Embodiment 1

[0052] This embodiment is a pure optical intersecting system board, applying large intersecting capacity and large granularity intersecting.

[0053] Such as Figure 4 As shown, the client-side part of the service board receives service signals of various types and rates accessed by the client, and after relevant processing on the client-side, it is connected to the optical cross-connect backplane through an optical connector. Such as Figure 4 1-1 signal in .

[0054] The optical cross-connect board completes the crossing of optical signals from the optical cross-connect backplane, and the cross-connected optical signals are connected to the optical cross-connect backplane through optical connectors.

[0055] These cross-over optical signals will be sent to the optical transmission line through multiplexing and optical amplification on the line side of the service board. Such as Figure 4 1-2 signal in.

[0056] The above three steps are completed from the client-side ac...

Embodiment 2

[0062] In this embodiment, the optical cross-connect boards are 1+1 for service protection, and dual sending and optimal receiving are implemented on the service boards.

[0063] Such as Figure 5 Shown:

[0064] Dual transmission: The service board is installed with a 50 / 50 optical splitter, and the optical signal processed by the client side of the service board is divided into two channels through the 50 / 50 optical splitter on the service board and connected to the optical cross-connect backplane through the optical connector. The optical linkers on one side of the cross-connect board are respectively connected to the optical cross-connect board 1 and the optical cross-connect board 2 . Cross-connect board 1 and cross-connect board 2 perform the same cross-connect operation on the double-sent signal.

[0065] The cross-connect board 1 and the cross-connect board 2 respectively send the crossed two-way optical signals to the service board through the optical connector and ...

Embodiment 3

[0068] In this embodiment, for the 1+1 protection of the optical cross board, dual transmission is implemented on the optical cross board backplane, and service protection is realized by using the active / standby switchover of the optical cross board.

[0069] Such as Figure 6 Shown:

[0070] Dual transmission: The optical signal processed on the client side of the service board is connected to the optical cross-connection backplane through the optical connector. The signal is divided into two, that is, the 50 / 50 optical splitter divides the optical signal into two channels and connects them to the optical cross-connect board 1 and the optical cross-connect board 2 respectively through the optical connector. Cross-connect board 1 and cross-connect board 2 perform the same cross-connect operation on the double-sent signal.

[0071] Cross-connect board 1 and cross-connect board 2 are mutually active and standby optical cross-connect boards.

[0072] Cross-connect board 1 and ...

Abstract

The invention provides a light signal cross system, and a cross processing method and device. The system comprises a business board and a cross board which is used for the cross processing of a light signal. The system also comprises a backlight plate, a first optical connector, and a second optical connector. The backlight plate is connected with the cross board through the first optical connector, and is used for transmitting the light signal from the business board to the cross board through a light path. The business board is connected with the backlight plate through the second optical connector. Through the above technical scheme of the invention, the system solves a technical problem in related technologies that an electric signal cross scheme cannot adapt to a single-slot ultrahigh speed or bandwidth cross capacity, and provides powerful support for a single-slot business board employing larger cross bandwidth.

Description

technical field [0001] The invention relates to the field of optical communication, in particular to an optical signal cross system, cross processing method and device. Background technique [0002] With the development of telecom networks towards packetization and broadband, All-IP has become the evolution trend of service networks. How to carry IP services efficiently while reducing network construction and operation and maintenance costs has become the most concerned concern of operators in the construction of transmission networks. question. The transport network not only requires broadband transport, but also requires high survivability, flexible configuration, flexible scheduling of wavelengths and services, and smooth expansion to meet the effective carrying of IP services. However, with the further increase of network capacity and the gradual evolution of the network into a Mesh complex network, the capacity requirements related to core node business scheduling are ...
