INSTALLATION AND OPERATION INSTRUCTIONS
INTRODUCTION
Thank you for purchasing your American Fibertek MT-220C-SL singlemode two 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-220C-SL operates as half of a transmitter / receiver pair for the transmission of two
simultaneous, real time, baseband NTSC, PAL, RS170, or RS343 video signals. The MT-220C-
SL is designed to operate with the MR-220C-SL or RR-220C-SL two channel video receiver
over one singlemode fiber optic cable.
The MT-220C-SL transmitter accepts up to two video inputs. Each video input modulates a
separate FM carrier frequency to allow the total of two video signals to be combined onto one
fiber. The 220C-SL Series product is designed to operate over an optical loss budget range of 0
to 12 dB. The MT-220C-SL operates on 9 um singlemode fiber. Refer to the data sheets for
detailed specifications.
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-220C-SL is designed for mounting as a modular stand alone unit. For a rack mounted
version please see the RT-220C-SL.
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 two places. See the drawing on
