INSTALLATION AND OPERATION INSTRUCTIONS
INTRODUCTION
Thank you for purchasing your American Fibertek RRM-33, which consists of three
multimode video receivers. Please take a few minutes to read these installation
instructions in order to obtain the maximum performance from this product.
FUNCTIONAL DESCRIPTION
The RRM-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 inputs is designed to
operate with the MTM-300, RTM-300, or RTM-33 video transmitter. 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 RRM-33 converts three FM modulated optical inputs into three separate video
outputs using a 1300 nm wavelength detector for each signal. The M33 Series product
is designed to operate over an optical loss budget range of 0 to 12 dB. The RRM-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 a LED indicator provide for easy installation and monitoring of video
and power.
The RRM-33 is designed for rack mounting only. For a single channel modular stand
alone version please see the MRM-300.
