FHM Specification Sheet
Onyx Fronthaul Multiplexer
The GXC Onyx Fronthaul Multiplexer (FHM) is a high-performance, versatile open networking device designed to expand coverage and maximize FU resources with flexibility as service providers improve their services by:
Extending service coverage while minimizing DU resources needed by grouping RUs into virtual cells
Cascading up to 8 FHMs (future)
Compensating for various fiber length delays
Supporting full SyncE and IEEE 1558 v2 (T-TC)
