What is coherent detection in optical fiber?
Coherent detection allows information to be encoded with two degrees of freedom, which increases the amount of information per channel. From: Optical Fiber Telecommunications VII, 2020.
What is coherent detection technique?
Coherent detection is an optical signal detection technique that is useful both in fiber-optic communication systems and in optical measurement and sensors. It uses a local oscillator at the receiver, enabling 100Gbit/s transport on a single wavelength for long-haul DWDM networks.
What is meant by coherent and non coherent detection?
Non-coherent means optical transmission system does not require coherent local oscillator light; Coherent means optical transmission system that uses local oscillator light for coherent detection.
What is coherent technology in DWDM?
The advent of coherent DWDM technology is enabling 100GE optical transport over backbone optical networks with link engineering rules similar to 10 Gb/s OOK channels. This enables a 10× scaling of network/fiber capacity and is possible without any change in DWDM channel spacing or DWDM common equipment design.
