GIGABIT ETHERNET PASSIVE OPTICAL NETWORK HAVING DOUBLE LINK STRUCTURE AND DOUBLE LINK SETTING METHOD USING THAT

摘要

Gigabit Ethernet optical network is disclosed having a dual-link structure. Gigabit Ethernet optical network of the present invention, OLT, is composed of a plurality of optical couplers, and a plurality of ONU. The OLT in response to the registration request message is received via an optical cable to an active link and a standby link is set with respect to the one device. A plurality of optical coupler is disposed between OLT and ONU is connected to each other by a plurality of dual over different optical fiber cable. When a plurality of the ONU in response to having a structure associated with each of the OLT via an optical cable and a double one, each of registration request messages request the OLT receives a registration message from the active OLT forming an active link with the OLT and the optical fiber cable and, from the OLT When receiving the waiting message to form an air link via the OLT and the optical cable.
