INSTALLATION AND OPERATION INSTRUCTIONS
INTRODUCTION
Thank you for purchasing your American Fibertek MR-91P088SL singlemode video receiver with two channels of
bi-directional audio. Please take a few minutes to read these installation instructions in order to obtain the
maximum performance from this product.
FUNCTIONAL DESCRIPTION
The MR-91P088SL 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 MR-91P088SL also supports two bi-directional channels
of four wire audio. The MR-91P088SL is designed to operate with the MT-91P088SL or RT-91P088SL video
transmitter with bi-directional data and audio over one singlemode fiber optic cable.
The MR-91P088SL multiplexes two audio signals into a high speed serial data stream. This serial data stream
modulates a laser at 1550 nm wavelength. The MR-91P088SL also detects and demultiplexes a return optical
serial data stream signal containing a single video input signal along with two audio channels at 1310 nm
wavelength. The 91P088SL Series product is designed to operate over an optical loss budget range of 0 to 21dB.
Refer to the data sheet for detailed performance specifications.
This unit is contained in a rugged aluminum housing with internal dc voltage regulation. The detachable terminal
blocks and LED indicators provide for easy installation and monitoring of video, audio, and optical power. The
MR-91P088SL is designed for mounting as a modular stand alone unit. For a rack mounted version please see
the RR-91P088SL.
