Abstract

A system for certifying physical parameters of fiber optic cabling may include a test device coupled to an end of a fiber optic cable. The test device injects light into the fiber optic cable and conducts a certification test of physical parameters of the fiber optic cable. Based on observation of interaction of the injected light with the fiber optic cable, the test device tests one or more physical parameters of the cable and certifies whether the tested parameters satisfy corresponding parameters specified by a predetermined standard. A separate device may communicate a control signal (e.g., wirelessly) to the test device for controlling an operation of the certification test. The separate device is further operable to receive a result of the certification test from the test device. The separate device may further communicate with a remote computing device updates a database element with information regarding the certification test.
