Broadband Video Over UTP Baluns

PV 880 Series

Broadband video (CATV) over UTP, once thought to be impractical (or impossible), is now commonplace, due to the use of the PV880 Series of Broadband Video Baluns from ETS. Commercial and professional grade video can be transmitted over Category 5 and better UTP. Distance is a function of frequency and signal level. Using Category 5 or better cable, all channels up to 26, at a drive level of not more than 36dBmV will accommodate 100 meters. The usable distance is reduced at higher channels, reaching 50 meters at channel 78. APPLICATION NOTE – Off air channel 26 is 542 to 548 MHz. CATV allows packing channels into unused on-air frequencies. Applications include Media Retrieval Systems, Schools, Churches, Production Monitoring, Security and Surveillance, Displays, “Smart” Houses, Teleconferencing, Cable TV Distribution. Bandwidth to 550 MHz (CATV channel 70+).

Expanding the territories opened by the Broadband Video Baluns, ETS introduces the PV884 and PV885 – ULTRA Broadband Video Baluns. The frequency range has been increased and EMI reduced, both due to enhanced filtering and an all metal enclosure. FCC requirements preclude boosting signal levels to the values required to guarantee preset distances. Distance achievable is a function of signal level, balance and the degree to which the cable used unbalances the signal. Cat5e maintains signal balance at least 5 dB better than Cat5. Level 7 (or equivalent) cable is another 5 dB better, providing for a signal drive level of not more than 46 dBmV. The PV884 offers a BNC connector for use with professional grade equipment. “Prosumer” and consumer electronics which connect using ‘F’ connectors will require our PV885 balun. Bandwidth to 850 MHz (CATV channel 120+).
