The ComNet FVT/FVR10D1A21 video transmitter/data transceiver and video receiver/data transceiver series utilizes digital encoding and decoding for high-quality video transmission that meets the requirements of EIA RS-250C for short-haul video transmission. These environmentally hardened units provide transmission of one independent video channel and one bi-directional data channel over one optical fiber and are ideal for use in unconditioned roadside or out-of-plant installations. They also provide transmission of one or two simplex high quality audio signals over the same fiber. The modules use 24-bit 96kHz sample rate digital encoding for superior audio transmission.
