INSTALLATION AND OPERATION INSTRUCTIONS

INTRODUCTION

Thank you for purchasing your American Fibertek RT-404 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-404 operates as half of a transmitter / receiver pair for the transmission of four simultaneous, real time, baseband NTSC, PAL, RS170, or RS343 video signals over a single multimode fiber optic cable. It is designed to operate with the MR-404 or RR-404 four channel video receiver.

The RT-404 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 404 Series product is designed to operate over an optical loss budget range of 0 to 6 dB with a maximum distance of up to 1.5 km. The RT-404 operates on 50 um or 62.5 um multimode fiber. Refer to the data sheets for detailed performance specifications.

This unit is designed for rack mounting in any of the three American Fibertek subracks available. The subrack model numbers are SR-20/1, SR-20R/1, and SR-20/2. Slide in rack mounting and LED indicators provide for easy installation and monitoring of video and dc power.

The RT-404 is designed for rack mounting only. For a modular stand alone version please see the MT-404.
