AI Technical Summary

Technical Problem

The power consumption of the driver in the LPO optical module is high, resulting in waste of energy.

Method used

The control circuit is used to control the on/off of the current source of each channel separately, and the low-power mode control of each channel is realized according to the size of the input signal, so that channels without input signals or with very low input signals automatically enter the low-power mode.

Benefits of technology

Reduces power consumption of the driver, avoids waste of energy, and realizes the reuse of the driver at different rates, reducing procurement costs.
