What advantages of the Active optical cables have? Where is AOC cables application to?

Active fiber optic cable is to meet the higher density and higher broadband applications and the birth of the product, with the rapid development of optical network era, has gradually penetrated into the global high-speed interconnect market every corner.

What is an active optical cable?
Active optical cable (Active Optical Cables, referred to as AOC) is equipped with optical transceiver at both ends of the fiber jumper, the need for external energy to complete the optical / electrical signal conversion. The main components of the active cable are divided into two parts: optical path and circuit. The optical path part includes the lens and FA for converting the optical path angle. The circuit part includes PCB board, substrate, VCSEL chip, VCSEL driver chip, PD chip and TIA chip. As a major transmission medium for high-performance computers and data centers, active optical cables ensure the stability of transport and the flexibility of the application, which is common in high-density applications.

Second, the principle of active cable
At the end of the active fiber optic cable, the data input electrical signal is converted into an optical signal of a specific wavelength through the photoelectric conversion device. The optical signal is modulated and coupled into the transmission cable. After the optical signal arrives at the other end, the photoelectric detection device The optical signal is detected and amplified, processed, and then output the corresponding electrical signal. Opposite direction transmission principle is the same.

Third, the advantages of Active optical cables

Active optical cable compared with high-speed cable:
1, the transmission power on the system link is lower;
2, the volume is about half of the copper, the weight is only a quarter of high-speed cable;
3, in the room cabling system, the air flow better, more heat dissipation;
4, the bending radius of the cable is smaller than the copper;
5, the transmission distance farther, you can reach 100 to 300 meters;
6, the product transmission performance of the bit error rate is better, BER up to 10 ^ -15.
Active optical cable compared with the optical transceiver module:
1, the optical cable optical interface is not exposed, that is, there is no optical interface cleaning and contamination problems;
2, the system stability and reliability is higher;
3, the network system more convenient management and maintenance;
4, greatly reduce the operation and maintenance costs, improve efficiency.
Fourth, the application of active cable in which areas?

The application of active cable is mainly in the following three areas:
1, in the teaching center and the laboratory, the active cable to more than one machine connected with the host, not only to ensure high-speed data transmission, but also to achieve a secure network system.
2, in the data center and cloud computing system, to achieve higher bandwidth and lower power requirements, active optical cable 10G SFP + and 40G QSFP+ active optical cables can be a good connection with high-speed optical communication port switches or routers and other equipment.
3, in the common digital signage, the active optical cable also played an important role in the outdoor HDMI environment to meet the 1080p resolution, not only that, outdoor large-scale interactive games are also useful to the active cable.
