Focal Multiplexer Product Line

914 Multiplexer

FIBER OPTIC MULTIPLEXERS

The 914 video / data multiplexer provides digital fiber optic transmission for 1 high quality video channel and 4-6 bidirectional data channels in the industry’s smallest package. The 914 offers extremely small size; rugged design with extended operational temperature range; bidirectional operation over 1 singlemode or multimode fiber; broadcast quality video with 10-bit digitization and greater than 6 MHz bandwidth for high resolution cameras; 4 bidirectional serial data channels (2 x RS-232, 1 x high speed RS-485, 1 x high speed RS-485 / 422); connector types and pin wiring compatible with the Focal 907; on-board LED diagnostics for data, video, and optical link status; and options for bidirectional video, daughter card expansion and CWDM upgrades.

Features
