INSTALLATION AND OPERATION INSTRUCTIONS
INTRODUCTION
Thank you for purchasing your American Fibertek RTM-61 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-61 operates as half of a transmitter / receiver pair for the transmission of baseband NTSC,
PAL, RS170, or RS343 video signals and bi-directional Sensornet data. It is designed to operate with
the MRM-61 or RRM-61 video transmitter over a single multimode fiber optic cable.
The RTM-61 converts a single video input and a single Sensornet input into an optical output using a
1300 nm wavelength source. The RTM-61 also converts an optical input signal returning on the same
fiber into a Sensornet output signal using an 850 nm wavelength detector. The M61 Series product is
designed to operate over an optical loss budget range of 0 to 12 dB. The RTM-61 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-61 is designed for rack mounting only. For a modular stand alone version please see the
MTM-61.
