Fiber optic transceivers are key components of fiber optic transmission network. They are designed in small form-factor with some integrated optical sub-assemblies which can be suitable for high-density network. The major cost components of a transceiver module are the transmitter optical sub-assembly (TOSA), which converts an electrical and the receiver optical sub-assembly (ROSA). However, inside a BiDi (Bi-Directional) transceiver, there is a component with called "BOSA" (Bidirectional Optical Sub-Assemblies) which acts the role of TOSA and ROSA but with different principle.

Semiconductor lasers used in fiber optics industry are small, sensitive devices. They are typically a few hundred mic ... Read more »
