Device for adjusting and measuring optical module

Abstract

The invention includes parts and operations: an optical module to be adjusted and measured carries out operations corresponding to received specific operation instruction; a computer in use for sending signal of adjusting and measuring instructions to the optical module to be adjusted and measured; a communication interface circuit for converting received signal of adjusting and measuring instructions to adjusting and measuring signals receivable by control unit, and sending the signals to the control unit; being composed of microprocessor and inner peripheral equipment, a control unit processes and interprets the received signals in order to create details operation instructions, which are sent to the optical module to be adjusted and measured through IIC bus. The invention implements debugging performance and calibrating monitored parameter automatically. Features are: debugging multiform optical modules supported, raised production efficiency and lowered cost.

Description

technical field [0001] The invention relates to an optical module commissioning device, which belongs to the technical field of digital optical fiber transmission systems. The invention can cooperate with other instruments to realize efficient commissioning of optical modules, and is suitable for research and development in digital optical fiber communication systems or digital optical fiber networks. production process. Background technique [0002] A large number of optical modules are used in the field of optical communication. With the rapid development of technology in the field of optical communication, higher requirements are put forward for optical modules in optical communication systems, and new types of optical modules emerge as the times require. [0003] These optical modules can not only be adjusted digitally, but also provide monitoring information about the optical modules. For example, received optical power, transmitted optical power, laser bias current, e...

Problems solved by technology

[0015] figure 1 The described method takes a lot of time to collect data, which is not conducive to improving production efficiency and reducing production costs

In addition, in the process of manually collecting and recording data, it is easy to make mistakes, resulting in inaccurate fitting coefficients

[0016] The method of using functional single boards for optical module debugging also has some disadvantages, including: the automatic calibration of optical modules cannot be realized, and the production efficiency is not high; the types of optical modules supported by each functional single board are very limited; the cost of functional single boards is relatively high. High, leading to an increase in the debugging cost of the optical module
