American Fibertek RRM14852F8 Dual Fiber Video Rack Card Transmitter, Multimode

The American Fibertek RTM-1485-2F8 operates as half of a transmitter / receiver pair for the transmission of baseband NTSC, PAL, RS170, or RS343 video signals and bi-directional RS485 data. It is designed to operate with the MRM-1485-2F8 or RRM-1485-2F8 video receiver with RS485 transceiver over two multimode fibers.

The RTM-1485-2F8 converts a single video input along with a single RS485 input into a FM modulated optical fiber output using an 850 nm wavelength source. The RTM-1485-2F8 also converts an optical RS485 signal returning on the same fiber into an electronic RS485 output using an 850 nm wavelength detector. This unit may be configured for two wire half duplex or four wire full duplex electrical interfaces. The M1485-2F8 Series product is designed to operate over an optical loss budget range of 0 to 12 dB. The RTM-1485-2F8 operates on 50 um or 62.5 um multimode fiber.

This unit is designed for rack mounting in any of the three American Fibertek subracks available. The subrack model numbers are SR-20/1, SR-20R/1, and SR-20/2. Slide in rack mounting and LED indicators provide for easy installation and monitoring of video, data, and power. The RTM-1485-2F8 is designed for rack mounting only. For a modular stand alone version please see the MTM-1485-2F8.
