From American Fibertek, utilizing state- of-the-art serial data multiplexing and hi-resolution 10-bit analog to digital conversion architecture, the 900 series of video multiplexers eclipses the performance of 8-bit systems with significantly higher video grey scale resolution and signal to noise ratio with no trade off in loss budget. Advanced electronics and wavelength division multiplexing using superior optical components allows four videos and two-way data to be multiplexed with complete transparent performance. Also, the Digital 940 Series, a digital video multichannel transmission system, includes two different models to provide selection of transmission capabilities on both multimode and singlemode fiber.
