INSTALLATION AND OPERATION INSTRUCTIONS

INTRODUCTION

Thank you for purchasing your American Fibertek RT-220C multimode 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 RT-220C 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 RT-220C is designed to operate with the MR-220C or RR-220C two channel video receiver over one multimode fiber optic cable.

The RT-220C 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 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 220C will operate over a distance up to 4 km. The RT-220C 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-220C is designed for rack mounting only. For a modular stand alone version please see the MT-220C.
