While a logical order is shown in the flow chart, in some cases, the steps shown or described may be performed in an order different than that shown.
In this embodiment, the optical port rate adaptive method includes:
step S10, when detecting that the optical module is installed at the optical fiber port of the optical fiber switch, acquiring a preset speed value;
in this embodiment, in the current internet era, optical modules and optical fiber switches are not separated from enterprise network deployment and data center construction. The optical module is mainly used for converting an electric signal and an optical signal, and the optical fiber switch plays a role in forwarding the optical signal. The optical module is composed of an optoelectronic device, a functional circuit, an optical interface and the like, wherein the optoelectronic device comprises a transmitting part and a receiving part. In brief, the optical module functions as a photoelectric converter, the transmitting end converts an electrical signal into an optical signal, and the receiving end converts the optical signal into the electrical signal after the optical signal is transmitted through the optical fiber. In the field of general optical fiber switches, such as digital communications and transmission, in fact, an optical fiber switch with an optical port and an optical fiber switch with an optical module are both referred to as supporting an optical module interface, and only different terms are used.
When in communication, the optical fiber switch and the optical module which are connected with each other are required to have uniform optical port rate and mode so as to normally communicate. As described above, in the prior art, the optical fiber switch needs to obtain the type and the working mode of the optical module by reading chip resources of the EEPROM inside the optical module, and then configure a register built in the optical fiber switch to update the optical port rate of the optical fiber switch. In practical use, due to the difference between the chip architecture and the internal register of the optical fiber switch, the optical port rate needs to be adjusted during the practical development of the optical fiber switch manufacturer, and the above operations need to be performed for each optical fiber switch chip: the work of reading the optical module EEPROM and configuring the chip register of the optical fiber switch is extremely complicated and time-consuming, and the debugging is required by an optical fiber switch manufacturer and a chip manufacturer. According to the method and the device, the optical port rate of the optical fiber switch is configured in a polling mode, and the target optical port rate corresponding to the optical fiber port of the optical fiber switch is determined according to the communication state of the optical fiber switch and the optical module. Therefore, reading of the built-in EEPROM of the optical module is avoided, configuration complexity is reduced, and configuration efficiency is improved. The polling method of the present application is versatile and is not limited to any optical fiber switch or any optical module.
Specifically, an optical fiber interface of the optical fiber switch is provided with an LOS pin, whether an optical fiber is inserted into the optical fiber interface is detected through the LOS pin, one end of the LOS pin is connected with a chip of the switch, and therefore whether the optical fiber interface is output is determined through the chip. After the optical fiber switch is powered on, whether the optical module is plugged in the optical fiber port is detected by inquiring the LOS pin.
Specifically, step S10 includes:
in step S11, a speed value is obtained from the preset speed value list as a preset speed value.
In this embodiment, when it is determined that an optical module is installed in an optical fiber port of an optical fiber switch, an optical port rate of the optical fiber switch is configured by polling, and a preset rate value is first obtained as the optical port rate. The preset speed value can be obtained from a preset speed value list, common optical modules are SFP, SFF, SFP +, GBIC and XFP, wherein a gigabit optical module is mostly an SFP optical module, and a gigabit optical module is mostly an SFP + optical module, so the speed values in the preset speed value list include 1000Mbps, 100Mbps and 10 Gbps.
Step S20, configuring a register corresponding to the optical fiber port, and setting the optical port rate corresponding to the optical fiber port of the optical fiber switch as a preset rate value;
in this embodiment, the optical port rate corresponding to the optical fiber port is updated by configuring a register of the optical fiber switch. Firstly, determining a register address corresponding to the optical interface rate, then updating the optical interface rate according to the register address, and setting the optical interface rate as a preset rate value.

step S32, when receiving the acknowledgment data fed back by the optical module, determining that the communication status is successful;
step S33, when the acknowledgment data fed back by the optical module is not received within a preset time, determining that the communication status is communication failure.
In this embodiment, the optical fiber switch sends negotiation data to the optical module, for example, the same negotiation data may be continuously sent for 3 times, and after the optical module successfully receives the negotiation data, confirmation data is sent to the optical fiber switch, where the confirmation data may also be consistent with the contents of the negotiation data. When the optical fiber switch receives the confirmation data fed back by the optical module, the optical fiber switch and the optical module have the same optical port rate, and the communication state is successful. Otherwise, when the confirmation data fed back by the optical module is not received within the preset time, the optical port rates of the optical fiber switch and the optical module are inconsistent at the moment, and the communication state is communication failure.
Step S40, when the communication state is determined to be communication failure, acquiring a new preset rate value, and updating the optical port rate corresponding to the optical fiber port of the optical fiber switch based on the new preset rate value;
in this embodiment, when it is determined that the communication state is a communication failure, which indicates that the optical port rates of the optical fiber switch and the optical module are not consistent at this time, the optical port rate of the current optical fiber switch needs to be updated, that is, a new preset rate value is obtained, a different preset rate value may be continuously obtained in the preset rate value list, then, a register of the optical fiber switch is configured to update the optical port rate corresponding to the optical fiber port, and the optical port rate is set to the new preset rate value.
Step S50, based on the updated optical port rate corresponding to the optical fiber port, when it is determined that the communication state between the optical fiber switch and the optical module is successful, taking the current optical port rate of the optical fiber port as a target optical port rate.
In this embodiment, the optical fiber switch sends the negotiation data to the optical module again, and after the optical module successfully receives the negotiation data, sends the confirmation data to the optical fiber switch, where the confirmation data may also be consistent with the contents of the negotiation data. When the optical fiber switch receives the confirmation data fed back by the optical module, the communication state is successful, which indicates that the optical fiber switch and the optical module have the same optical port rate, the current optical port rate of the optical fiber port is the target optical port rate, and the target optical port rate of the optical fiber port on the pair is recorded and stored. If the current communication state is still communication failure, step S40 is continuously executed until the optical port rate configuration is successful or an optical port rate configuration stop condition is detected. The optical port rate configuration stop condition may be that the maximum number of times of non-configuration is reached.
Further, in an embodiment, step S10 is preceded by:
step S60, when receiving the optical port rate configuration instruction, reading the port signal of each optical fiber port of the optical fiber switch;
step S70, determining whether each optical fiber port is provided with an optical module based on each port signal;
step S10 includes: when the port signal is a preset signal, determining that the optical module is installed at the optical fiber port corresponding to the port signal, and acquiring a preset rate value corresponding to the optical fiber port.
In this embodiment, the optical fiber switch includes a plurality of optical fiber ports, and can be connected to a plurality of optical modules, and when a port signal is a preset signal, it is determined that an optical module is installed at an optical fiber port corresponding to the port signal; optical port rate configuration may also be performed on the optical fiber ports connected to the optical modules in sequence.
Further, in an embodiment, after the step S30, the method further includes:
step S70, when it is determined that the communication state is successful, taking the current optical port rate of the optical fiber port as a target optical port rate, and storing the current optical port rate of the optical fiber port.
In this embodiment, the optical fiber switch sends negotiation data to the optical module, and after the optical module successfully receives the negotiation data, sends confirmation data to the optical fiber switch, where the confirmation data may also be consistent with the contents of the negotiation data. When the optical fiber switch receives the confirmation data fed back by the optical module, the communication state is successful, which indicates that the optical fiber switch and the optical module have the same optical port rate, the current optical port rate of the optical fiber port is the target optical port rate, and the target optical port rate of the optical fiber port on the pair is recorded and stored.
