INSTALLATION AND OPERATION INSTRUCTIONS

INTRODUCTION

Thank you for purchasing your American Fibertek MRM-300 multimode mini 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 MRM-300 operates as half of a transmitter / receiver pair for the transmission of
baseband NTSC, PAL, RS170, or RS343 video signals over a single multimode fiber
optic cable. It is designed to operate with the MTM-300, RTM-300, or RTM-33 video
transmitter. The RTM-33 contains the electronics and optics of three RTM-300 units
mounted on one printed circuit board to save space and reduce cost.

The MRM-300 converts a single FM modulated optical input into a single video output
using a 1300 nm wavelength detector. The M300 Series product is designed to operate
over an optical loss budget range of 0 to 12 dB. The MRM-300 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 aluminum housing with internal dc
voltage regulation. The detachable terminal block and LED indicators provide for easy
installation and monitoring of video and dc power.

The MRM-300 is designed for mounting as a modular stand alone unit. For a rack
mounted version please see the RRM-300 or the RRM-33.
