A cable television system (700) includes a clock source (710) for generating a clock signal, an optical receiver (605) coupled to the clock source (710) for recovering the information in accordance with the clock signal, and an optical transmitter (800) that has input ports (720) for receiving first and second information signals and a clock port (760) for receiving the clock signal. An interleaver (745) within the transmitter (800) is coupled to the input ports (720) and to the clock port (760). The interleaver (745) interleaves bits of the information signals in accordance with the clock signal to generate a serial bit stream that is used to modulate a laser diode (750), thereby generating a digital optical signal that is transmitted to the optical receiver (605) over an optical communication medium (110).
