The RRM-1485 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 MTM-1485 or RTM-1485 video transmitter with RS485 transceiver over a single multimode fiber optic cable.
The RRM-1485 converts a FM modulated optical fiber input into a single video output and a single RS485 output using a 1300 nm wavelength detector. The RRM-1485 also converts an electrical RS485 input signal into an optical RS485 output returning on the same fiber using an 850 nm wavelength source. This unit may be configured for two wire half duplex or four wire full duplex electrical interfaces. The M1485 Series product is designed to operate over an optical loss budget range of 0 to 12 dB. The RRM-1485 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 and power. The RRM-1485 is designed for rack mounting only. For a modular stand alone version, please see the MRM-1485.
