Abstract

The invention discloses a 10 Gbps bit error analyzing instrument and aims to provide a bit error analyzing instrument which has low cost, simple and convenient operation and convenient carrying and issuitable for engineering field test. The 10 Gbps bit error analyzing instrument comprises an evaluation board and a single chip microcomputer of C8051 series, wherein the evaluation board can carry out communication with a PC, and a bit error test chip which is connected with equipment to be tested is arranged on the evaluation board; and the single chip microcomputer is used for carrying out communication with an upper PC and a lower test chip, and is provided with a USB interface which carries out communication with the PC and an I2C double line type serial bus which is connected with the bit error test chip to carry out communication and control. The bit error test chip provides sent bit flow and total amount of bit error to the PC through the single chip microcomputer, and the sent bit flow is obtained by test time recorded by the single chip microcomputer and appointed frequency output by the test chip. The invention has the advantages of convenience, rapidness and accurate bit error analysis test and is suitable for performance test of a 10 Gbps communication system.

Description

technical field [0001] The present invention relates to an optical communication instrument for installing and maintaining a high-speed 10G optical network. More specifically, the present invention relates to a code error analysis tester mainly for performing code error analysis on communication equipment around 10Gbps. technical background [0002] In the communication system, network maintenance personnel often encounter problems such as unconnected communication lines, unreceived communication data, high bit error rate of communication lines, mismatching communication network regulations, and failure to connect communication network equipment. The bit error analysis tester is an important tool to help maintenance personnel quickly find out the network problem, solve the network problem and measure the line quality. It mainly performs installation test, project acceptance and daily maintenance on data communication equipment and lines, realizes functions such as data commu...
