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.
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
