INSTALLATION AND OPERATION INSTRUCTIONS
INTRODUCTION
Thank you for purchasing your American Fibertek MT-984C-SL singlemode eight channel digital video
transmitter with RS485, RS422, RS232 or Manchester data. Please take a few minutes to read these
installation instructions in order to obtain the maximum performance from this product.
FUNCTIONAL DESCRIPTION
The MT-984C-SL operates as half of a transmitter / receiver pair for the transmission of eight channels
of high performance 10 bit digital NTSC, PAL, RS170, or RS343 video signals. The MT-984C-SL also
supports one bi-directional RS485, RS422, RS232 or a return Manchester data channel. The RS485
channel may be configured for 2-wire (half duplex) or 4-wire (full duplex) operation The MT-984C-SL is
designed to operate with MR-984C-SL or RR-984C-SL video receiver with bi-directional data over one
singlemode fiber optic cable. LED indicators provide for easy monitoring of video, data, and optical
power.
The MT-984C-SL multiplexes eight video input signals along with one data signal into a high speed
serial data stream. This serial data stream modulates a laser at 1310 nm wavelength. The MT-984C-SL
also detects and demultiplexes a return optical serial data stream containing one data signal at 1550
nm wavelength. Refer to the data sheets for detailed performance specifications.
