FAQ's

Which are the latency constraints for optical Backhaul/Fronthaul connection?

The fronthaul RAN optical connection between either remote radio units (RRU) and baseband units (BBU) or BBU and AAU antenna panel has narrow latency constraints with a maximum latency of 75μs. Obviously the higher is the total latency, the shortest are the achievable distances. As an example considering an optical equipment with latency of 0.5 μs, then the maximum supported distance is 15 km.

What is DWDM and why used extensively in Optical fronthaul?

Dense Wavelength Division Multiplexing (DWDM) is a technique of multiplexing several optical signals over a fiber . It is based on colored optical modules, filters and optionally transponders. It is a mature and well-established technology capable of improving fiber capacity and efficiency by multiplexing multiple wavelengths over a single fiber.
