The fiber optic device responsible for converting a weakened and distorted optical signal back to an electrical signal is a fiber optic receiver. A fiber optic receiver is an electro-optic device that accepts optical signals from an optical fiber and converts them into electrical signals. A typical fiber optic receiver consists of an optical detector, a low-noise amplifier, and other circuitry used to produce the output electrical signal. The optical detector converts the incoming optical signal into an electrical signal. The amplifier then amplifies the electrical signal to a level suitable for further signal processing. The type of other circuitry contained within the receiver depends on what type of modulation is used and the receiver electrical output requirements. Topics: Principal properties of an optical detector and fiber optic receiver Optical detector performance Capability requirements for the implementation of fiber optic systems Main components of a fiber optic receiver Receiver sensitivity, dynamic range, and other key operational parameters Receiver performance Intended Audience: This course is intended primarily for Telecom, Systems, Electrical, Mechanical, Civil, and other engineers whose job description requires a comprehensive knowledge of fiber optics infrastructure.
