QSFP (Quad Small Form-factor Pluggable) module detecting system and detecting method

Abstract

The invention discloses a QSFP (Quad Small Form-factor Pluggable) module detecting system and a detecting method, wherein the system comprises a bit error rate tester and two cross matrixes, wherein a transmission end of the bit error rate tester is connected with any one pair of input terminals of the first cross matrix; a receiving end of the bit error rate tester is connected with any one pair of output terminals of the second cross matrix; the output terminal of the first cross matrix and the input terminal of the second cross matrix are respectively connected with the input terminal and the output terminal of the to-be-tested QSFP; and the two cross matrixes are respectively connected with a main control chip. When in testing, under the control of the control chip, the terminals connected with the cross matrixes and the bit error rate tester are sequentially conducted with the terminal of self opposite terminals so as to sequentially test each passage of the to-be-tested QSFP. In the method provided by the invention, advantages of two QSFP testing methods in the prior art is combined, the digital cross matrixes is adopted to replace the expensive four-channel bit error rate tester, manual operation is automatically replaced so as to flexibly switch signal passages by programming and configuring the cross matrixes, the apparatus cost is reduced and the testing efficiency is greatly improved.

Description

technical field [0001] The invention relates to a detection system, in particular to a QSFP (Quad Small Form-factor Pluggable, four-channel parallel module) module detection system. Background technique [0002] High-speed interconnection communication has become a hot spot for development, especially in the application fields of data communication, telecommunication switches, routers, data aggregation, and backplanes. There is an urgent need for high-density, large-bandwidth, easy-to-maintain, and low-cost solutions. need. And QSFP came into being to satisfy this kind of solution. The speed and density of QSFP are superior to the 4-channel CX4 interface. Since it can support data transmission of four channels at a speed of 10Gbps per channel under the same port volume of XFP (10 Gigabit Small Form Factor Pluggable), the density of QSFP can reach XFP 4 times of the product, 3 times of the SFP+ product. The QSFP interface has been adopted by the InfiniBand standard. [00...

Problems solved by technology

[0004] It can be seen that although the first test method is quick and fast, it requires a four-channel BER tester, which is expensive and the cost of equipment allocated to each product is high; the second test method only requires one Commonly equipped with a single-channel bit error meter, although the equipment cost is greatly reduced, the test steps are cumbersome and inefficient, which greatly increases the working hours of the product
