INSTALLATION AND OPERATION INSTRUCTIONS
INTRODUCTION
Thank you for purchasing your American Fibertek Series 820C-SL singlemode two 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 820C-SL Series units operate as a transmitter / receiver pair for the transmission of two
simultaneous, real time baseband NTSC/PAL video signals over one singlemode fiber optic cable.
The MRT-820C-SL transmitter accepts up to two video inputs and multiplexes these signals onto a
single optical output port for connection to the fiber transmission system. Correspondingly, the MRR-
820C-SL receiver converts the optical signal to two independent video output signals.
The 820C-SL 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
THIS INSTALLATION SHOULD BE MADE BY A QUALIFIED SERVICE PERSON AND SHOULD
CONFORM TO THE NATIONAL ELECTRICAL CODE, ANSI/NFPA AND LOCAL CODES.
To install the MRT-820C-SL or MRR-820C-SL 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.
