Abstract:
An optical waveguide optical amplifier device for use with an optical telecommunications system that transmits a plurality of optically amplifiable subscriber channels and communicates a plurality of service information desired internally within the optical telecommunications system via an optical service channel, said amplifier device comprising:(i) an optical amplifier input; (ii) an optical amplifier output, and an optical amplifier medium between said amplifier input and said amplifier output, said amplifier medium optically amplifying said optically amplifiable subscriber channels; (iii) an optical amplifier optical service channel receiver which receives said service information desired internally within the optical telecommunications system; (iv) wherein said optical amplifier input comprises: (a) a reflective isolator longitudinal body having a first end and a distal opposing second end, said first end including an input optical fiber, said input optical fiber receiving said optically amplifiable subscriber channels and said optical service channel inputted into said optical amplifier input, said reflective isolator longitudinal body first end further comprising an output optical fiber, said output optical fiber transmitting said optical amplifiable subscriber channels to said optical amplifier medium; and (b) said reflective isolator longitudinal body second end including an optical service channel accessor which transmits said optical service channel to said service channel receiver and guides said optically amplifiable subscriber channels to said output optical fiber.
