Abstract
An optical by-pass relay for use with an optical transmission line wherein transmitted optical energy is focused on a light detector for conversion into an electrical signal which electrical signal is coupled to a utilization device. A light emitter coupled to the utilization device, transmits lights onto the transmission line to thereby place the utilization device into the optical transmission line. Means are provided for displacing the detector and emitter from the optical path of the transmission line and for positioning an optical coupler such as a glass rod into the optical path to thereby by-pass the utilization device while providing continuity to the optical signal traversing the optical transmission line.
