ABSTRACT:
An optical switch device for switching test signals to the terminated ends of a predetermined number of optical fibers in an optical fiber cable. The optical switch device contains a first optical port for receiving the test signals. A plurality of optical second ports are provided, wherein the number of second optical ports is less than the number of optical fibers in the cable to be tested. The optical connector ports are connected to the terminated ends of optical fibers in the optical cable by a plurality of detachable adapters. Each of the adapters has a base connector that selectively engages one of the second optical ports on the optical switch device. A plurality of optical leads extends from the base connector of the adaptor. The optical leads terminate with a plurality of plugs that are adapted to selectively engage some of the terminated ends of the optical fibers in the optical cable. The plugs at one end of the adapters are first connected to the optical fibers in the optical cable. The base connectors coupled to the plugs are fewer in number than optical fibers by a ratio of at least 1:2. The base connectors are then connected to the optical switch, thereby allowing for a connection operation that is more time efficient and space efficient than was previously available.
