Overview
The 5G fronthaul passive WDM system launched by TRUSTNUO Communication is mainly used to solve the problem of lack of optical fiber transmission cable resources between DU-AAU in the C-RAN architecture.
By deploying passive wavelength division multiplexers on the DU and AAU sides, the The matching color light module replaces the original white light module on the wireless device, thereby providing business optical signals of different wavelengths, and the passive wavelength division multiplexers on both sides multiplex the business optical signals of different wavelengths on one core fiber for bidirectional transmission, instead of laying optical cables, providing operators with a low-cost, high-performance optical fiber expansion solution.
Features
- Supports CPRI 1~10 and eCPRI (10G/25G), compatible with STM-1/4/16/64, GE/10GE/25GE and other multi-service unified bearing, transparent transmission, and maximizing the value of the pre-processing network
- Extends the physical channel of purely transparent transmission without changing the network structure, without introducing delay and jitter
- Modular configuration, 1:6/12/18 optional, can realize multi-directional and multi-level convergence, large-scale fiber savings
- A variety of color light modules can be provided, supporting CWDM 18-wave and MWDM 12-wave to meet the requirements of various line power budget indicators
- Pure passive working environment, reducing points of failure, plug-and-play, no configuration, simple maintenance
- The WDM multiplexer is compact and lightweight, and supports rack, wall-mounting, pole-mounting and other installation methods
- Brand: TRUSTNUO
