INSTALLATION AND OPERATION INSTRUCTIONS
Thank you for purchasing your American Fibertek MR-440 multimode four channel video receiver. Please take a few minutes to read these installation instructions in order to obtain the maximum performance from this product.
FUNCTIONAL DESCRIPTION
The MR-440 operates as half of a transmitter / receiver pair for the transmission of four simultaneous, real time, baseband NTSC, PAL, RS170, or RS343 video signals over a single multimode fiber optic cable. It is designed to operate with the MT-440 or RT-440 four channel video transmitter.
The MR-440 receiver converts a single optical input into a maximum of four video outputs. The 440 Series product is designed to operate over an optical loss budget range of 0 to 12 dB. The system’s fiber bandwidth should be a minimum of 150 MHz at 1300 nm. For example, if the system fiber has a 600 MHz-km modal bandwidth specification, the 440 will operate over a distance up to 4 km. The MR-440 operates on 50 um or 62.5 um multimode fiber. Refer to the data sheets for detailed performance specifications.
This unit is contained in a compact and rugged extruded aluminum housing with internal dc voltage regulation. The detachable terminal block and LED indicators provide for easy installation and monitoring of video and power.
The MR-440 is designed for mounting as a modular stand alone unit. For a rack mounted version please see the RR-440.
