Up-the-Fiber™ 4200 Bilinx™

Digital video transmitter with Bosch Bilinx™ protocol


Miniature digital video transmitters with Bosch Bilinx™ protocol On an extremely small footprint, the Up-the-Fiber™ (UTF) range of digital fiber-optic equipment provides 9-bit digitised video transmission at the highest quality-price ratio. The Up-the-Fiber 4200 Bilinx series supports Bosch's Bilinx™ protocol over extended distances while exceeding that protocol's limits using digital processing and intelligent features.

The Up-the-Fiber 4200 Bilinx series also offers a one-way isolated contact closure channel to transport alarms from the camera to the central site. Up-the-Fiber 4200 Bilinx systems work with one single-mode fiber or with one or two multimode fibers. Up-the-Fiber 4200 Bilinx receivers can handle one or two video, data and CC channels. The transmitters have a wide operating temperature range, making them suitable for use in outdoor camera housings and camera connection boxes. All miniature stand-alone models can be powered by the camera power supply (12 Vdc or 24 Vac).
