EOC Head Equipment

La description

FHC***1 system is a active EOC equipment which is based on HFC network Bidirectional transformation technic and realize the broadband data access. It adopts the HomePlug AV standard and uses digital modulation demodulation technology. FHC***1 system features: High concurrent number of users One head facility can carry *3 concurrent users, it also can be upgraded to **7 and according to request, this fully satisfies the demand about the concurrent number of users. High bandwidth The Physical layer transmission bandwidth is up to **0Mbps. It can provide effective **0Mbps bandwidth for all users connected the head facility. That fully satisfies the family users’ demand on all broadband business application. High anti-jamming FHC***1 system adopts OFDM (Orthogonal Frequency Division Multiplexing), FEC ( Forward Error Correction) and channel auto-negotiation technic. Every carrier wave frequency can choose close up or turn on. That can avoid interference coming from the broadcasting station and radio. Small rebuilding work Regarding the current HFC network, besides it is needed to bridge with duplex fiter where there requires single unidirection amplifier, and no need make transformation on other line. As long as install according FHC***1 facility, it will realize data broadband access and then achieve the directional rebuilding.
