INSTALLATION AND OPERATION INSTRUCTIONS
INTRODUCTION
Thank you for purchasing your American Fibertek Series 860SL singlemode 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 860SL Series units operate as a transmitter / receiver pair for the transmission of
six simultaneous, real time baseband NTSC/PAL video signals over one singlemode
fiber optic cable.
The MRT-860SL 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-860SL receiver converts the optical signal to six independent
video output signals.
The 860SL Series units operate on 9 um singlemode 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-860SL or MRR-860SL 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 FC/PC 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 75Ω video
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.
