    ONU(광 노드 유닛)_타입 IV

    ∙ The TFO-ONU-C-870B is TFO’s latest generation 870MHz optical node Platform. This platform allows a maximum value node for service provider who are looking for the fiber deeper into new and current HFC network. The TFO-ONU-C-870B offers the flexibility to function as a single output node in fiber deep architectures. The TFO-ONU-C-870B is the perfect solution for increasing bandwidth and revenues with limited capital expenditures. 1550nm region CWDM return transmitters allows system operators to maximize the benefit of reduced number of return path fiber cables. The standard features include 15Amps power passing capability, Crowbar surge protection and plus the deeper lid contain a fiber tray plus, option module of the Network Monitoring transponder.
