INSTALLATION AND OPERATION INSTRUCTIONS

INTRODUCTION

Thank you for purchasing your American Fibertek RTM-300 multimode video
transmitter. Please take a few minutes to read these installation instructions in order to
obtain the maximum performance from this product.

FUNCTIONAL DESCRIPTION

The RTM-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 MRM-300, RRM-300, or RRM-33 video
receiver. The RRM-33 contains the electronics and optics of three RRM-300 units
mounted on one printed circuit board to save space and reduce cost.

The RTM-300 converts a single video input into a single FM modulated optical output
using a 1300 nm wavelength source. The M300 Series product is designed to operate
over an optical loss budget range of 0 to 12 dB. The RTM-300 operates on 50 um or

62.5 um multimode fiber. Refer to the data sheets for detailed performance
specifications.

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 a LED indicator provide for easy installation and monitoring of video
and power.

The RTM-300 is designed for rack mounting only. For a modular stand alone version
please see the MTM-300.
