INSTALLATION AND OPERATION INSTRUCTIONS
INTRODUCTION
Thank you for purchasing your American Fibertek RT-440C 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 RT-440C 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 RT-440C
is designed to operate with the MR-440C or RR-440C four channel video receiver over one
multimode fiber optic cable.
The RT-440C 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 440C Series product is designed to operate over an optical loss budget range of 0 to
12 dB when used on 62.5 um multimode fiber. A maximum distance of 5km can be achieved as
long as the overall fiber bandwidth maintains a minimum of 150 MHz at 1300 nm. As an
example, if the system fiber has a 600 MHz-km modal bandwidth specification, the 440C will
operate over a distance up to 4 km. The RT-440C 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 designed for rack mounting in any of the four American Fibertek subracks available.
The subrack model numbers are SR-20/1, SR-20R/1, SR-20/2, and SR-20D/2. Slide in rack
mounting and LED indicators provide for easy installation and monitoring of video and dc power.
The RT-440C is designed for rack mounting only. For a modular stand alone version please see
the MT-440C.
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.
