Optical Components
TOSA（Transmitter Optical Subassembly）is a Optical Subassembly which conversion of electrical signals into optical signals (E/O conversion),The main performance indexes of TOSA include optical power value (Po), central wavelength (λC) and so on.
ROSA(Receiver Optical Subassembly)is a Optical Subassembly which converting optical signals into electrical signals (O/E conversion)，The main performance indexes are sensitivity (Sen) and so on. The unit of sensitivity is dBm, which means that under certain conditions, ROSA can receive the minimum optical power value.
