FULL BAND UNI-DIRECTION HYBRID FIBER AND COAXIAL

摘要

Full band one way hybrid fiber coaxial according to the present invention comprises a headend having a network management system and a spectrum analyzer; a downstream optical network unit having an optical receiver connected to the headend by an optical cable and a full band amplifier connected to the optical receiver; a trunk bridge amplifier connected to the downstream optical network unit and having a full band amplifier; and an upstream optical network unit connected to the trunk bridge amplifier and having an optical transmitter and a full band amplifier, wherein the downstream optical network unit can transmit a signal in the same way as the trunk bridge amplifier and the upstream optical network unit. By this construction, the present invention may use frequencies for all the bands and assign channels irrespective of upstream and downstream.
