American Fibertek RT440C Single Fiber, Four Channel FM Video Rack Card Transmitter, 5km

The American Fibertek RT440C operates as half of a transmitter / receiver pair for the transmission of four simultaneous, real time, baseband NTSC, PAL, RS170, or RS343 video signals. The RT440C is designed to operate with the MR-440C or RR-440C four channel video receiver over one multimode fiber optic cable.

The RT440C transmitter accepts up to four video inputs. Each video input modulates a separate FM carrier frequency to allow the total of four video signals to be combined onto one fiber. The 440C Series product is designed to operate over an optical loss budget range of 0 to 12 dB when used on 62.5 um multimode fiber. A maximum distance of 5km can be achieved as long as the overall fiber bandwidth maintains a minimum of 150 MHz at 1300 nm. As an example, if the system fiber has a 600 MHz-km modal bandwidth specification, the 440C will operate over a distance up to 4 km. The RT440C will also operate on 50 um multimode fiber at a reduced loss budget range.

This unit is designed for rack mounting in any of the four American Fibertek subracks available. The subrack model numbers are SR-20/1, SR-20R/1, SR-20/2, and SR-20D/2. Slide in rack mounting and LED indicators provide for easy installation and monitoring of video and DC power. The RT440C is designed for rack mounting only. For a modular stand alone version please see the MT-440C.
