INTRODUCTION

Thank you for purchasing your American Fibertek MT-740C-SL singlemode 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-740C-SL operates as half of a transmitter / receiver pair for the transmission of four
channels of high performance digital NTSC, PAL, RS170, or RS343 video signals. The MT­740C-SL is designed to operate with the MR-740C-SL or RR-740C-SL video receiver over one
singlemode fiber optic cable.

The MT-740C-SL multiplexes four video input signals into a high speed serial data stream. This
serial data stream modulates a laser at 1310 nm wavelength. The 740C-SL Series product is
designed to operate over an optical loss budget range of 0 to 21 dB. Refer to the data sheets
for detailed performance specifications.

This unit is contained in a rugged aluminum housing with internal dc voltage regulation. The
detachable terminal blocks and LED indicators provide for easy installation and monitoring of
video and power.

The MT-740C-SL is designed for mounting as a modular stand alone unit. For a rack mounted
version please see the RT-740C-SL.
