MODEL LP1500

Digital Fiber Optic 250C Short Haul Analog Video Transport System with SDV or HDTV Digital Video

DESCRIPTION

Model LP1500 The 1500 Series is a high performance, yet affordable, Fiber Optic 250C Short Haul Analog Video Transport System with SDV/HDTV Digital Video. The standard 1500 system is designed to transport one broadcast quality 250C analog video channel, four professional grade analog audio channels, and/or one RS-232 (or RS-422) channel, as well as one SMPTE-259M (SDV) or SMPTE-292M (HDTV) serial digital video signal, over long distance through either singlemode or multimode fiber. Many versions of optical transmitter and receiver combinations are available to address different distance requirements.

Due to the use of advanced digital fiber optic transmission technology, the quality of analog video, audio and data transmission is superior to the analog counterparts. No user adjustments are required in the 1500 system, enabling quick setup and trouble-free operation.

The 1500 comes with a rugged, standalone, rackmountable unit. Panel connectors are provided for analog baseband video (BNC connector), analog stereo audio (terminal block), RS-232/RS-422 data (DB9 connector), SDV/HDTV digital video (BNC connector), and fiber connection (FC-type for the singlemode version or ST-type for the multimode version). The 1500 can be easily monitored by front panel LED indicators for power, optical link, and channel activity.

The 1500 design is capable of addressing a variety of non-standard configurations. Contact us to discuss your custom, OEM/private brand and high volume requirements.
