Embodiment 1

[0029] see figure 1 , this embodiment provides an optical signal control method, the method comprising:

[0030] 101: Detect whether there is a circuit board pulled out from the optical backplane;

[0031] 102: If a circuit board is pulled out, query the sending ports of other circuit boards connected to the slot where the pulled out circuit board is located, and send a first control command to the sending port, and the first control command is used to notify the shutdown of the circuit board. The sending port may adjust the output power of the sending port to be below a preset threshold, where the preset threshold is a specified boundary value for distinguishing whether the sending port is in a working state.

[0032] In this embodiment, there are at least two data slots on the optical backplane, and the data slots include service board slots or switching board slots, one of which is the slot where the circuit board to be pulled out is located, and the other or more It is t...

Embodiment 2

[0045] see figure 2 , this embodiment provides a method for controlling an optical signal, which is controlled based on an in-position detection signal, and the method includes:

[0046] 201: Detect the presence detection signal on the optical backplane.

[0047] 202: Judging whether the presence detection signal is the specified first level, if the presence detection signal is the specified first level, then execute 203; if the presence detection signal is the specified second level, then Execute 204.

[0048] Wherein, the specified first level is a high level, and the second level is a low level; or, the specified first level is a low level, and the second level is a high level.

[0049] 203: Determine that a circuit board has been pulled out from the optical backplane, query the sending ports of other circuit boards connected to the slot where the pulled out circuit board is located, send the first control command to the sending port, and notify to close the sending port...

Embodiment 3

[0072] see Image 6 , this embodiment provides an optical signal control system, the system includes:

[0073] A detection module 601, configured to detect whether a circuit board is pulled out from the optical backplane;

[0074] The control module 602 is used for if the detection module 601 detects that a circuit board is pulled out, then query the sending ports of other circuit boards connected to the slot where the pulled out circuit board is located, and send a first control instruction to the sending port, the The first control instruction is used to notify to close the sending port or adjust the output power of the sending port to be below a preset threshold, where the preset threshold is a specified boundary value for distinguishing whether the sending port is in a working state.

[0075] In this embodiment, there are at least two data slots on the optical backplane, and the data slots include service board slots or switching board slots, one of which is the slot wher...

Abstract

The invention discloses an optical signal control method, an optical signal control system and an optical back plate system, belonging to the technical field of optical communication. The method comprises the steps of: detecting whether a circuit board is drawn out from an optical back plate or not; if so, inquiring sending ports of other circuit boards connected with a slot position of the drawn-out circuit board, and sending a first control instruction to the sending ports to notify the closing of the sending ports, or regulating output powers of the sending ports to be below a preset threshold. The optical signal control system comprises a detecting module and a control module. The optical back plate system comprises the optical signal control system. In the invention, the optical signal leakage of an optical connector in the slot position of the drawn-out circuit board is prevented; the harm to operators, specifically the eyes of the operators, is avoided; and the system power consumption is reduced.

Description

technical field [0001] The invention relates to the technical field of optical communication, in particular to an optical signal control method, an optical signal control system and an optical backplane system. Background technique [0002] The circuit board refers to the printed circuit board inserted into the slot of the backplane, and usually includes: service board, switch board and main control board. Among them, the service board inserted in the service slot of the backplane is called the service board, the switch board inserted in the switch slot of the backplane is called the switch board, and the main control board inserted in the main control slot of the backplane. The switch board contains a switch chip. In the centralized switching system, the data signals on other circuit boards except the switch board will be connected to the switch chip of the switch board, so as to realize the data exchange between the slots; In the interconnected system, the data of each se...
