Description

technical field [0001] The present invention relates to the communication field, in particular to a device and method for supplying power to a 300PIN 40Gb optical module. Background technique [0002] The 300PIN 40Gb optical module agreement "REFERENCE DOCUMENT FOR300PIN 40Gb TRANSPONDER" requires that the single board can provide Adaptable Power Supply (APS for short) for the 300PIN 40Gb optical module, and the voltage range of APS is 1.2V~2.5V. This agreement gives the connection block diagram of APS and optical module, such as figure 1 As shown in A. According to the agreement, the pins between APS and 300PIN optical module include 4 signals, namely APS_Digital, APS SENSE, APS SET and GND. APS_Digital is used to supply power to the optical module, APS SET sets the adjustment point of the APS output voltage, and the APS SENSE signal provides remote sensing for the output voltage APS POWER. Correspondingly, there are 4 pins between the APS and the 300PIN optical module, ...
