Optical line terminal equipment test box

Abstract

The invention relates to an optical line terminal equipment test box including a high-low temperature box (1) used for placing a switch to be tested. The high-low temperature box (1) is provided witha heat dissipation port (11). The test box also includes an air pressure pump (2), an air outlet pipeline of the air pressure pump (2) is detachably connected with the heat dissipation port (11), andwhen the air outlet pipeline is connected with the heat dissipation port (11), the high-low temperature box (1) is in a sealed state. Compared with the prior art, the test box disclosed by the invention has high-low temperature simulation and high-low pressure simulation functions, and meets the requirement of the current optical line terminal performance test; a barometer is arranged in the high-low temperature box, the high-low temperature box is made of transparent organic materials, the air pressure state in the box and the physical state of the terminal equipment can be observed at any time, parameter adjusting time is saved, and testing times are reduced.

Description

technical field [0001] The invention relates to a test box, in particular to a test box for optical line terminal equipment. Background technique [0002] The optical line terminal (Optical Line Terminal, OLT) device is an important central office device. Its functions are: 1. Connect with the front-end (convergence layer) switch with a network cable, convert it into an optical signal, and use a single fiber to split the light with the user end. device interconnection. 2. Realize functions such as control, management, and distance measurement of the ONU at the user end. 3. OLT equipment, like ONU equipment, is also an optoelectronic integrated equipment. [0003] Before the optical line terminal goes offline, it needs to perform performance tests on its environmental pressure change tolerance, high and low temperature tolerance, etc. The Chinese patent with the publication number CN106789423A discloses an automatic testing device and testing method, which can generate high...

[0003] Before the optical line terminal goes offline, it needs to perform performance tests on its environmental pressure change tolerance, high and low temperature tolerance, etc. The Chinese patent with the publication number CN106789423A discloses an automatic testing device and testing method, which can generate high and low temperature damp heat environment, but there are limited ways in which the simulated environment can change

There is currently no comprehensive test box that simulates a multi-parameter test environment
