INSTALLATION AND OPERATION INSTRUCTIONS

INTRODUCTION

Thank you for purchasing your American Fibertek Series 860 multimode six channel

video multiplexer. Please take a few minutes to read these installation instructions in

order to obtain the maximum performance from this product.

FUNCTIONAL DESCRIPTION

The 860 Series units operate as a transmitter / receiver pair for the transmission of six

simultaneous, real time baseband NTSC/PAL video signals over a single multimode

fiber optic cable.

The MRT-860 transmitter accepts six video inputs and multiplexes these signals onto a

single optical output port for connection to the fiber transmission system.

Correspondingly, the MRR-860 receiver converts the optical signal to six independent

video output signals.

The 860 Series units operate on 50 um or 62.5 um multimode fiber. Refer to the data

sheets for detailed performance specifications.

The individual units may be configured for rack mounting or wall mounting depending

upon the position of the included mounting hardware.

INSTALLATION

THE INSTALLATION OF THESE UNITS SHOULD BE MADE BY A QUALIFIED

SERVICE PERSON(S) AND MUST CONFORM TO ALL LOCAL CODES.

To install the MRT-860 or MRR-860 it is first necessary to mount the rack flanges to the

unit.

For rack mounting the ears are installed on the

sides of the unit with the surfaces that have

oval holes flush with the front of the unit as in

Figure 1. Mount the ears with the #10 flathead

screws provided. To mount in the rack cabinet,

use mounting screws that are appropriate for

the rack cabinet being used.

For mounting the unit flush to a wall or other

rigid surface, the ears may be installed on the

sides with the oval holes flush with the bottom of

the unit as in Figure 2. Mount the ears with the

#10 flathead screws provided. Mount the unit to

a rigid surface using #10 (5mm) screws.

POWER SOURCE

The internal power supply accepts universal line voltage. Any mains supply from 100 to

240 VAC, 50 to 60 Hz, may be used without modification or adjustment. A universal

power connector is provided on the rear of the unit to facilitate connection to the power

mains.

POWER CONNECTION

The unit is supplied (in the US and UK only) with a three conductor power cord. The

“ground” conductor is directly connected to the chassis.

INPUT / OUTPUT CONNECTIONS

The fiber optic connection is made via a ST connector located at the back of the unit. Be

sure to allow sufficient room for the required minimum bend radius of the fiber cable

used.

Video input and output connections are located on the rear of the unit. A BNC connector

is provided for each channel. The video inputs are connected to an appropriate 75Ω

baseband video source such as a camera or a video recorder output. The 75Ωvideo

outputs can be looped through typical baseband video inputs of switchers, recorders

and other equipment as required. For proper operation, the outputs must be terminated

with 75Ω. For optimum performance the video cables should be the shortest length of

coax practical.

MRT-860 STATUS INDICATORS

The MRT-860 transmitter provides the following front panel LED status indicators to aid

in installation and troubleshooting:
