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.

INSTALLATION

THIS INSTALLATION SHOULD BE MADE BY A QUALIFIED SERVICE PERSON AND
SHOULD CONFORM TO THE NATIONAL ELECTRICAL CODE, ANSI/NFPA 70 AND LOCAL
CODES.

Mount the unit to a secure surface using #8 (3mm) hardware in four places. See the drawing on
the next page for mounting dimensions. Be sure to allow sufficient room for the required
minimum bend radius of the fiber cable used.
