Pin, the i.e. corresponding controlling switch of optical module low-power consumption mode, specifically, optical module is normal when the input of the pin is low level
Work, in this operating mode, it is impossible to tackle the main frame of high power consumption module；When input is high level, the entirety of optical module
Power consumption can be reduced to below 1.5W, in this operating mode, and the serial line interface and laser of optical module can be with safe operations
And support the execution of reset interrupt.
In addition, in the case where second pin has Intl function, the corresponding pin name of second pin is Intl, should
Pin is output pin, for when optical module has any alarm, exporting high level.However, for specific warning information still
Iic bus is needed to be transmitted.
In this case, the optical module described in the disclosure can be the serial optical modules of QSFP.In addition, described in the disclosure
The one or more that QSFP series optical modules can include but is not limited in QSFP, QSFP+, QSFP28, QSFP56.
S30. analyze the pinout information comprising the second information when, will first pin configuration for
Disable function and the second pin is configured to the function with Los.
After MCU is analyzed the pinout information of acquisition in step slo, MCU may determine that whether pinout information wraps
Containing the second information, and when judging that pinout information includes the second information, MCU can be corresponding with the second information by performing
Pin defines program and is the function with Disable by the first pin configuration and second pin is configured into the function with Los.
Wherein, Disable function is：When input high level, laser is closed.In addition, the function of Los function is：Work as optical mode
During the receiving side no signal of block, a cue is exported.
With reference to Fig. 2, the first pin may, for example, be pin 31 (Pin 31), and second pin may, for example, be the (Pin of pin 28
28).Specifically, in the case where the first pin has Disable function, the corresponding pin name of the first pin is
Disable, in addition, in the case where second pin has Los function, the corresponding pin name of second pin is Intl.
In this case, optical module can be SFP+ optical modules.
, can be with optical module by the power and energy with the serial optical modules of QSFP in order to preferably introduce the advantage of the disclosure
To be illustrated exemplified by the function with SFP+ optical modules.
First, a host computer writes the above-mentioned first information in the default register of the optical module of the disclosure, optical module
MCU is by obtaining the first information and the optical module is configured to the serial optical modes of QSFP by execution program corresponding with the first information
Block.
If next, the optical module of the disclosure is applied in some long-distance transmissions application scenarios, when for example needing
, can not in sequential so can produce due to there is no function in now optical module to close the pin of laser when closing laser
The problem of satisfaction is required.In consideration of it, the host computer in this application scenarios can send second into the default register of optical module
Information, the MCU of optical module can by obtain the second information will perform LPMODE function the first pin functional mapping into
Disable function, at the same time, due to the limitation of protocol requirement, the function of performing the second pin of Intl function becomes
Change Los function into.
