Description

A kind of error code instrument system

Technical field

The utility model is related to communication technical field, more particularly, to a kind of error code instrument system.

Background technology

In a communications system, it will usually connect Error Detector in the output end of emitter and the output end of receiver, be used for How many error coded after encoding and decoding and transmission compared.In the prior art, due to a variety of application fields and Application scenario, correspond to different communication protocol and information communication rate, therefore optical device and optical module producer are in order to meet not With product line and need the Error Detector from different rates and communication mode, so occur in that number of types of Error Detector, and And its usage scenario is also relatively simple.

Utility model content

Technical problem to be solved in the utility model, which is to provide one kind, can support a variety of traffic rates, support a variety of logical Believe the error code instrument system of agreement, compatible burst type and continuous signal.

The utility model is the technical scheme adopted is that a kind of error code instrument system, including Error Detector and unit under test, institute Error Detector is stated including user-machine interface module, generation signaling module and signaling module, the user-machine interface mould is received Block includes communication protocol dynamic configuration circuit, and the generation signaling module includes the phaselocked loop for dynamic configuration clock frequency Clock, the signal generator module for producing transmission signal, the high-speed link being connected with the output end of signal generator module are sent Processing module and the alternating current-direct current signal coupling module A being connected with the output end that high-speed link sends processing module, the reception Signaling module includes AC-DC coupling module B, high-speed link receiving processing module, the signal for receiving signal being sequentially connected Receiving module and the comparing module for being contrasted transmission signal with reception signal.

The beneficial effects of the utility model are：According to the type and traffic rate of optical module, dynamically matched somebody with somebody by communication protocol Circuits carry out the suitable communication protocol of dynamic configuration, can configure the driving ginseng on different field optical device and optical module link Number, reaches best operating point, by phase-locked loop clock come dynamic configuration working clock frequency, it is possible to achieve different rates Optical device and optical module finally make generation signaling module and the parameter of reception signaling module reach most preferably the demand of different clocks Working condition, restarts unit under test and enters test mode, the transmission signal of generation is input to by alternating current-direct current signal coupling module A In unit under test, unit under test exports a signal, and output signal is sent into AC-DC coupling module B, and it can support many Traffic rate and communication protocol are planted, can be used for different application fields and application scenario, it is simple and convenient.

As preferential, the high-speed link receiving processing module includes over-sampling process circuit, and the mistake uses circuit The OLT ends optical module being used to detect in passive optical-fiber network.

As preferential, the over-sampling process circuit can carry out sampling processing using five sampling technologies, using five Sampling technology can solve the problem of burst communication clock and data are quickly recovered in passive optical-fiber network, and crosspoint is lost Inclined problem, the over-sampling process circuit can compatible continuous signal and burst, and 10GPON can be supported, so mistake Code instrument system can support two kinds of working methods of burst type error code and continous way error code.
