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.

CWDM SFP vs DWDM SFP: ¿Cuál te queda mejor?

SFP (Small Form-Factor Pluggable) está diseñado para cumplir con los estándares del Acuerdo de Múltiples Fuentes (MSA) para garantizar la compatibilidad del equipo de red. Recientemente, la tecnología de multiplexación por división de longitud de onda (WDM) es muy bien recibida por los usuarios de Internet de todo el mundo. Es una tecnología que multiplexa varias señales de portadores ópticos en diferentes longitudes de onda de luz láser sobre una sola fibra óptica. Al usar la tecnología WDM, el módulo SFP puede tener diferentes longitudes de onda asignadas. El siguiente pasaje se centrará en las breves descripciones de CWDM SFP y DWDM SFP.

Descripción general de CWDM SFP

CWDM SFP es un tipo de transceptor óptico que utiliza tecnología CWDM. De manera similar con el módulo SFP tradicional, CWDM SFP es un dispositivo de entrada/salida intercambiable en caliente que se conecta a un puerto o ranura SFP de un switch o enrutador, conectando el puerto con la red de fibra óptica. Los módulos transceptores SFP de CWDM utilizan la interfaz SFP para conectar el equipo y utilizan una interfaz de conector dúplex LC/PC para conectar la red óptica. Los módulos CWDM SFP coloridos se muestran a continuación.

Es bien sabido que los módulos CWDM SFP vienen en 8 longitudes de onda que abarcan desde 1470nm hasta 1610nm. Las marcas de color en los dispositivos identifican la longitud de onda a la que se asigna el canal Ethernet Gigabit. La siguiente imagen enumera los CWDM SFP con sus longitudes de onda y códigos de color.

Descripción general de DWDM SFP

Los transceptores SFP DWDM (multiplexación por división de longitud de onda densa) se utilizan como parte de una red óptica DWDM para proporcionar ancho de banda de alta capacidad en una red de fibra óptica, que es un módulo de alto rendimiento y rentable para aplicaciones de comunicación de datos ópticas en serie de hasta 4.25 GB/s. Hay 32 longitudes de onda fijadas de SFP DWDM que admiten la red de longitud de onda de 100 GHz de la Unión Internacional de Telecomunicaciones (UIT). A continuación, se muestra una estructura interna de DWDM SFP.

Aplicación

El transceptor SFP CWDM se usa ampliamente en comunicaciones ópticas para telecomunicaciones y comunicación de datos. Está diseñado para operaciones en anillos de acceso Metro y redes punto a punto que usan redes ópticas sincrónicas (SONET), jerarquía digital síncrona (SDH), Gigabit Ethernet y equipos de red Fibre Channel. El DWDM SFP también se puede usar en DWDM SONET/SDH (con o sin FEC), pero para una distancia de transmisión más larga como enlaces de 200 km y tráfico de protocolo Ethernet/Fibre Channel para enlaces de 80 km.

¿Cuál debería elegir, CWDM SFP o DWDM SFP?

Desde un punto de vista de bajo costo, el módulo CWDM SFP es económico que DWDM SFP. Proporciona una solución conveniente y rentable para la adopción de Gigabit Ethernet y Fibre Channel. Por otro lado, la clave para seleccionar CWDM o DWDM SFP radica en la diferencia entre CWDM y DWDM. Se refieren a diferentes métodos para dividir la luz. Por ejemplo, CWDM utiliza un espaciado más amplio entre canales, lo que permite SFP de bajo costo, y DWDM utiliza un espacio de canal más denso, lo que permite que se usen más longitudes de onda en una sola fibra. DWDM se usa generalmente en redes ópticas grandes a mayor distancia. Por lo tanto, si está buscando módulos SFP a larga distancia y con una mejor escalabilidad, el módulo DWDM SFP es la opción ideal.

Espero que esta breve introducción a CWDM/DWDM SFPs haya sido útil para que puedas elegir al seleccionarlos. Los SFP CWDM de Fiberstore se basan en los SFP Cisco CWDM con transceptor multivelocidad para velocidades de datos de 100 Mbps hasta 4 Gbps, distancia de transferencia a 20-40 km, 40-80 km y 80-120 km con diferentes colores que marcan las opciones que mejor satisfacen el requisitos de clientes. Todos los módulos DWDM SFP cumplen con los requisitos del estándar IEEE802.3 Gigabit Ethernet. Son adecuados para las interconexiones en entornos Gigabit Ethernet y Fibre Channel.

CWDM and DWDM for Metro Networks: How to Make it Economical?

Fiber exhaust still appears to be a common problem faced by most metro (or metropolitan) networks. Although the cost of fiber optic cable is consistently dropping, the trenching, labor, and other installation costs towards optical fiber stay rather high. This may partially explain why an increasing number of metro networks incline to adopt WDM technology to enhance fiber capacity. It is known that WDM technology used in metro networks generally takes two forms: coarse WDM (CWDM) and dense WDM (DWDM). This article will deliver an overall comparison of CWDM and DWDM in metro networks, from the perspective of the roles each plays and the operating cost. Help you to decide how to reach an economical solution.

CWDM vs. DWDM: Different Role in Metro Network

As for the major difference between the two WDM technology, their names imply it all: is the channel spacing within the window of the optical spectrum (see the picture below). CWDM has a wider pass-band that spaced at 20 nm apart, which allows for the use of less expensive components like uncooled lasers and thin-film filter technology. The cost advantage of CWDM makes it a more appropriate alternative for the shorter distance typically found in metro access networks.

However, metro networks sometimes demand for longer distance and more wavelengths that CWDM simply cannot satisfy, then DWDM with its narrow channel spacing (0.8 nm) should be put into use. The problem is that the components related to the latter are too expensive for some edge networks. In this case, the best solution is to combine both CWDM and DWDM in metro area networks.

CWDM in the Metro Access

CWDM nowadays commonly supports at least eight of the eighteen ITU-T G.694.2 defined channels over distances of up to 80 km. With simple point-to-point and ring network topology, CWDM eliminates the need for erbium doped-fiber amplifier (EDFA) typically associated with DWDM. CWDM's lower cost and small footprint fit well with customer premises and co-location installations. And due to the readily available of Gigabit interface converters and small form factor pluggable (SFP) transceivers for CWDM platform, it gains in much popularity in enterprise and storage networks. CWDM is most fit in networks with the following features:

Low channel count of 4 to 8 channels

Transmission rates of <2.5 Gbits/sec per channel, and short distances of <80 km

DWDM in the Metro Core

Carriers are consistently looking for a cheaper and simpler version of long-haul DWDM, which drives the equipment suppliers to adapt DWDM systems accordingly. Banded wavelength filters, elimination of dispersion compensation, and more tolerant channel spacing were seen as ways to accomplish this goal. Nowadays, DWDM is well suited to high-capacity core networks in the metro, and to regional extensions between metro areas.

Cost Concerning CWDM and DWDM

The cost is still presented as a key difference in metro network systems. DWDM lasers are generally more expensive than those applied in CWDM system, the cooled DFB lasers offer cost-effective solutions for high-capacity large metro rings. And the cost of the this system is amortized over the large number of customers served by the systems. Whereas for metro access networks that demand for lower-cost and lower-capacity systems, it heavily depends on what the customer is willing to pay for broadband service. Since a metro access application would have fewer wavelengths, so based on equipment cost, CWDM is a more profitable solution for metro access points where cost is more important than capacity.

The Future of CWDM and DWDM in Metro Network

Some vendors offering both CWDM and DWDM technologies have merged the system building blocks onto a single platform. This approach allows the de-multiplexed CWDM traffic to be directly connected to DWDM transponders, saving equipment and space. It also enables end-to-end performance monitoring and cost optimization throughout the entire metro network. Then there is no need to choose between these two WDM technologies. The better choice is an integrated solution that makes use of the economies of CWDM for shorter distances, and provides the power of a DWDM network where longer distances and more capacity are needed. The result is an integrated, economical network that doesn't require a carrier to compromise on quality, quantity, or cost. The DWDM building blocks are shown below.

Conclusion

From what we have discussed in this article, we can conclude that metro networks will benefit from the mixture of CWDM and DWDM systems. And metro networks are becoming more flexible over this converged solution: with CWDM fitting the needs of today, and DWDM for the growing demand for increased coverage in the future. Take advantage of both the coarse and dense WDM technology, this integrated metro network that delivers much reliability and flexibility is the trend of the future.
