INSTALLATION AND OPERATION INSTRUCTIONS
INTRODUCTION
Thank you for purchasing your American Fibertek RRM-1400 multimode video receiver. Please take a few
minutes to read these installation instructions in order to obtain the maximum performance from this
product.
FUNCTIONAL DESCRIPTION
The RRM-1400 operates as half of a transmitter / receiver pair for the transmission of baseband NTSC,
PAL, RS170, or RS343 video signals with bi-directional RS422 data. It is designed to operate with the
MTM-1400 or RTM-1400 video transmitter over a single multimode fiber optic cable.
The RRM-1400 converts an optical fiber input into a single video output and a single RS422 output using a
1300 nm wavelength detector. The RRM-1400 also converts an electrical RS422 input signal into an optical
RS422 output returning on the same fiber using an 850 nm wavelength source. The 1400 Series product is
designed to operate over an optical loss budget range of 0 to 12 dB. The RRM-1400 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 indicator
