Optical module high and low temperature test system

Abstract

The invention belongs to the field of optical communication, and in particular relates to an optical module testing system. A high and low temperature test system for optical modules is proposed, including a test bench, a test door, and a cabinet. The test bench and the test door are fixedly assembled and placed in the cabinet. The test door and the cabinet are sealed and assembled. In the module testing unit, an operation port is opened on the test door at a position facing the optical module testing unit, and a temperature control system and a refrigeration system are arranged in the box. The present invention has simple design, low cost, and is compatible with high and low temperature tests of XFP and SFP / SFP+. A pre-cooling tank is installed adjacent to the XFP and SFP test tanks to pre-cool in advance, greatly saving test waiting time and improving test efficiency. It solves the bottleneck of low temperature testing of optical modules and fills a gap in the current high and low temperature testing system of optical modules.

Description

technical field [0001] The invention belongs to the field of optical communication, and in particular relates to an optical module testing system. [0002] technical background [0003] Optical transceiver integrated module (XFP, SFP, SFP+, SFF, etc.) is an indispensable core component in the optical fiber access network. The optical transceiver integrated module (hereinafter referred to as the optical module) is an optoelectronic system that realizes photoelectric and electro-optical conversion and has an independent transmitting drive and receiving amplifier circuit. Plug and unplug the product. Optical modules play the role of optical repeaters in optical fiber long-distance communication. Optical module testing is the premise to ensure product performance and quality, whether complete and accurate testing can directly determine product quality and cost. There are many testing procedures for optical modules, including initial test at room temperature, final test, high t...

AI Technical Summary

Problems solved by technology

At present, the high-temperature test of optical modules is usually carried out on a heating table, and the low-temperature test is completed in a low-temperature box. The commonly used low-temperature test system is modified by the module manufacturer. Inconvenient, only one product can be tested at a time, and due to the long cooling time, the waiting time of the module from normal temperature to low temperature test is also relatively long, it takes about 15 minutes of pre-cooling to complete the 5-minute test, and the test efficiency is low

At present, there is no high and low temperature testing system dedicated to optical modules. Therefore, the high and low temperature testing of optical modules has always been the bottleneck of optical module production, and the cooling equipment on the market is expensive, resulting in high testing costs for optical modules.
