AOC active optical cable
Release Date: 2021-11-05

The amount of information transmission and exchange is increasing day by day, and there are more and more high-density and high-bandwidth applications. Traditional copper cables can no longer meet the needs of communication. Compared with traditional cables, active optical cables can help communication equipment to enjoy optical fiber. Great advantage of transmission. So what's the difference between AOC active optical cables?

一. What is an active optical cable?

AOC is the abbreviation of active optical cable, which is composed of integrated optoelectronic devices (two optical transceivers and multi-mode optical fibers), and is used for high-speed, high-reliability interconnection transmission between data centers, high-performance computers, large-capacity storage devices, etc. equipment.

However, compared with traditional cables, active optical cables are more convenient to use, have better reliability, and have lower energy consumption than traditional cables. At the same time, they have the characteristics of long transmission distance and high transmission rate. It brings great convenience and is also an ideal transmission cable for data centers and other fields.

二. the classification of active optical cables

1. 10G SFP+ AOC active optical cable

The housing of the 10G SFP+ AOC is a metal housing with EMI and anti-electromagnetic interference, using a package that supports hot-pluggable SFP+, and a high-reliability 850nm VCSEL laser and PIN receiver. Compared with traditional copper cables, it has the farthest The transmission distance can reach 300M, which overcomes the broadband limitation of traditional copper cables.

2. 25G SFP28 AOC active optical cable

25G SFP28 AOC active optical cable is suitable for 25G and 10G Ethernet, high-capacity IO and SFP+ interface, data center and rack-to-rack connection, with a throughput of up to 25Gbps, its volume and weight are two 25G high-speed cables. One-quarter and one-quarter, it is lighter than it; at the same time, it does not require equipment upgrades, and has better transmission performance and bit error rate, and is widely used in high-performance computing, data centers, and storage area networks.

3. 40G QSFP+ AOC active optical cable

40G QSFP+ AOC adopts four-channel full-duplex active optical cable, the transmission rate of each channel can reach up to 11.3Gbit/s, multi-mode optical fiber is connected to high-performance VCSEL light source, in the application of short-distance network transmission, compared with 40G optical module , without insertion loss and return loss, its material cost and maintenance cost are relatively low, which can help users save more costs, mainly used in cloud computing systems and data center computer rooms.

4. 100G QSFP28 AOC active optical cable

100G QSFP28 AOC active optical cable and 40G QSFP+ AOC both use four-channel full-duplex active optical cable, 100G QSFP28 AOC active optical cable has a bandwidth of 100 Gbps, and uses a multimode optical fiber system with a wavelength of 850nm. It is composed of two optical fibers. It consists of a transceiver and an optical fiber jumper, and both ends are a 100G optical module receiver, which can realize one-to-one transmission. Mainly used in data centers, high-performance computing and storage area networks, compatible with major brands of servers, switches, etc.

. the application of active optical cable

At present, the market of active optical cables is also constantly expanding. From the initial high-performance computer, it has spread to the traditional data center with multiple protocols, and the application is gradually extensive, not only can it connect multiple machines to the host, but also It has a wide range of applications in cloud computing, big data centers, high-speed data transmission, digital signage and other fields. It not only ensures high-speed data transmission, but also plays a role in more fields by virtue of its long transmission distance and good transmission performance. effect.
