Introduction Avalanche Photodiode At the output end of an optical transmission line, avalanche photodiode there must be a receiving device which interprets the information contained in the optical signal. The first element of this receiver is a photodetector. The photodetector senses the luminescent power falling upon it and converts the variation of this optical power

Single-Mode Fiber Connectors Because of the wide use of single mode fiber connectors optic links and because of the greater alignment precision required for these systems, this section addresses single-mode connector coupling losses. Based on the gaussian-beam model of single-mode fiber fields the following equation gives the coupling loss (in decibels) between single-mode fibers that

Basics of serial communication The serial communication port is full duplex, meaning that it can transmit and receive simultaneously. It is also a receive buffered, meaning that it can commence reception of the second byte before a previously received byte has been read from the receive register. The serial communication port receive and transmit registers

One of the most important components in any optical fiber communication system is the optical fiber itself, since its transmission characteristics play a major role in determining the performance of the entire system. Some of the questions that arise concerning optical fiber communication are What is the structure of an optical fiber? How does light
