INSTALLATION AND OPERATION INSTRUCTIONS

INTRODUCTION

Thank you for purchasing your American Fibertek MT-91P089 multimode video transmitter 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 MT-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 MT-91P089 also supports one bi-directional channel of four wire audio and one bi-directional channel of contact closure. The MT91P089 is designed to operate with the MR-91P089 or RR-91P089 video receiver over one multimode fiber optic cable.

The MT-91P089 multiplexes a single video input signal along with one audio signal and one contact closure signal into a high speed serial data stream. This serial data stream modulates a laser at 1310 nm wavelength. The MT-91P089 also detects and demultiplexes a return optical serial data stream signal containing one audio signal and one contact closure signal at 1550 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 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, contact closure, and optical power. The MT-91P089 is designed for mounting as a modular stand alone unit. For a rack mounted version please see the RT-91P089.
