Problems solved by technology

[0005] The technical problem to be solved by the present invention is that the existing multicast optical switch generally does not have an active communication function, and the communication mainly uses an OSC configured separately, and the OSC is transmitted in the optical fiber as an independent wavelength channel, and the Each receiving end is extracted and sent to the host for processing. It is necessary to configure an independent OSC unit for each optical add-drop multiplexer, which increases the cost and failure rate; moreover, the parameters of the OSC unit are fixed and the configurability is poor.

Embodiment 1

[0044] Embodiment 1 of the present invention provides a multicast optical switch supporting the line ID function, such as figure 1 As shown, it includes a conventional multicast optical switch, an optical transceiver module with a line ID calibration function, and a processing module. Among them, the conventional multicast optical switch is a multicast optical switch in the prior art, and usually has the capability of adding wave and downwave functions on both sides, where the concept of upwave is to upload the local optical signal to the main optical path, and the concept of downwave is to downlink the optical signal in the main optical path to the local; and, in the embodiment of the present invention, it can realize In the solution, the conventional multicast optical switch can be pre-cured switch channels, or can support dynamic adjustment of switch configuration during use. The optical transceiver module with the line ID calibration function can be understood as being abl...

[0061] The embodiment of the present invention also proposes a method for implementing a multicast optical switch component supporting the line ID function, using the multicast optical switch component supporting the line ID function as described in Embodiment 1, such as Figure 5 As shown, the methods include:

[0062] In step 201, the first multicast optical switch newly added to the system interacts with the management server of the multicast optical switch through the processing unit set in the first multicast optical switch to complete the monitoring of all lines involved in the system Collection of ID information.

[0063] Wherein, the above-mentioned process of "the processing unit set in the first multicast optical switch interacts with the management server of the multicast optical switch to complete the collection of all line ID information involved in the system" may be during the processing The first thing a unit does when it is powered on for the first time and h...

Abstract

The invention relates to the technical field of optical communication, and provides a multicast optical switch assembly supporting a line ID function and an implementation method thereof. When the multicast optical switch is used on a lower wave side, the input end of the transceiver module is coupled with each input end of a lower wave in the multicast optical switch through a wave separator; when the multicast optical switch is used on an upper wave side, the output end of the transceiver module is coupled with each output end of an upper wave in the multicast optical switch through a combiner; a filter is arranged between the wave separator and the transceiver module, and the filter is used for filtering out line ID signals from optical signals separated from each input end of the multicast optical switch. When the device disclosed by the invention is used for configuring the wavelength division multiplexing transmission system, the complexity of manual configuration can be simplified, and the configuration accuracy can be improved. And the efficiency of updating the system and overhauling the system is greatly improved.

Description

【Technical field】 [0001] The invention relates to the technical field of optical communication, in particular to a multicast optical switch component supporting the line ID function and a realization method thereof. 【Background technique】 [0002] In an existing optical wavelength division multiplexing system, a multicast optical switch is widely used at each reconfigurable optical add-drop multiplexer (Reconfigurable Optical Add-Drop Multiplexer, abbreviated as: ROADM) site. During site configuration, many connections need to be configured, and the connection relationship between each optical add-drop multiplexer is relatively complicated. In order to manage and configure the connections of each optical add-drop multiplexer, the communication between them is extremely important Features. [0003] Existing multicast optical switches generally do not have an active communication function, during which the communication mainly uses a separately configured Optical Supervisory ...
