The receiver detects the incoming light and converts it back into an electrical signal. It utilizes photodetectors, such as PIN photodiodes or Avalanche Photodiodes (APDs). APDs offer internal gain, providing higher sensitivity for weak signals. Key Principles Covered in Gowar's Text
Every optical communication network relies on three primary elements to transmit information over long distances. 1. The Optical Transmitter
