Why are optical modules matched
In the optical fiber network system, the correct matching of optical modules and patch cord is very important, which is not only related to the stability of network connection, but also affects the efficiency and quality of data transmission. An optical module usually consists of an optical transmitting device (TOSA, including a laser), an optical receiving device (ROSA, including a photodetector), functional circuits,main control circuit board (PCBA), housing and optical (electrical) interface and other components. Optical modules typically have an electrical interface on the side that connects to the inside of the system and an optical interface on the side that connects to the outside. The optical module offers an effective high-speed solution for a growing telecom market. Data rates range from 155 Mbps to 6 Gbps and even up to 10 Gbps. However, the basic structure of an optical module includes some common parts, as shown in Figure 1-2.
