Paper Abstract

Fundamental limits in a fiber optic network can dictate the number of video and data channels that can be multiplexed into a cable television network. The most prominent distortions are relative intensity noise (RIN) in the laser diode, nonlinear distortions (NLD) such as those characteristic of the laser diode, and photodiode detector shot noise. According to several researchers, there is a basic limit to the number of cable video channels and the depth of modulation that can be put on a laser diode before impairments distort the video to such an extent as to be unacceptable. This distortion is seen in the form of composite second order (CSO) and composite triple beat (CTB) impairments, as well as clipping noise. This paper shows the development of a laser diode clipping model used to determine and simulate the clipping effect in a laser diode. This model allows a clearer understanding of the affects of clipping in analog and digital carrier networks.
