Abstract: For high-bit-rate long-haul fiber optic communications, the avalanche photodiode (APD) is frequently the photodetector of choice owing to its internal gain, which provides a sensitivity margin relative to PIN photodiodes. The module is powered by positive 12V, and the input optical interface is optional for optic fiber or space incidence. Sudden decreases in measured power on one input port can indicate an amplifier failure or cable cut near that input port. 6.7.4 Avalanche Photodiode (APD) 6.8 Photoconductive detectors.

Avalanche photodiode is one of photodiodes can be operated in high electric field in order to achieve high bit rate optical fiber communication systems. APDs can achieve 5-10-dB better sensitivity than PINs, provided that the multiplication noise is low and the gain-bandwidth product is sufficiently high. Particles called charge carriers enter the diode and are exposed to an electrical field. A new development in semiconductor technology, leading to an ultrafast, highly sensitive avalanche photodiode (APD) with extremely low excessive noise, could improve data transmission rates and/or enable longer transmission distances. In this chapter we briefly discuss the basic principle of operation of two commonly used photodiodes – namely, PIN (p-doped, intrinsic, and n-doped layers) diode and avalanche photodiodes (APD) – and study their important characteristics that are of particular relevance to optical fiber communication systems. Receivers are integral part of a long distance fiber optic communication system. D. 770 nm to 10^6 nm . S. E. Miller and A. G. Chynoweth, Academic Press (1979) Range of infrared .
