the BiDi SFP has 1490nm/1550nm TX & 1310nm RX or 1310nm TX & 1490nm/1550nm RX ). However, DWDM SFP operates at a nominal DWDM wavelength from 1528.38 to 1563.86nm onto a single- mode fiber. Among them, 40 km DWDM SFP operates at a 1528.77nm DWDM wavelength (Channel 61).

Application

DWDM SFP is used in DWDM SONET/SDH, Gigabit Ethernet and Fibre Channel applications. These modules support operation at 100Ghz channel. The actual SFP transceiver offers a transparent optical data transmission of different protocols via single mode fiber. And for back-to-back connectivity, a 5-dB inline optical attenuator should be inserted between the fiber optic cable and the receiving port on the SFP at each end of the link.

Price

DWDM provides ultimate scalability and reach for fiber networks. Boosted by Erbium Doped-Fiber Amplifiers (EDFAs)  - a sort of performance enhancer for high-speed communications, DWDM systems can work over thousands of kilometers. Most commonly, DWDM SFP is much more expensive than the standard SFP. You can see the price more clearly in the following cable.

Conclusion

1000BASE SFP transceiver is the most commonly used component for Gigabit Ethernet application. With so many types available in the market, careful notice should be given to the range of differences, both in distance and price of multimode and single-mode fiber optics. Through SFP 40 km vs. DWDM SFP, if you are looking for SFP modules over long distance and with better scalability, DWDM SFP module is the ideal choice.

How to Realize 16 Channels Transmission in DWDM Network?

DWDM MUX/DEMUX plays a critical in WDM network building. 16 channels transmission is very common in DWDM networks. How to realize it in a simple way? This article intends to introduce two solutions to achieve 16 channels with different types of components. Which one is more cost-effective and competitive? The comparison between the them also will be explored. Hope it will help you when choosing fiber mux for your DWDM networks.

Solutions to Achieve 16 Channels Transmission in DWDM Network

In order to illustrate the solution more clearly, I take two types of DWDM MUX/DEMUX as an example. One is the traditional 16 channels dual fiber DWDM MUX/DEMUX. Another is two FMU 8 channels dual fiber DWDM MUX/DEMUX. The latter has an expansion port.

Solution One: Using Traditional 16 Channels DWDM MUX/DEMUX

The 16 channel DWDM MUX/DEMUX is a passive optical multiplexer designed for metro access applications. It’s built fiber mux and demux in one unit and can multiplex 16 channels on a fiber pair. In addition, this type of fiber mux also can be added some functional ports like expansion port, monitor port and 1310nm port, which make it possible to increase network capacity easily. The following is a simple graph showing the 16 channels transmission with this traditional DWDM MUX/DEMUX.

Solution Two: Using Two FMU 8 Channels DWDM MUX/DEMUX Modules

The FMU 8 channels DWDM MUX/DEMUX provide 8 bidirectional channels on a dual strand of fiber. Usually they are used together. Unlike the 16 channels DWDM MUX/DEMUX, this FMU 8 channels one has a more compact size, for it only occupies half space in a 1U rack. Put two FMU 8 channels DWDM MUX/DEMUX modules into one 1U two-slot rack mount chassis. two 8 channels DWDM MUX/DEMUX with different wavelengths are connected through the expansion port to realize 16 channels transmission in a DWDM network. Here is a graph showing how to achieve 16 channels DWDM transmission with these two 8m channels fiber muxes. As shown in the figure, two 8 channels DWDM MUX/DEMUX with different wavelengths are connected through the expansion port to realize 16 channels transmission in a DWDM network.

16CH DWDM MUX and Two FMU 8CH DWDM MUX: What’s the Difference When Deployed?

From the content above, we can see both solutions can realize the 16 channels transmission in a DWDM network. Then, are there differences between them? Or which is more competitive? Here is a simple analysis of the two solutions.

Firstly, comparing the two graphs above, the FMU 8 channels DWDM MUX/DEMUX are connected together by an expansion port, that’s why it can deliver 16 channels services like the traditional one. Except for connecting 8 channels DWDM MUX/DEMUX, the FMU fiber mux with expansion port also can be combined with other channels fiber mux like 2 channels, 4 channels or other channels, which offer more flexibility for optical network deployment and upgrade. And you can add DWDM into CWDM networks at some specific wavelengths with FS.COM FMU fiber mux.

Secondly, DWDM MUX/DEMUX price is always an important point that many network operators pay attention to. Therefore, when buying a fiber mux, the cost is a critical point to consider. If you search on Google, you will find the lowest price is $1100 in FS.COM. And the cost of using two 8 channels MUX/DEMUX is the same as the deployment of one 16 channels MUX/DEMUX. However, compared with the 16 channels DWDM MUX/DEMUX, the FMU 8 channels fiber mux provides a competitive solution for small networks which needn’t to buy a full-channel fiber mux that supports all 16 channels or more channels.

Conclusion

From the comparison above, the FMU 8 channels DWDM MUX/DEMUX is more flexible and cost-effective when deployed in WDM networks. How to choose is based on the requirements of your networks. FS.COM supplies two different types of these WDM MUX/DEMUX. Here is a simple datasheet of them. If you have more requirements for additional wavelengths, welcome to visit www.fs.com for more detailed information.
