Description
Technical field
The present invention relates to the test macro that uses in a kind of fiber optic communication field, particularly a kind of optical branching device Performance Test System.
Background technology
In Fibre Optical Communication Technology, what Fiber to the home Access Network adopted is passive optical network structure, and optical branching device is one of crucial optical device in the EPON, sends in order to the broadcast type of realizing downlink optical signal.The optical branching device of 1 * N port; Requirement is assigned to the light signal of input port in each output port uniformly; And keep less Polarization Dependent Loss, therefore must test the technical indicators such as insertion loss, loss uniformity and Polarization Dependent Loss of optical branching device.And optical branching device is generally operational in 1310nm, 1490nm and three optical bands of 1550nm, therefore need test one by one the device performance of these three wave bands.
To the existing testing scheme of optical branching device performance, a kind of is one by one the performance index of each passage under each wavelength to be tested, and with the various performance index of calculating software analyzer spare, this scheme testing efficiency is too low again.Second kind of scheme is; With a N * 1 optical switch; Each output of optical branching device is switched to light power meter successively test, still there is inefficient shortcoming in this scheme, needs for 10 seconds such as the Polarization Dependent Loss of a port of test; The Polarization Dependent Loss of the optical device of then testing one 1 * 32 port under a wavelength needed for 320 seconds, and precision of test result influenced by the repeatability of optical switch bigger.The production field of optical branching device is badly in need of a kind of high efficiency test macro, the indexs such as insertion loss, loss uniformity and Polarization Dependent Loss of device is tested simultaneously, to improve testing efficiency.
Summary of the invention
The object of the present invention is to provide a kind of optical branching device Performance Test System, satisfy the test request that optical branching device is inserted technical indicators such as loss, loss uniformity and Polarization Dependent Loss, improve testing efficiency.
Technical scheme of the present invention is: a kind of optical branching device Performance Test System; It is characterized in that: it is made up of a multi wave length illuminating source, Polarization Controller, band fiber branching device, multichannel light power meter, computer and a cover supervision test software; The computer control signal line connects multi wave length illuminating source, and the light source of multi wave length illuminating source output is drawn a light source output port through optical fiber and Polarization Controller; The fine end of the band of band fiber branching device is the light source input port, and every optical fiber of the naked fine end of band fiber branching device all is connected respectively on each passage of multichannel light power meter; The multichannel light power meter connects the signal input port of computer through data wire.
Equip the semiconductor laser of 1310nm, 1490nm and three wavelength of 1550nm in the described multi wave length illuminating source, it can detect the performance of optical branching device under 1310nm, 1490nm and three optical band operating states of 1550nm one by one.
Described multichannel light power is in respect of 32 road optical fiber input channels, and it can detect the optical branching device of 32 cores at most.
Advantage of the present invention is: the present invention includes a computer and a cover supervision test software; It can be controlled light source and produce the light source that end sends 1310nm, 1490nm and three wavelength of 1550nm; And change linearly polarized light into through Polarization Controller; Load light source through the light source output port to optical branching device; Optical branching device all is connected respectively on each passage of multichannel light power meter through the every optical fiber that makes of band fiber branching device, and the multichannel light power meter can be gathered the optical power value of all passages in real time, is transferred in the controlling computer through serial ports.Through computer and supervision test software, the minimum and maximum insertion loss value of recording light splitter automatically obtains the Polarization Dependent Loss of to be measured each passage automatically; The indexs such as insertion loss, loss uniformity and Polarization Dependent Loss of optical branching device under different wave length tested simultaneously, and test result is saved as the file format that needs, and testing efficiency is high.It can also be used for the production process of optical branching device, shows in real time through the block diagram in the software not transfer to the insertion loss objective of each passage qualified passage and indicate with redness, transfers to qualifiedly then to indicate with blueness, can enhance productivity.
