Problems solved by technology

[0003] During the power-on process of the optical module, the MCU working state of the optical module is uncontrollable, and an uncontrollable signal is generated, and the level of the I2C signal line is temporarily pulled down by the uncontrollable signal, such as Image 6 The levels of the SDA signal line and the SCL signal line shown are all pulled down, which affects the normal communication of other optical modules mounted on the I2C signal line
It can be seen from the above that during the power-on process of the optical module, the I2C signal will be pulled down, which will affect the normal communication of other module products

Abstract

The optical module comprises a circuit board, an MCU and a golden finger, the surface of the circuit board is provided with an SDA signal line and an SCL signal line, a power supply slow start circuit is arranged between the golden finger and an MUC power supply pin, an SDA slow start circuit is arranged between the golden finger and an SDA interface, and an SCL slow start circuit is arranged between the golden finger and an SCL interface. The power supply slow start circuit is electrically connected with the SDA slow start circuit and the SCL slow start circuit. The SDA slow start circuit and the SCL slow start circuit respectively conduct the SDA signal line and the SCL signal line in a delayed mode after receiving a power supply slow start circuit signal, the conduction time of the SDA signal line and the SCL signal line is controlled through the SDA slow start circuit and the SCL slow start circuit, then the corresponding SDA signal line and the SCL signal line are conducted in a delayed mode, the I2C signal line is conducted in a delayed mode, and therefore the I2C signal line is switched on in a delayed mode. And the level of the I2C signal is prevented from being lowered in the power-on process of the optical module, so that normal communication is ensured.

Description

technical field [0001] The present application relates to the technical field of optical communication, and in particular to an optical module. Background technique [0002] Information can be transmitted between the optical module and the host computer through the I2C signal line. The I2C signal line includes the SDA signal line and the SCL signal line, where the SDA line is the data line and the SCL line is the clock line. [0003] During the power-on process of the optical module, the MCU working state of the optical module is uncontrollable, and an uncontrollable signal is generated, and the level of the I2C signal line is temporarily pulled down by the uncontrollable signal, such as Figure 6 The levels of the SDA signal line and the SCL signal line shown are all pulled down, thereby affecting the normal communication of other optical modules mounted on the I2C signal line. It can be seen from the above that during the power-on process of the optical module, the I2C sig...
