What role does PCB play in the development speed of optical communication chips?
1. Emitting chip and edge emitting chip Laser chips can be divided into surface-emitting chips and edge-emitting chips according to the light output structure. Surface-emitting chips include VCSEL chips, and edge-emitting chips include FP, DFB, and EML chips. There are two main types of detector chips: PIN and APD. 2. Application scenarios of optical communication chips In the field…
