3C-LINK Semi-active WDM: Passive colored optical modules and multiplexer/demultiplexer units are deployed on the AAU side, and active WDM devices are deployed on the BBU side. One optical fiber can support access of six 25G eCPRI services. No need for power supply at the remote end.This solution saves optical fiber resources, supports automatic service provisioning and protection switching, provides visibility into optical fiber quality, and enables accurate fault locating.
Semi-active WDM: Passive colored optical modules and multiplexer/demultiplexer units are deployed on the AAU side, and active WDM devices are deployed on the BBU side.
* 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.
