5G Fronthaul Passive WDM Solution

In the 5G era, the wireless network basically adopts the C-RAN site-building mode, and DU is deployed in a centralized manner. Some 5G remote sites will be co-located with the existing 4G remote sites. There is an urgent need for the fronthaul of base stations with deep coverage, and the fiber direct-drive 5g fronthaul solution exists. There are a series of problems such as serious consumption of optical fiber resources and difficulty in expansion. As a one-stop solution service provider for optical communications, Guangzhou Sintai Communication Technology Co., Ltd. has launched a 5G fronthaul passive WDM solution for this purpose.

5G Fronthaul Passive WDM Solution Features

Support CPRI 1~10 and eCPRI (10G/25G), compatible with STM-1/4/16/64, GE/10GE/25GE and other multi-service unified bearers, transparent transmission, maximize the value of fronthaul network

Without changing the network structure, expanding the physical channel of pure transparent transmission, without introducing delay and jitter

Modular configuration, 1:6/12/18 optional, can achieve multi-directional multi-level convergence, large-scale fiber saving

A variety of color light modules can be provided, supporting dwdm 5g 18 waves, MWDM 12 waves, and meeting various line power budget index requirements

Pure passive working environment, reducing failure points, plug and play, no configuration, simple maintenance

The passive wavelength division multiplexer is small and light and supports multiple installation methods such as rack-mounted, wall-mounted, pole-mounted, etc.

5G Fronthaul Passive WDM Solution Application Scenario

Mainly meet the needs of end point-to-point CRAN networking scenarios, the distance between DU and AAU sites is within 10km

In areas where optical fiber resources are scarce, there are no pipeline resources and new optical fibers are laid unconditionally

When limited by the construction period, it can be used as an emergency solution to temporarily solve the fiber problem
