Commonly used units for optical modules
(abbreviated IB) is a computer-networking communications standard used in high-performance computing that features very high throughput and very low latency. 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. Its main function is to convert between electrical and optical signals during optical signal transmission. Considering that some newcomers to optical modules may not understand the letters on the optical module or the.
