Description

Technical Field

[0001] The present application relates to the technical field of communication equipment, and in particular to a power supply management method for a communication board and an optical module. Background Art

[0002] Optical communication equipment refers to communication equipment that uses light waves to transmit information. Among them, optical modules are interface devices of optical communication equipment, which are mainly responsible for sending and receiving signals.

[0003] Normally, when planning a communication system network, the needs of expansion and redundancy must be considered. Therefore, a large number of optical modules are installed on the communication boards of optical communication equipment, and some of the optical modules are often idle, resulting in no-load power modules responsible for power supply. Generally, the no-load loss of a single power module is greater than 0.5W, which is a huge waste of energy from the perspective of the entire communication system.

[0004] Therefore, how to avoid no-load power supply to optical modules, thereby improving unnecessary energy waste in optical communication equipment, is a technical problem that urgently needs to be solved. Summary of the invention

[0005] The purpose of this application is to provide a communication board and an optical module power supply management method, which can avoid the power module in the optical communication equipment from supplying power to the optical module without load, thereby improving the unnecessary energy waste of the optical communication equipment.

[0006] In order to achieve the above purpose, the embodiment of the present application is implemented as follows:

[0007] In a first aspect, a communication board is provided, comprising an optical module and a power module, wherein the communication board further comprises:

[0008] The control circuit is used to determine the optical module on the communication board that is in an idle state, and to control the power supply module to stop supplying power to the optical module in the idle state.

[0009] In a second aspect, a method for managing power supply of an optical module of a communication board is provided, wherein the communication board includes an optical module and a power module, and the method includes:

[0010] Determining the optical module on the communication board that is in an idle state; and,

[0011] The power module is controlled to stop supplying power to the optical module in an idle state.

[0012] The solution of the present application can actively detect the optical modules in idle state on the communication board, and once the optical modules in idle state are determined, the power module is controlled to stop supplying power to the optical modules in idle state according to the power-on and power-off logic of the power module, thereby improving unnecessary energy waste generated by optical communication equipment.

[0019] As mentioned above, existing optical communication equipment will configure a large number of optical modules on the communication board to meet the expansion and redundancy requirements of network planning, which results in some optical modules on the communication board being often idle and causing the power module to supply power without load. The power module's no-load supply is a meaningless waste of energy. From the perspective of the entire communication system, the problem is a small problem that can be seen in a big way.

[0020] To this end, the present application aims to propose an optical module power supply management solution that can prevent the power module in the optical communication equipment from supplying power to the optical module at no load, thereby improving unnecessary energy waste generated by the optical communication equipment.

[0021] In order to enable those skilled in the art to better understand the technical solutions in this specification, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are only part of the embodiments of this specification, not all of the embodiments. Based on the embodiments in this specification, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of this specification.

[0022] The embodiment of the present application provides a method for managing power supply of an optical module of a communication board, wherein the communication board includes an optical module and a power supply module for supplying power to the optical module. Figure 1 The figure is a flowchart of the optical module power supply management method, including:

[0023] S102, determining an optical module on a communication board that is in an idle state.

[0024] Specifically, in this embodiment, the optical module that is not connected to the communication board can be determined as being in an idle state, and the optical module that is connected to the communication board can be determined as being in a non-idle state.

[0025] As an exemplary introduction, this embodiment can detect whether the optical module is connected to the communication board in the following two ways.

[0026] Detection method 1: Determine whether the optical module is connected to the communication board through the level of the optical module's in-position pin.

[0027] Generally, the optical module will be connected to the communication board through its in-position pin (MOD_ABS pin). The in-position pin has different corresponding levels when it is not connected to the communication board and when it is not connected to the communication board.

[0028] Detection method 2: Determine whether the optical module is connected to the communication board by initiating access to the optical module.

[0029] For example, an access is initiated to the register of the optical module; if the optical module is connected to the communication board, a response signal will be fed back to the access; if the optical module is not connected to the communication board, no response signal will be fed back to the access.

[0030] S104, controlling the power supply module to stop supplying power to the optical module in the idle state.

[0031] The optical module reconnected to the communication board can be defined as being in a non-idle state. Correspondingly, this embodiment can control the power module to supply power to the optical module in the non-idle state.

[0032] It should be noted that how to control the power module to supply power to the optical module or stop supplying power depends on the power-on and power-off logic of the power module for the optical module in the circuit, which is not specifically limited in this document.

[0033] As an exemplary introduction, this embodiment can control whether the power module supplies power to the optical module by the level of the MOD_ABS pin of the optical module. That is, the MOD_ABS pin of the optical module defaults to a low level. When the optical module is connected to the communication board, its MOD_ABS pin is connected to the control circuit of the communication board, and one access end of the control circuit is pulled down to the bottom level; at this time, the control circuit controls the power module to supply power to the optical module according to the bottom level signal. Similarly, when the optical module is no longer connected to the communication board, its MOD_ABS pin no longer pulls the access end of the control circuit down to the bottom level; at this time, the access end of the control circuit returns to a high level to control the power module to stop supplying power to the optical module according to the high level signal.

[0034] The following introduces the power supply solution of the power module in combination with the specific implementation method.

[0035] Figure 2 It is a structural diagram of a communication board provided in an embodiment of the present application, including: an optical module 210 (at least one), a power module 220 (at least one) for supplying power to the optical module, and a control circuit 230.

[0036] Among them, the control circuit 230 is responsible for determining the optical module 210 in the idle state on the communication board; and, based on the level of the in-position pin of the optical module, controlling the power supply module 220 to stop supplying power to the optical module in the idle state and to supply power to the optical module 220 in the non-idle state.

[0037] Specifically, the power module 220 supplies power in the following two ways.

[0038] Power supply mode 1: one power module 220 is only responsible for supplying power to one optical module 210 , that is, the power module 220 and the optical module 210 in the communication board are in a one-to-one correspondence.

[0039] Power supply mode 2: one power module 220 is responsible for supplying power to at least two optical modules 210 , that is, each power module 220 in the communication board corresponds to at least two optical modules 210 .

[0040] For power supply mode 1

[0041] Take one of the corresponding power modules and optical modules as an example. Figure 3 The communication board shown in the figure. The control circuit in the communication board is provided with a first resistor R1 and a first transistor VT1 for each corresponding power module and optical module.

[0042] Among them, one end of the first resistor R1 is connected to the MOD_ABS pin of the corresponding optical module and the gate (hereinafter referred to as the G pole) of the corresponding first transistor VT1, and the other end of the first resistor R1 is connected to other power supplies VCC3V3_OTHER of the communication board (such as the power supply of complex programmable logic devices, clocks and other devices on the communication board); the drain of the first transistor VT1 (hereinafter referred to as the D pole) is connected to the enable pin (EN pin) of the corresponding power module, and the source of the first transistor (hereinafter referred to as the S pole) is connected to the ground pin (GND pin) of the corresponding power module.

[0043] When the optical module is plugged into the communication board, its MOD_ABS pin is pulled to GND by default. At this time, the G pole of the first transistor VT1 is pulled to the ground level, the first transistor VT1 is not driven and is not turned on, and the EN pin of the power module is suspended. At this time, the power module is turned on and outputs VCC3V3 to power the optical module.

[0044] When the optical module is no longer inserted into the communication board, the MOD_ABS pin begins to float. At this time, the VCC3V3_OTHER direct resistor R1 pulls the G pole of the first transistor VT1 to a high potential to turn on the first transistor VT1. After the first transistor VT1 is turned on, the EN of the power module is pulled to the ground through the first transistor VT1, and the EN pin level is low. At this time, the power module stops supplying power to the optical module. The VCC3V3 power supply on the communication board has no output by default. Only after the optical module is plugged in and the control circuit is used, can power be supplied.

[0045] For power supply mode 2

[0046] refer to Figure 4 The control circuit of the communication board shown in FIG. Assuming that a power module of the communication board is responsible for supplying power to n optical modules, the control circuit is provided with a second resistor R2, a second transistor VT2 and an AND gate D1 for each corresponding power module and optical module.

[0047] The input end of the AND gate D1 is respectively connected to the MOD_ABS pins of all corresponding optical modules; one end of the second resistor R2 is connected to the corresponding output end of the AND gate D1 and the G pole of the corresponding second transistor VT2, and the other end of the second resistor R2 is connected to the other power supply VCC3V3_OTHER of the communication board; the D pole of the second transistor VT2 is connected to the EN pin of the corresponding power module, and the S pole of the second transistor VT2 is connected to the GND pin of the corresponding power module.

[0048] When any target optical module is connected to the communication board, its MOD_ABS pin is pulled to GND and outputs a low level through the AND gate circuit. At this time, the G pole of the second transistor VT2 is pulled to the ground, the second transistor VT2 is not driven and cut off, and the EN pin of the power module is suspended. At this time, the power module outputs VCC3V3 to supply power to the target optical module.

[0049] When the target optical module is no longer inserted into the communication board, its MOD_ABS pin is left floating. At this time, VCC3V3_OTHER directly pulls the G pole of the second transistor VT2 to a high potential through the second resistor R2 to turn on the second transistor VT2. After the second transistor VT2 is turned on, the EN pin of the power module is pulled to the ground through the second transistor VT2, and the level of the EN pin is low. At this time, the power module stops supplying power to the target optical module.

[0050] In actual applications, the communication board is provided with at least two power supply slots for each power module, and each power module supplies power to the optical module inserted into its own power supply slot. For example, the serial number of the optical module is defined as mn according to the power module. Among them, m represents the mth power module, and n represents the nth slot corresponding to the mth power module. Among them, the first power module can supply power to optical modules 11, 12...1n; the second power module can supply power to optical modules 21, 22...2n; ...; the mth power module can supply power to optical modules m1, m2...mn.

[0051] In this embodiment, the optical module that needs to be connected to the communication board is preferentially inserted into the corresponding slot according to the sequence of the power modules. That is, the optical module is preferentially inserted into the slot of the first power module, and when the slot of the first power module is full, it is inserted into the slot of the second power module. The control circuit can power off the power module that is not inserted into the current power supply slot to maximize the reduction of the energy consumption of the communication board.
