A method and apparatus for changing the path of an optical signal are disclosed. An optical bypass device having an optical input and output, and a waveguiding region optically connecting the input and output, is used to form a multiplicity of improved connectors and switches. In a first embodiment of the device, the waveguiding region comprises a plurality of reflective surfaces. In a second embodiment, the waveguiding region comprises a core of optically suitable material and a layer of cladding, where the relationship between the refractive index of the core and cladding is such that an optical signal may be guided by the core. The optical bypass device is integrated, with and without actuating means, into various connectors to provide loopback of an optical signal when a connector is de-mated. |
