INSTALLATION AND OPERATION INSTRUCTIONS
INTRODUCTION
Thank you for purchasing your American Fibertek Series 91600C multimode sixteen 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 91600C Series units operate as a transmitter / receiver pair for the digital transmission of
sixteen simultaneous NTSC or PAL video signals over one multimode fiber optic cable.
The MRT- 91 6 00C transmitter accepts up to sixteen video inputs in two groups containing eight
videos and multiplexes each group into a high speed serial data stream. The first group s serial
data stream, modulates a laser at 1310nm wavelength. The second group s serial data stream
modulates a laser at 1550nm. A Wave Division Multiplexer (WDM) combines these two
wavelengths, onto a single optical output port for connection to the fiber transmission system.
Correspondingly, the MRR- 91600C receiver converts the optical signal to sixteen i ndependent
video output signals . The 916 00C Series product is designed to operate over an optical loss
budget range of 0 dB to 10 dB on 62.5 um multimode fiber over a maximum distance of 1 Km .
Refer to the product specification sheet for additional performance data.
The individual units may be configured for rack mounting or wall mounting depending upon the
installation of the included mounting hardware. Nominal dimensions of the MRT-91600C and
MRR - 9100C are 1 ¾ inches high by 17 inches wide by 11 ½ inches deep. When mounting
hardware is included, overall width increases to 19 inches wide.
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.
To install the MRT - 91600C or MR R- 91600C it is fir st 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. When mounting
the MRT-91600C or MRR- 91600C in a rack
configuration, it is recommended that sufficient
airflow is available through the unit. This can
be achieved by leaving a 1RU slot above the unit open for air movement and by leaving open
space along the sides of the unit.

For mounting the unit flush to a wall or other rigid
surface, the ears may be installed on the sides
with the oval holes f lush 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
A three conductor power line cord is supplied in the US , UK , and Europe. The ground
conductor is directly connected to the chassis.
FIBER CONNECTION
The fiber optic connection is made via a S T connector located at the back of the unit. Be sure to
allow sufficient room for the required minimum bend ra dius of the fiber cable used.
VIDEO INPUT / OUTPUT CONNECTIONS
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 75 baseband
video source such as a camera or a video recorder output. The 75 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 75 . For optimum
performance the video cables should be the shortest length of coax practical.
