The FTV10D1A2/FRV10D1A2 fiber transmitter and receiver provide simultaneous transmission of one bidirectional video channel, one bidirectional data channel, two bidirectional audio channels, and one bidirectional contact closure over one optical fiber in a two-slot wide design. Units are available in single-mode and multimode versions. The FTV10D1A2 transmitter and FRV10D1A2 receiver provide transmission of two bidirectional 24-bit (96 kHz) audio signals with sample rate digital encoding for superior transmission of balanced line-level audio. Data selection offers a choice of RS-232, RS-422, and RS-485 (2-wire/4-wire), Manchester, and Bi-Phase Communication. The FTV10D1A2/FRV10D1A2 plug-and-play design ensures ease of installation by requiring no electrical or optical adjustments. Modular in design, FTV10D1A2 and FRV10D1A2 units can be rack-mounted using the EURACK/USRACK chassis, or stand-alone modules can be placed on a desktop or mounted to a wall (wall mount kit not required). For stand-alone and wall mount installations, external power is required for the FTV10D1A2/FRV10D1A2 units. The units can be powered with the recommended FEXTPS fiber external power supply.
