5G Fronthaul Semi-Active WDM Sytem Feature
* Support CPRI 1~10 and eCPRI (10G/25G), compatible with STM-1/4/16/64, GE/10GE/25GE, and another multi-service unified bearing, transparent transmission, and maximize the value of frontal transmission network.
* Modular configuration, 1:6/12/18 optional, can achieve multi-directional multi-level convergence, and large-scale optical fiber saving.
* It can provide a variety of color optical modules, support CWDM 18 waves, MWDM 12 waves, meet the requirements of various line power budgets.
* Support optical layer 1:1 protection with protection switching time less than 50ms, improve network reliability.
* Support graphical interface network management, reconstruct wireless and transmission management domain and realize full monitoring of optical module and line status.
* The central office ends active WDM equipment supports AC 220 V and DC-48 V power supply options and 1 + 1 power input protection. Power failure of the equipment will not affect the service transmission.
* Remote passive WDM has outdoor deployment capability and flexible deployment location.
