Abstract :
We demonstrate simultaneous transmission of 80 AM-VSB cable television (CATV) video signals at 1.55-μm and 155-Mb/s data signal at 1.3-μm over a multimode fiber (MMF) local area network (LAN). Excellent system performance of carrier-to-noise ratio, composite second order, and composite triple beat for video signals and bit-error-rate for the data signal can be achieved. The required coupler ratios for tapping the video power off at each node and the required output power of CATV transmitter for the MMF-LAN with different network sizes and spans have been investigated. This technique allows video broadcasting together with data service to buildings and classrooms through the existing MMF-LAN.
