Single-ended pre- donsole, and be multi beam cable, during the test if plugging switching frequently in input terminal to test, certainly will will cause
Differential loss influences, and the transmitting terminal light source that the utility model introduces photoswitch design avoids the plug behaviour during one group of data test
Make, so that this group of test data is when accurate to stabilization.
The utility model contemplate site installation particularity, scene it is various it is possible that the problem of, if
Farther out, contrast test obtains original value and actual value to tested optical cable both ends distance back and forth, certainly will increase human operational error, artificially
Careless omission error equiprobability, is unfavorable for test job, may finally influence whether the normal work of site protective device.Therefore needle
To this special case situation, receiving end test host has wireless transmission function, can allow two different hosts difference test optical fibre cables away from
From farther away two, wireless communication measured data information to interact ensure that the accuracy of test.
The utility model is clear in structure, simple and clear, and research and development progress is fast, and hardware cost is low；Laser therein, light are opened
Pass, splitter all have high precision performance, and the utility model has excellent test performance.
In the specific implementation, the photoswitch of transmitting terminal is 1 point of 16 tunnel, and one end is the access of 1 road light source, by point of photoswitch
Road control, another end are optional 16 paths output, adapt to the pre- donsole multicore testing requirement of site optical cable.
Optional 16 paths obtained through photoswitch go out single-ended prefabricated female and 16 tunnels of 16 cores using demultiplexer separates
The port LC to be measured, final output interface of both ports as transmitting terminal light source.Single-ended prefabricated female is in order to test site
Protect the single-ended pre- donsole of optical cable；And the port LC to be measured obtains the currently transmitted original DB value of end light source to test.Receive end main frame
The original DB value currently tested is obtained by the port LC to be measured and is stored.
In the above-mentioned technical solutions, site protection optical cable dispersion is tested to terminate into reception end main frame optical power detecting mouth,
The data that light power meter collects pass to host CPU, converted and final DB value is calculated.It can pass through in transmitting terminal
Switch photoswitch, allows and receive end main frame to test 16 tunnel difference DB values of site protection optical cable dispersion and store.Host
The 16 road original values and test value that may bring up storage are shown on liquid crystal display, the performance of 16 road optical cables respectively by drawing
Situation is very clear.
In the above-mentioned technical solutions, using photoswitch come 16 road DB value of switch test, plug switching times manually are saved.
Both the testing time is saved, the influence of the differential loss as caused by plugging is in turn avoided.
In the above-mentioned technical solutions, if the both ends distance of site protection optical cable farther out, in order to avoid back and forth when test
It runs and obtains original value and test value, two reception end main frames can be used, it is former that a host tests acquisition at transmitting terminal light source
Initial value, another host obtain test value at site protection fiber optic testing end, and final two hosts pass through wireless transmission function,
The DB value for exchanging oneself acquisition each other, can both draw the comparison diagram of original value and test value on the liquid crystal display of oneself, show
