Patent ID: 8064477

Claim:
A multi-channel provision system for a wired network, comprising: a tap-off unit for dividing a frequency band, assigned to a wired network for network communication, and providing resultant frequency bands to respective subscriber units belonging thereto; an optical network device disposed at a node where one or more sectors, divided according to a number of subscriber units that enable network access through the wired network, branch off, the optical network device providing a frequency band for network access to each sector so that a same frequency band is assigned to each sector, thus generating a multi-channel for the frequency band, and reusing the frequency band, assigned to the wired network, a number of times corresponding to the number of the sectors through generation of the multi-channel, wherein the optical network device comprises: one or more channel cards mounted on a motherboard having a bus, the one or more channel cards corresponding to the one or more sectors and adapted to provide the same frequency band to each sector, thus generating the multi-channel for the frequency band; and a media converter for processing signal conversion between an optical network and the motherboard; and at least one repeater disposed between the optical network device and each of the subscriber units, the repeater amplifying intensity of network packet signals, thus increasing possible communication distance between the optical network device and the subscriber unit.
