INSTALLATION AND OPERATION INSTRUCTIONS

INTRODUCTION

Thank you for purchasing your American Fibertek RTM-30, 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-30 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-100, RRM-100, or RRM-30 video receiver. The RTM-30 contains the electronics and optics of three RTM-100 units mounted on one printed circuit board to save space and reduce cost.

The RTM-30 converts three video inputs into three separate FM modulated optical outputs using an 850 nm wavelength source for each signal. The M30 Series product is designed to operate over an optical loss budget range of 0 to 12 dB with a maximum distance of up to 2.5 km. The RTM-30 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-30 is designed for rack mounting only. For a single channel modular stand alone version please see the MTM-100.
