INSTALLATION AND OPERATION INSTRUCTIONS

INTRODUCTION

Thank you for purchasing your American Fibertek RR-91P089 multimode video receiver with bi­directional audio and bi-directional contact closure. Please take a few minutes to read these installation
instructions in order to obtain the maximum performance from this product.

FUNCTIONAL DESCRIPTION

The RR-91P089 operates as half of a transmitter / receiver pair for the transmission of high
performance 10 bit digital NTSC, PAL, RS170, or RS343 video signals. The RR-91P089 also supports
one bi-directional channel of four wire audio and one bi-directional channel of contact closure. The RR­91P089 is designed to operate with the MT-91P089 or RT-91P089 video receiver over one multimode
fiber optic cable.

The RR-91P089 multiplexes one audio signal and one contact closure signal into a high speed serial
data stream. This serial data stream modulates a laser at 1550 nm wavelength. The RR-91P089 also
detects and demultiplexes a return optical serial data stream signal containing a single video output
signal along with one audio signal and one contact closure signal at 1310 nm wavelength. The 91P089
Series product is designed to operate over an optical loss budget range of 0 to 12 dB with a maximum
distance of 4Km. Refer to the data sheet for detailed performance specifications.

This unit is designed for rack mounting in either of two American Fibertek subracks available. The
subrack model numbers are SR-20/2 or SR-20D/2. Slide in rack mounting, detachable terminal blocks,
and LED indicators provide for easy installation and monitoring of video, audio, contact closure, and
optical power. The RR-91P089 is designed for rack mounting. For a modular stand alone version
please see the MR-91P089.
