Problems solved by technology

[0004] However, if the optical module fails, it needs to be replaced with a new optical module
The optical module needs to go through the initialization process from power-on to system startup. The initialization process takes about 3 minutes. During this 3-minute period, the communication service will be interrupted.

Abstract

The embodiments of the present application illustrate an optical module and a method for controlling the optical module. According to the technical solution shown in the embodiment of this application, when the main network element equipment fails, the external device directly sends a high-level control command to the standby MCU of the optical module. At this time, the standby MCU of the optical module directly controls the standby laser driver to turn on, and the standby laser The driver drives the backup laser diode to emit light. Before the external device sends a high-level control command to the backup MCU, the backup MCU is always in a standby state. When the backup MCU receives a high-level control command, it can directly control the backup laser driver to start. , this process does not go through the initialization process, therefore, there is no interruption of the communication service.

Description

technical field [0001] The embodiments of the present application relate to optical communication technologies. More specifically, it relates to an optical module and a control method of the optical module. Background technique [0002] In the field of optical communication technology, optical fiber network systems are widely used. The optical fiber network system consists of OLT (Optical Line Terminal), ONT (Optical Network Terminal) and optical distribution network. Among them, the OLT device includes two parts: an optical module and an external device. Among them, the function of the optical module is photoelectric conversion. The transmitting end converts the electrical signal into an optical signal, and after transmission through the optical fiber, the receiving end converts the optical signal into an electrical signal. [0003] figure 1 It is a schematic diagram of the optical module structure, such as figure 1 The exemplary optical module 100 may include a transm...
