Embodiment Construction

[0063] In order to make the object, technical solution and beneficial effect of the present invention clearer, the present invention will be further described in detail below in conjunction with the embodiments and accompanying drawings.

[0064] In the passive optical network system and its optical path processing method provided by the present invention, in the downlink data processing process, the output optical paths of the central end equipment of TDM-PON and the central end equipment of WDM-PON are merged through filtering and optical path connection units, and then passed through The optical branching and filtering unit sends the combined optical paths to the TDM-PON user terminal and the demultiplexer / multiplexer connected to the WDM-PON user terminal after branching and / or filtering. In the process of uplink data processing, the output optical path of the TDM-PON user terminal and the demultiplexer / multiplexer connected to the WDM-PON user terminal is combined through ...

Abstract

The invention discloses an inactive optical network system and a relative optical path processing method, wherein in descending data process, the invention uses filter and optical path connector to combine the output paths of central devices of TDM-PON and WDM-PON, via beam divider and filter unit to be divided and/or filtered to be sent to a TDM-PON user terminal and a splitting/combining device, and in ascending data process, the invention uses the beam divider and filter unit to combine the output optical paths of the TDM-PON user terminal and the splitting/combining device, and via a filter and optical path connector, the combined optical path is divided and/or filtered to be sent to the central devices of TDM-PON and WDM-PON. The invention realizes the coexistence of TDM-PON system and WDM-PON system, to avoid resource waste caused by upgrading TDM-PON user terminal to WDM-PON user terminal.

Description

technical field [0001] The invention relates to passive optical network technology, in particular to a passive optical network system and an optical path processing method thereof. Background technique [0002] In the current communication services, the development of video services, especially Internet TV (IPTV) services, causes a sharp increase in communication traffic, which puts forward a higher demand for bandwidth. At present, the data transmission of communication services mainly adopts the digital subscriber line (XDSL) technology, but the XDSL technology cannot meet the bandwidth requirements of high-definition television (HDTV). [0003] In order to meet the increasingly high bandwidth requirements of communication services, Passive Optical Network (PON) is used as the access network in the communication network. [0004] The existing passive optical network is divided into time division multiplexing passive optical network (TDM-PON) and wavelength division multip...
