Wavelength division multiplexing passive optical network device

Abstract

The utility model provides a wave division multiplex passive optical network device, which comprises a central optical link terminal, a remote terminal node passive photosynthesis component wave unit and n optical network terminals. The central optical link terminal includes a optical retransmission unit and a photosynthetic component wave module; the optical retransmission unit completes retransmission service of which the rate is 10Gbps and further comprises n groups of the OTU modules; the remote terminal node passive photosynthetic component wave unit is a heat-insulated passive module which is used to complete the wave splitting of the forward wave length and the wave coupling of the retrograding wave length. The optical network terminal includes a group of OTU modules which is correspondent to the central optical link terminal, so as to jointly complete one information transmission between the central part and the terminal. As compared with the existing technology, the utility model realizes the 10 Gbps WDM PON for the individual user and improves the available bandwidth of the system. Meanwhile, the deficient transmission range is well solved, so as to achieve the long distance transmission with 10Gbps' WDM PON.
