INSTALLATION AND OPERATION INSTRUCTIONS
INTRODUCTION
Thank you for purchasing your American Fibertek Series 94800C-SL singlemode forty-eight
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 94800C-SL Series units operate as a transmitter / receiver pair for the digital transmission
of forty-eight simultaneous NTSC or PAL video signals over one singlemode fiber optic cable.
The RT-94800C-SL transmitter accepts up to forty-eight video inputs in six groups containing
eight videos each and multiplexes each. The first group’s serial data stream modulates a laser
at 1470nm wavelength. The second group’s serial data stream modulates a laser at 1490nm
wavelength. This pattern is repeated for group’s three through six using wavelengths 1510nm
through 1570nm respectively. A Course Wave Division Multiplexer (CWDM) combines these six
wavelengths onto single optical output port for connection to the fiber transmission system.
Correspondingly, the RR-94800C-SL receiver converts the optical signal to forty-eight
independent video output.
The 94800C-SL Series product is designed to operate over an optical loss budget range of 0dB
to 21dB on 9um singlemode fiber. Refer to the product specification sheet for additional
performance data.
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.

RT-94800C-SL COMPONENTS
The RT-94800C-SL consists of the following components:
1) RT-980C-1470 1) RT-980C-1530 1) SR-20
1) RT-980C-1490 1) RT-980C-1550 6) PCSC/UPC-0.4 1) PSR-2
1) RT-980C-1510 1) RT-980C-1570 1) MTX-CWDM-8 1) BPS-2
The individual 980C series video rack cards that make up the RT-94800C-SL are combined in a
rack mount configuration using the SR-20 subrack. Please refer to the instruction manuals for
the SR-20 and the PSR-2 for information on the installation of the subrack with its power supply.
The individual 980C series rack cards can slide into any of the open slots in the SR-20 subrack,
however, the recommended configuration is shown below. The lowest wavelength video card,
the RT-980C-1470 is installed on the right side of the subrack next to the power supply. The RT-
980C-1490 is installed next to the RT-980C-1470 and so on as shown below. Following this
configuration allows the fiber ports on the back of the 980C series cards to best line up with its
associated ports on the CWDM unit. Use a small screwdriver to push and lock the ¼ turn
fasteners into place.
The Multi-Channel Digital Video CWDM that optically multiplexes the six video rack cards used
in the RT-94800C-SL is labeled MTX-CWDM-8. It should be mounted directly below its
corresponding SR-20 subrack with a ½ RU space between the two components. To maximize
the performance and life of the system, installing a fan above the SR-20 subrack is
recommended to pull air up across the RT-94800C-SL components.
There is a blank slot on the left side of the subrack. This slot may be used to expand the
configuration to 56 channels by adding an RT-980C-1590 transmitter and corresponding
receiver. The MTX-CWDM-8 can accommodate up to eight 980C transmitters

RR-94800C-SL COMPONENTS
The RR-94800C-SL consists of the following components:
1) RR-980C-1470 1) RR-980C-1530 1) SR-20
1) RR-980C-1490 1) RR-980C-1550 6) PCSC/UPC-0.4 1) PSR-2
1) RR-980C-1510 1) RR-980C-1570 1) MRX-CWDM-8 1) BPS-2
The individual 980C series video rack cards and that make up the RR-94800C-SL are installed
in a manner similar to the RT-94800C-SL (see drawing below). The Multi-Channel Digital Video
CWDM that optically demultiplexes the six video rack cards used in the RR-94800C-SL is
labeled MRX-CWDM-8. Mounting procedures and recommendations should follow those used
for the RT-94800C-SL.
POWER SOURCE
Power to the 980C series rack cards is supplied by the subrack. Please refer to the SR-20 and
PSR-2 instructions for further details.
POWER CONNECTION
Power is supplied to the individual 980C series via a four finger backplane connector. The
individual components can be inserted into the subrack or removed from the subrack with power
applied to the backplane. Please refer to the SR-20 and PSR-2 instructions for details.

RT-94800C-SL FIBER CONNECTIONS
The fiber optic connection to the user’s infrastructure is made via a SC connector located at the
back of the CDWM unit next to the power input. Be sure to allow sufficient room for the required
minimum bend radius of the fiber cable used. SC patchcords are supplied for the intra-fiber
connections between the CWDM and each of the 980C series units. The wavelength listed for
each port on the CWDM must correlate with the wavelength listed on the 980C series unit to
which that port is attached.

VIDEO INPUT / OUTPUT CONNECTIONS
Video input and output connections are located on the rear of the 980C series units. 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.
The location of a video input to the RT-94800C-SL will be mirrored as a video output at the RR-
94800C-SL. For example, the Channel 2 video input on the RT-980C-1550 will become the
Channel 2 video output on the RR-980C-1550 after traveling across the fiber infrastructure.
