INSTALLATION AND OPERATION INSTRUCTIONS

INTRODUCTION

Thank you for purchasing your American Fibertek RTM-33, which consists of three
multimode video transmitters. Please take a few minutes to read these installation
instructions in order to obtain the maximum performance from this product.

FUNCTIONAL DESCRIPTION

The RTM-33 operates as half of a transmitter / receiver pair for the transmission of three
baseband NTSC, PAL, RS170, or RS343 video signals over three strands of multimode
fiber optic cable. Each of its three independent optical outputs is designed to operate
with the MRM-300, RRM-300, or RRM-33 video receiver. 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 RTM-33 converts three video inputs into three separate FM modulated optical
outputs using a 1300 nm wavelength source for each signal. The M33 Series product is
designed to operate over an optical loss budget range of 0 to 12 dB. The RTM-33
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 LED indicators provide for easy installation and monitoring of video
and power.

The RTM-33 is designed for rack mounting only. For a single channel modular stand
alone version please see the MTM-100.
