Description
Technical field
The present invention relates to optical communication field, particularly relate to a kind of test macro and method of testing of simplex optical module.
Background technology
Because simplex optical module is the optical module that employing optical fiber carries out receiving and dispatching, so in optical module production process, need to change optical fiber when testing and launching index and reception index, so just bring inconvenience to production, but also likely pollute fiber end face, affect test result, meanwhile, changing optical fiber process also can affect testing efficiency.If can ensure that simplex optical module does not change optical fiber in test process, so not only can reduce end face wiping number of times, avoid end-face pollution, also can enhance productivity widely.
Summary of the invention
For solving the problem, the invention provides a kind of simplex optical module test macro based on optical fiber circulator and method of testing, namely adopting optical fiber circulator to realize simplex optical module production test.
Technical scheme of the present invention is achieved in that
A test macro for simplex optical module, is characterized in that: comprise Error Detector, light source, module to be measured, computer, attenuator, optical fiber circulator, optical branching device, oscilloscope and light power meter;
Wherein, Error Detector, module to be measured, optical fiber circulator are connected successively with oscilloscope, and module to be measured is connected to computer by bus, realize the test macro of module emission parameter;
Error Detector, light source, attenuator, optical branching device, optical fiber circulator, module to be measured connect successively, and optical branching device connects light power meter, and module to be measured is connected to computer by bus, realizes the test macro of module receiving parameter.
Further, described optical fiber circulator has a, b, c tri-ports, optical branching device connectivity port a, module connection ports b to be measured, oscilloscope connectivity port c.
Further, described optical branching device is 1 point of 2 optical branching device.
A method of testing for simplex optical module, is characterized in that comprising:
Test the step of module emission parameter to be measured: Error Detector sends the signal of telecommunication to module to be measured, the light sent from module to be measured inputs from the b port of circulator, light almost milli exports to oscilloscope (other ports almost do not have light output) by c port without loss, reads the parameter of transmitting from oscilloscope;
Test the step of module receiving parameter to be measured: Error Detector sends the signal of telecommunication to light source, light source luminescent is through attenuator attenuates, and by optical branching device one tunnel to light power meter reading, another road light is inputted by optical circulator a port, light almost milli exports to module to be measured (other ports almost do not have light output) by b port without loss, module to be measured converts light to the signal of telecommunication and returns to Error Detector, is used for like this testing receiving parameter;
