Passive optical network system and method of optical routing device and application optical routing device

Abstract

The invention discloses an optical route device, which can output the input optical signal with different wavelength at arbitrary output end, and it includes: uniting / splitting wave device, which is used to unite and split the received optical signal; several splitters, and one port connects with several second uniting / splitting wave devices, which is used to distributing / combining the received optical signal; and routing device, connects with ports of several splitters, which is used to switch between the different output ports, and the optical signal can be sent to any output ports. The invention also discloses wireless optical network system and method which use the optical route device. Using the invention, it can realize the general purpose of optical network unit, and it is convenient for providing service for vendor.

Description

technical field [0001] The present invention relates to a passive optical network system, and more specifically, the present invention relates to a passive optical network system, which can arbitrarily route optical signals of different wavelengths to any colorless optical network unit. Background technique [0002] At present, many Internet services are accessed through dial-up modems, asymmetric digital line subscriber lines (ADSL), cable modems (CM), VDSL, etc. with rates ranging from 56K to several megabytes. However, in order to provide various services, such as high-quality video information services, VoD (Video on Demand) services, etc., data transmission requires a bandwidth of about 100 Mbps, and the above-mentioned access methods cannot meet the requirements. Therefore, The demand for laying access networks with optical fibers is growing rapidly. The Passive Optical Network (PON) is a user access network that can meet these new service requirements and is economica...

Problems solved by technology

[0009] Since the uplink and downlink wavelength pairs of ONUs of different operators are not uniform, when users choose different operators, they need to replace ONUs, which brings a lot of trouble to users and virtually limits the freedom of user choice;

[0010] Because the operator may lease different wavelength pairs in different cells, the operator must stock multiple types of ONUs, which increases the inventory burden of the operator and limits the service distribution of the operator;

[0011] Since terminal manufacturers need to produce various types of ONUs, the total amount of mass production of various types of ONUs is limited, which is not conducive to the reduction of ONU costs
