ABSTRACT:
A transmitter optical subassembly includes an optical emitter and a fiber receptacle within which an optical fiber is received. An optical limiting element is positioned between the optical emitter and the fiber receptacle. When an optical signal is emitted from the optical emitter, the optical signal passes through the optical limiting element before the optical signal reaches the fiber receptacle and is received by the optical fiber. The optical limiting element has a property such that if the power of the optical signal entering the optical limiting element exceeds a predetermined limit, the power of the optical signal is optically attenuated so that the power of the optical signal exiting the optical limiting element remains below a predetermined limit.
