INSTALLATION AND OPERATION INSTRUCTIONS
INTRODUCTION
Thank you for purchasing your American Fibertek RTM-100 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-100 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-100, RRM-100, or RRM-30 video
receiver. The RRM-30 contains the electronics and optics of three RRM-100 units
mounted on one printed circuit board to save space and reduce cost.
The RTM-100 converts a single video input into a single FM modulated optical output
using an 850 nm wavelength source. The M100 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-100 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-100 is designed for rack mounting only. For a modular stand alone version
please see the MTM-100.
