AOC Cable Structure Function and Development

Sep. 18, 2020

The active optical cable is composed of integrated optoelectronic devices. It is used for high-speed, high-reliability interconnection transmission equipment between data centers, high-performance computers, large-capacity memory, and other equipment. It usually meets industrial standard electrical interfaces through internal The electricity-to-light-to-electricity conversion uses the advantages of optical cables for data transmission. Simply put, the active optical cable can be regarded as a system composed of two optical transceivers and an optical cable jumper, but this system has a higher speed and better reliability than a system composed of independent components.

Compared with traditional cables, active optical cables integrate multi-mode optical fiber cables and optical transceivers and control chips. It has many advantages such as high transmission rate, long transmission distance, low energy consumption, and convenient use. It can help communication equipment to enjoy the huge optical transmission. The advantage is an ideal transmission cable for data centers, consumer electronics, and other fields.

Especially driven by the demand of cloud computing environment, active optical cables have a wide range of applications in server clusters, network switches, telecommunication switching centers, and other fields that require high-speed data transmission and high-performance embedded communications. Its system applications include data Aggregation, backplane communication, unique protocol data transmission, and other high-density and high-bandwidth applications.

Development status of active optical cable

The active optical cable (AOC) market has been developing since 2007 and has now expanded to the peripheral markets of high-speed data and some video communications; starting from high-performance computers, it has spread to traditional data centers with multiple protocols, and the application of active optical cables The prospects are widely optimistic. In 2012, the global active optical cable (AOC) market exceeded the forecast by 65%. The main growth point is that the 14G InfiniBFDR active optical cable (AOC) segment has a faster-than-expected growth rate.

At this stage, the InfiniBand market occupies the largest share and has moved to 14G FDR QSFP, while the traditional data center still stays in the 10G SFP format. In addition to data center transmission networks, AOC has also been widely used in consumer electronics, such as high-definition multimedia interface (HDMI), third-generation universal serial bus and Thunderbolt, etc., more and more high-speed circuits and Providers of optical communication solutions have begun to develop and manufacture various types of AOC, and continue to attract more companies to enter the market.

Active Fiber Optic Cable (AOC) also has potential in other protocols, such as SAS, Fiber Channel, and PCI Express, which have transmission rates in excess of 10G. As more and more protocols move toward higher line speeds, the transmission distance and electromagnetic interference issues of copper cable links become apparent, and active cables offer powerful advantages in terms of high speeds, long distances and low prices. This has helped fuel the FIbre-optic cable (AOC) business.
