A laser coupled to pass a coherent light beam at a specific wavelength through an optical isolator serves as a modulated light source. The isolator prevents an optical reflection which allows the laser to operate in a stable manner. An external modulator receives the light from the laser and modulates the beam with an RF signal applied to the i/p terminal. The RF signal comprises the multichannel AM-VSB signal. Another isolator at the o/p of this modulator buffers the modulator from the fiber coupler. The o/p from the modulated light source is coupled to one input of a fiber coupler. Another input of fiber coupler is driver by a pump laser which operates in the pump band of the optical fiber which forms an optical amplifier in combination with the pump laser and fiber coupler. The fiber is coupled to the o/p of fiber coupler via a conventional fiber connector. The o/p of the amplifier is coupled to a conventional optical fiber. The signal distributed over the optical fiber is received at the fiber optic receiver and information contained therein is delivered at the o/p terminal.
