Abstract
An optical waveguide optical amplifier device for use with an optical telecommunications system that transmits optically amplifiable subscriber channels and communicates service information internally within the system with optical service channels and includes an optical amplifier input, an amplifier output, and optical amplifier medium. The optical amplifier input includes a reflective isolator longitudinal body with a first end and a second end. The first end includes an input fiber for receiving the subscriber and optical service channels inputted into the amplifier input and an output fiber for transmitting the subscriber channels to the amplifier medium. The second end of the reflective isolator body includes an optical service channel accessor which guides the subscriber channels to the output optical fiber. The amplifier device further includes an optical service channel receiver connected to the optical service channel accessor such that an optical service channel that enters the reflective isolator body from the input fiber is transmitted through the optical service channel accessor to the receiver and away from the output fiber.
