Application of WDM (passive wavelength division multiplexer) in 5G fronthaul
Oct 25 , 2022
Passive wavelength division multiplexer (WDM) designed to address fiber resources for long-haul transmission between distributed units (DUs) and active antenna units (AAUs) in Centralized Radio Access Network (C-RAN) 5G fronthaul architectures In addition, passive WDM can save fiber resources. In passive WDM, color optical modules are directly deployed on AAUs and DUs, and multiple AAUs can share ...

What are the performance indicators that affect the WDM wavelength division multiplexer?
Nov 15 , 2022
The technology of simultaneously transmitting information of two or more optical wavelength signals through different optical channels in the same fiber is called wavelength division multiplexing (WDM). WDM (Wavelength Division Multiplexing) is to combine two or more optical carrier signals of different wavelengths (carrying various information) at the transmitting end through a multiplexer, and c...

About DWDM Erbium-doped Fiber Amplifier
Jan 11 , 2023
In a longer fiber-optic line, DWDM Erbium-doped Fiber Amplifier are installed at specified distances for the purpose of ensuring the recovery of signals weakened by the fiber. Erbium-doped fiber amplifier EDFA can amplify any form of optical signal, and, at the same time, to recover a large number of independent WDM channel signals. However, Erbium-doped fiber amplifiers, which provide power ampli...
