Testing of fiber optic cables buried in the ground

Testing shall be done on fibers in one direction at 1550nm, using a pulse width of 30ns since 1550nm is the wavelength that shows stress losses in the fiber best. OTDR traces must be stored and an electronic copy submitted to the project manager. Underground cables are pulled in conduit that is buried underground, usually 1-1. 2 meters (3-4 feet) deep to...
