INSTALLATION AND OPERATION INSTRUCTIONS
INTRODUCTION
Thank you for purchasing your American Fibertek RT-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 RT-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 RT-404C
is designed to operate with the MR-404C or RR-404C four channel video receiver over one
multimode fiber optic cable.
The RT-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 RT-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 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-404C is designed for rack mounting only. For a modular stand alone version please see
the MT-404C.
