INSTALLATION AND OPERATION INSTRUCTIONS

INTRODUCTION

Thank you for purchasing your American Fibertek MR-440C multimode four channel 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 MR-440C operates as half of a transmitter / receiver pair for the transmission of four simultaneous, real time, baseband NTSC, PAL, RS170, or RS343 video signals. The MR-440C is designed to operate with the MT-440C or RT-440C video transmitter over one multimode fiber optic cable.

The MR-440C receiver converts a single optical input into a maximum of four video outputs. The 440C Series product is designed to operate over an optical loss budget range of 0 to 12 dB when used on 62.5 um multimode fiber. A maximum distance of 5km can be achieved as long as the overall fiber bandwidth maintains a minimum of 150 MHz at 1300 nm. As an example, if the system fiber has a 600 MHz-km modal bandwidth specification, the 440C will operate over a distance up to 4 km. The MR-440C will also operate on 50 um multimode fiber at a reduced loss budget range. Refer to the product specification sheet for additional performance data.

This unit is contained in a compact and rugged extruded aluminum housing with internal dc voltage regulation. The detachable terminal block and LED indicators provide for easy installation and monitoring of video and power.

The MR-440C is designed for mounting as a modular stand alone unit. For a rack mounted version please see the RR-440C.
