The Calnex A100 was designed with SyncE in mind and supports both SyncE pass-thru and synchronisation to external clock references, as well as the 25GbE and 10GbE interfaces that fronthaul requires. The Calnex A100 can also filter on, and impair, specific eCPRI and RoE message types thereby helping engineers understand how eCPRI and RoE behave in a real fronthaul network.
