Passive, 4G+5G Fronthaul 5G-MUX P2P Passive WDM with Fiber Monitoring for 4G/5G Fronthaul: Use existing passive optical network (for LTE, optic relay) without new investment for 5G Integration management for Passive Optical Network Solution


5G-MUX that is a smart MUX system, is composed of passive MUXs, line monitoring unit and line protection switching unit. 


Two passive MUXs are located at each different sites such as CO and RN. The line supervisor and line protection switch are installed in the 5G-PON COT system, and provide functions to monitor the status of the line and to provide sustainable service. 


5G-MUX not only utilize existing legacy fiber infra using CWDM sub-channel technology in O-band but also accommodate 8 channel per cell site.

5G-MUX is a member of the cost-effective and highly scalable Mobile Access
