INSTALLATION AND OPERATION INSTRUCTIONS

INTRODUCTION

Thank you for purchasing your American Fibertek RT-440C-E multimode four channel video
transmitter. Please take a few minutes to read these installation instructions in order to obtain
the maximum performance from this product.

FUNCTIONAL DESCRIPTION

The RT-440C-E 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 RT-440C­E is designed to operate with the MR-440C-E or RR-440C-E four channel video receiver over
one multimode fiber optic cable.

The RT-440C-E transmitter accepts up to four video inputs. Each video input modulates a
separate FM carrier frequency to allow the total of four video signals to be combined onto one
fiber. The 440C-E Series product is designed to operate over an optical loss budget range of 5
to 16 dB when used on 62.5 um multimode fiber. A maximum distance of 8km can be achieved
as long as the system fiber cable used has a modal bandwidth specification of 600 MHz-km or
higher. Lower bandwidth specifications will result in a reduced maximum distance. The RT­440C-E 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 designed for rack mounting in any of the four American Fibertek subracks available.
The subrack model numbers are SR-20/1, SR-20R/1, SR-20/2, and SR-20D/2. Slide in rack
mounting and LED indicators provide for easy installation and monitoring of video and dc power.

The RT-440C-E is designed for rack mounting only. For a modular stand alone version please
see the MT-440C-E.

THIS INSTALLATION SHOULD BE MADE BY A QUALIFIED SERVICE PERSON AND
