WDM in 5G Fronthaul

WDM in 5G Fronthaul

Passive WDM is suitable for end-to-end C-RAN network scenarios, areas where optical fibers are scarce, and areas that lack pipeline resources. Potential application scenarios of passive WDM include: 5G fronthaul, oil and gas, industrial, electric power, mining, cable television, FTTx, passive optical network, etc.

In passive WDM, colored optical modules are directly deployed on AAUs and DUs, and multiple AAUs can share one optical fiber for transmission through passive WDM without power supply at the remote end. Passive WDM is the most suitable solution for 5G fronthaul. According to different wavelengths, 5G passive wavelength division multiplexers can be divided into CWDM (Coarse Wavelength Division Multiplexing), DWDM (Dense Wavelength Division Multiplexing), MWDM (Medium Wave Division Multiplexing) and LWDN (Wavelength Division Multiplexing).

WDM Solution Advantage

The solution of carrying passive WDM in 5G fronthaul has the following advantages: high bandwidth, high reliability, cost-effective CPRI rate, low latency, low insertion loss, low cost, 4/6/8/12/18/24 /48 optional channels, significantly saving fiber, plug and play, easy to install and deploy, easy to maintain.
