Data Center Cabling Solution: Active Optical Cable

As data rates rise and data center grows in size, copper cable is getting stretched to its limits. However,  active optical cable (AOC) has emerged to replace copper cable in data centers and high-performance computing (HPC) applications. It provides high-speed, high reliability, high flexibility, and low power consumption. This article will provide some knowledge of AOC cable. 

What is an Active Optical Cable?

Active optical cable (AOC) is an optical fiber jumper cable terminated with optical transceivers on both ends. It uses electrical-to-optical conversion on the cable ends to improve the speed and distance performance of the cable without sacrificing compatibility with standard electrical interfaces.

Active Optical Cable Structure

AOC cable consists of the fiber optic connector and fiber cable. The connection between fiber cable and fiber optic connectors is not separable. If the fiber optic connector or fiber cable needs to be changed, they should be removed together. The electrical and optical signal conversion can be achieved right through each end of the optical fiber.

Active Optical Cable Types

There are several varieties of AOC cable available on the market , including 10G SFP+ AOC, 25G SFP28 AOC,40G QSFP+ AOC, 56G QSFP+ AOC, 40G QSFP+ to 4x SFP+ breakout AOC, 40G QSFP+ to 8x LC breakout AOC, 100G QSFP28 AOC, 100G QSFP28 to 4x SFP28 breakout AOC and 120G CXP AOC, etc. These AOC cables are commonly used for short-range multi-lane data communication and interconnect applications between two devices, such as rack-to-rack, shelf-to-shelf interconnect, storage, hubs, switches, routers, servers, etc.

Features and Benefits

AOC cable provides low power consumption, high density, high speed, high reliability, high security, small size, strong heat dissipation, low electromagnetic interference, long transmission distance, low energy consumption, low latency, lightweight, and ease of installation.

Application Scenarios

AOC Cable is used to connect top-of-row (ToR) switches to end-of-row aggregation switches, and to connect the ToR switch with storage subsystems at reaches greater than direct attach copper (DAC) limits of 3-7 meters. The following three scenarios show the specific applications.

Scenario 1:  AOC cable is used to connect two switches directly.

Scenario 2: The breakout AOC cable provides a highly cost-effective way to connect within racks and across adjacent racks. The following figure shows 40GbE QSFP+ to 4 x SFP+ AOC cable connecting to a 40G QSFP+ port switch on one end, and to four 10G SFP+ port switches on the other end.

Scenario 3: For the long-haul transmission between the two switches, a suitable solution is recommended to use single-mode patch cable, OEO converters, and AOC cables, which can provide seamless integration of different fiber types by converting multi-mode fiber to single-mode fiber.

Conclusion

AOC cable achieves high data rates over long reaches interconnection, which is the best solution for data centers and high-performance computing applications.

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.

✅ Кабели DAC 🌀 Альтернативой оптическим SFP и QSFP модулям, или-же трансиверам служат кабели DAC Их применяют в случаях, когда требуется соединить расположенное на небольшом расстоянии оборудование. Рассмотрим их назначение подробнее в данной статье. ✔️ Кабели DAC — что это и зачем В терминологии DAC полностью звучит как Direct Attach Copper Cable. В переводе с английского означает — «кабель для прямого медного подключения». Иными словами, это твинаксиальный кабель-переход��ик, предназначенный для соединения коммутаторов с серверами. Такого типа соединитель представляет собой экранированный медный коаксиальный или волоконно-оптический шнур, имеющий ограниченную длину и оснащенный закрепляющими трансиверами с обоих концов. Отметим, что трансиверы в этом случае могут быть разного формата — от SFP до QSFP28. Что касается длины проводника, то при внутренних соединениях ее показатель чаще всего находится в диапазоне от 1 до 20 метров. ✔️ Типы DAC проводников Отличительным параметром кабелей прямого подключения выступает длина. В основном они разделяются на два типа: 🔸 Пассивные 🔸 Активные Первый тип проводника выглядит как твинаксиальный кабель, который напрямую соединяется с РСВ трансивера, расположенного на его окончании. Длина такого переходника может достигать 7-ми метров (для 10G кабеля). Но во избежание рисков относительно стабильного функционирования проводника, многие производители не изготавливают их больше 3-ех метров. В свою очередь второй тип DAC кабелей представляют собой переходник с лазерным блоком, который соединен с РСВ. Таким образом, длина соединителя максимально достигает 20-ти метров для 10G кабеля и 3 метров для 100G кабеля. Отметим, что DAC проводники еще отличаются диаметром сечения токопроводящей жилы. Данный показатель характеризуется в AWG единицах. Соответственно, от AWG зависит максимальный уровень длины переходника. То есть, когда происходит увеличение длины, то одновременно повышается вносимое затухание. ⤵️ Полный текст в блоге AND-Systems: http://amp.gs/jliJR #andsystems #andpro #андсистемс #твинаксиальныйкабель #кабельдляпрямогомедногоподключения #кабелиdac

The modern data center consists of high-speed connectivity to customers throughout the world as well as flawless, high-flow media. Data enter vendors should maximize the density of optical transceiver ports on their Ethernet switches in order to offer a low-cost solution for connecting switches. DAC stands for direct attach a copper cable for 100G QSFP28. In addition, there is a 100G QSFP28 Copper Cable and an Ethernet DAC that can handle 100G. This cable is sometimes known as 100GBASE-CR4 QSFP cable. Each copper pair can transmit data at speeds of up to 25GbE per socket. QSFP28 cable assemblies are therefore suited for space-saving connectivity in data centers, networks, and high-performance computing applications.
