METHOD AND SYSTEM FOR MEASURING AN OPTICAL POWER ATTENUATION VALUE OF A MULTIMODE DEVICE UNDER TEST, RECEIVE DEVICE AND COMPUTER-READABLE MEMORY |
摘要 |
There is provided a method for measuring an optical power attenuation value of a multimode DUT. The method generally has, using an optical source, propagating test light along a multimode device link having a first multimode device, the multimode DUT and a second multimode device serially connected to one another; said propagating including inducing a preferential attenuation of high-order optical fiber modes of the test light along the first multimode device and along the second multimode device; using an optical power detector, detecting an optical signal resulting from the propagation of the test light along the multimode device link and transmitting an output signal based on the detected optical signal; and using a processor, determining the optical power attenuation value of the multimode DUT based on the output signal. |
