808nm DFB lasers are the DFB Narrow Widthline Lasers with wavelength of 808nm .
850nm IR APD Avalanche Photodiode ROSA. APD ( avalanche photodiode ) is a highly sensitive type of photodiode, which in general are semiconductor diodes that exploit the photoelectric effect to convert light into electricity. APDs use materials and a structure optimised for operating with high reverse bias, approaching the reverse breakdown voltage, such that charge carriers generated by the photoelectric effect are multiplied by an avalanche breakdown; thus they can be used to detect relatively small amounts of light.
ROSA & Photo Diodes
ROSA is a Laser Receiving part to convert optical signals into electrical signals at the receiving end. Sensitivity is the key to performance judgement. It is composed of a detector and an adapter. The detectors can be divided into PIN-TIA and APD-TIA, and the adapters have two types of metal and plastic PE parts.
