INSTALLATION AND OPERATION INSTRUCTIONS

INTRODUCTION

Thank you for purchasing your American Fibertek MT-404C 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 MT-404C 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 MT-404C is designed to operate with the MR-404C or RR-404C four channel video receiver over one multimode fiber optic cable.

The MT-404C 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 404C Series product is designed to operate over an optical loss budget range of 0 to 6 dB and a maximum distance of 2.5km when used on 62.5 um multimode fiber. The MT-404C 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 supply.

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