Optical modules for network communication equipment testing

Abstract

The invention discloses an optical module for testing network communication equipment, which comprises: a micro control unit; a signal regeneration unit, which is electrically connected to the micro control unit, and the signal regeneration unit is connected to the micro control unit through an electrical interface to the device under test; wherein, the signal regeneration unit receives the test signal sent by the device under test through the electrical interface, and sends the test signal to the device under test through the electrical interface after limiting and amplifying; The micro control unit receives the control signal from the device under test through the electrical interface, and monitors the signal regeneration unit in real time based on the control signal. The optical module of the present invention is specially used for testing network communication equipment such as switches, which simplifies the optical link components of traditional optical modules, greatly reduces production costs, and is also compatible with 100M, 1000M and 10000M speeds. There is no need to plug and unplug the optical fiber, and the data loopback can be realized directly, with the functions of data regeneration and signal equalization.

Description

technical field [0001] The invention relates to an optical module. More specifically, the present invention relates to an optical module used for testing network communication equipment such as switches and routers. Background technique [0002] The optical module is an integrated communication accessory that provides photoelectric-to-optical conversion capabilities. It supports SONET, GigabitEthernet, Fiber Channel (Fiber Channel) and some other communication standards. It is widely used in backbone networks, metropolitan area networks, access networks, and data centers. And other markets with communication needs. Its packaging forms include GBIC, SFF, SFP, XFP, QSFP, CFP, etc. [0003] As the lowest component of the communication protocol (media-related layer), the optical module cannot be used alone, and must be used in conjunction with the switch device. At the same time, the optical module is also an important accessory of the switch equipment. Manufacturers who pro...

AI Technical Summary

Problems solved by technology

[0009] ① Due to different optical module manufacturers, the power consumption value cannot reach or approach the rated value of the switch protocol, and it is difficult to verify the power drive capability of the switch;

[0010] ② Gigabit and 10 Gigabit optical modules cannot be used universally, and the data rates are not compatible with each other, resulting in a doubled increase in the number and types of optical modules used for testing;

[0011] ③ Ordinary optical modules have no indicator lights and other designs, so it is impossible to obtain the status of optical modules intuitively and quickly

[0016] ①It cannot indicate the signal loss, that is, it cannot provide the LOS signal indication of the software and hardware; ②Due to the passive coupling, the signal will not be regenerated, so it is equivalent to doubling the length of the printed circuit board signal line of the switch equipment, which will cause great damage. The attenuation of the signal leads to serious degradation of the signal, which cannot be used for 10 Gigabit communication tests; ③ cannot handle the Tx-disable signal; ④ cannot provide the signal squelch function of the receiving end; ⑤ Due to the existence of ①③, the module cannot simulate the conventional optical module The monitoring function will cause large differences in use, and cannot achieve the purpose of communication testing of the switch
