ABSTRACT:
An apparatus and method for simultaneously testing a plurality of optical fibers, preferably using optical time domain reflectometry, wherein the apparatus includes a light source for providing a pulse of light, at least one splitter means positioned for receiving the pulse of light and for splitting the pulse of light into at least two substantially identical pulses of light, and a plurality of coupling means, each connected to one of the optical fibers under test and each positioned for receiving one of substantially identical pulses of light and directing that pulse of light into an optical fiber. In a preferred embodiment, the backscattered signals from the optical fibers are directed back through the coupling means to a plurality of receivers and data averagers.
