TIA EIA/TIA-455-22B

This procedure describes a method to establish the susceptibility of components such as cabled fibers, interconnecting devices, splices, or couplers to ambient light. The test conditions simulate expected conditions to which the fiber optic cable or device may be subjected during actual use.

This test is extremely unlikely to produce failing results for any fiber optic cable that utilizes a black or other opaque-colored jacket, but cable failures may occur when transparent or translucent jackets are employed.
