Abstract

The training control method and optical module provided in this application include: querying whether the training status control command flag is a first preset command value; if it is the first preset command value, then causing the laser driver to transmit a second electrical signal sent by the host computer to a limiting amplifier, so that the limiting amplifier transmits the electrical signal back to the host computer via a gold finger, wherein the host computer is the host computer to which the optical module is connected. When the training status control command flag in the optical module is the first preset command value, the training control method and optical module provided in this application control the optical module to enter training mode, causing the laser driver to transmit an electrical signal to a limiting amplifier, and then transmitting the electrical signal back to the host computer via a gold finger. This effectively reduces jitter accumulation during electro-optical conversion and transmission, and assists in accurately assessing the degradation of electrical signals from each port on the system board to the MAC chip.
