Description
Technical field
The present invention relates to optical communication technique field, be specifically related to a kind of novel bi-directional light point add/drop multiplexer.
Background technology
Light point add/drop multiplexer (OADM) is all had place to show one's prowess in long distance line and metropolitan area network.In main line application, light point add/drop multiplexer is the preferred unit that has the intermediate node of upper and lower business.The information that optical add/drop multiplexer allows the different wave length signal of different optical-fiber networks only need to download at node in different place add drop multiplex is sent into treatment facility (comprising ATM switch, SDH switch and ip router), and do not need the information of this node processing directly by optical channel, from this node, to be passed through, thereby greatly improve the efficiency of node processing information, having overcome electric treatment node must wrap the shortcoming of processing to the IP of all arrival.
Traditional bi-directional light is divided add/drop multiplexer, and as shown in Figure 1, its elementary cell comprises 3 WDM(dense wave division multiplexers) module and 11 × 2 optical switch.The inside of the one WDM module and the 2nd WDM module includes 3 WDM devices, and the output of 2 WDM devices is and is connected on 2 inputs of the 3rd WDM device, and 2 WDM devices are λ
iand λ
jseparate wavelength-division, then through the 3rd WDM device, these two wavelength are combined and transfer to 1 × 2 optical switch.By 1 × 2 optical switch, select the λ of output A input or B input
iand λ
jlight signal.The 3rd WDM module comprises 2 WDM devices, and the input of 2 WDM devices is on 2 outputs that are connected in 1 × 2 optical switch in parallel, and its effect is the λ of 1 × 2 optical switch output
iand λ
jlight signal is divided into two-way transmission.But because traditional bi-directional light point add/drop multiplexer has been used 8 WDM devices simultaneously, therefore its insertion loss is large, system reliability is low.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of novel bi-directional light point add/drop multiplexer, and it can effectively reduce the insertion loss of OADM, improves the reliability of system.
For addressing the above problem, the present invention is achieved by the following technical solutions:
