INSTALLATION AND OPERATION INSTRUCTIONS
INTRODUCTION
Thank you for purchasing your American Fibertek RRM-30 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-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 inputs is designed to operate with
the MTM-100, RTM-100, or RTM-30 video transmitter. 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 RRM-30 converts three FM modulated optical inputs into three seperate video
outputs using an 850 nm wavelength detector 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 RRM-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 a LED indicator provide for easy installation and monitoring of video
and dc power.
The RRM-30 is designed for rack mounting only. For a single channel modular stand
alone version please see the MRM-100.
