Light path tester

Abstract

The invention relates to a light path tester, which comprises a shell body, a power supply device, a light signal display circuit, an optical module and a light receiving detection circuit, wherein the optical module is provided with a light input interface and an output level interface; the light receiving detection circuit is connected with the output level interface and the light signal display circuit; the power supply device supplies power to the optical module and the light receiving detection circuit; the optical module further comprises a light output interface and an input level interface for optical signal illumination; and the power supply device, the optical module and the light receiving detection circuit are all accommodated in the shell body. Compared with the existing optical tester, the light path tester adopts qualitative test and indicating lamp display to judge whether the optical signal exists or not, the requirements on test precision, test display and maintenance personnel quality are reduced, the manufacturing cost is far lower than the price of the existing optical tester, the requirement of light path detection can be satisfied, the maintenance cost and investment are also greatly saved, and furthermore, more economic benefit is produced.

Description

technical field [0001] The invention relates to network communication technology, in particular to an optical path tester applied to a passive optical network (Passive Optical Network, PON for short). Background technique [0002] With the rapid development of the Internet, network users' demand for network bandwidth is increasing day by day, and broadband users are not only satisfied with ordinary website browsing. The requirements of high-quality IPTV services for access bandwidth, user requirements for uplink speed, video conferencing, and high-speed downloads have gradually become mainstream applications. In order to meet the needs of the market, the core network of the communication network has undergone tremendous changes, while the traditional access network (the access network mainly refers to the network from the telecommunications room to the user end) that has been less changed has become the bottleneck of the entire network , various new broadband access technol...

Problems solved by technology

The current optical test instruments basically use professional instruments, which require high precision, support multiple wavelengths, and are equipped with display screens and many operation keys, etc., but this also leads to complex structures, large volumes, cumbersome operations, and high costs. , the price can be as high as several thousand yuan each, and it cannot be popularized to the maintenance personnel to have one, and it is also very inconvenient to use, especially when operating outdoors
