INSTALLATION AND OPERATION INSTRUCTIONS
INTRODUCTION
Thank you for purchasing your American Fibertek Series 94845SL singlemode forty-eight
channel video multiplexer with bi-directional Ethernet data. Please take a few minutes to read
these installation instructions in order to obtain the maximum performance from this product.
FUNCTIONAL DESCRIPTION
The 94845SL Series units operate as a transmitter / receiver pair for the digital transmission of
forty-eight simultaneous NTSC or PAL video signals along with one channel of bi-directional
Ethernet data over one singlemode fiber optic cable. The Ethernet data channel will auto-
configure for a transmission speed of either 10 Mb/s or 100 Mb/s. An external switch is provided
for selecting MDI (straight) or MDIX (crossover) Ethernet connections.
The RT-94845SL transmitter accepts up to forty-eight video inputs in six 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 1510nm wavelength. The second group’s serial data stream
modulates a laser at 1530nm wavelength. This pattern is repeated for group’s three through six
using wavelengths 1550nm through 1610nm respectively. A Course Wave Division Multiplexer
(CWDM) combines these six wavelengths, along with the forward data wavelength of 1490nm
and the return data wavelength of 1470nm, onto a single optical output port for connection to
the fiber transmission system. Correspondingly, the RR-94845SL receiver converts the optical
signal to forty-eight independent video output signals and one data output while transmitting the
one return data channel.
The 94845SL 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-94845SL COMPONENTS
The RT-94845SL consists of the following components:
1) RT-980-1510 1) RT-980-1570 1) RTX-45-1490 1) SR-20
1) RT-980-1530 1) RT-980-1590 8) PCSC/UPC-0.3 1) PSR-2
1) RT-980-1550 1) RT-980-1610 1) MTX-CWDM-8 1) BPS-1
The individual 980 series video rack cards that make up the RT-94845SL 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 980 series rack cards can slide into any of the open slots in the SR-20 subrack,
however, the recommended configuration is shown below. This configuration starts with a blank
panel next to the PSR-2 power supply followed by the RTX-45-1490 data card. The lowest
wavelength video card, the RT-980-1510 continues the configuration which ends with the
highest wavelength card, the RT-980-1610, at the left side of the rack. Following this
configuration allows the fiber port on the back of the 980 series card to best line up with its
associated port on the CDWM 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 and one data rack card used in the RT-94845SL 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-94845SL components.

RR-94845SL COMPONENTS
The RR-94845SL consists of the following components:
1) RR-980-1510 1) RR-980-1570 1) RRX-45-1470 1) SR-20
1) RR-980-1530 1) RR-980-1590 8) PCSC/UPC-0.3 1) PSR-2
1) RR-980-1550 1) RR-980-1610 1) MRX-CWDM-8 1) BPS-1
The 980 series video rack cards and the data rack card that make up the RR-94845SL are
installed in a manner similar to the RT-94845SL (see drawing below). The Multi-Channel Digital
Video CWDM that optically demultiplexes the six video rack cards and the one data card used in
the RR-94845SL is labeled MRX-CWDM-8. Mounting procedures and recommendations should
follow those used for the RT-94845SL.

POWER SOURCE
Power to the 980 series and 45 series rack cards is supplied by the subrack. Please refer to the
SR-20 and PSR-2 instructions for further details.
The CDWM unit is a passive device which does not require any power source.
POWER CONNECTION
Power is supplied to the individual 980 series and 45 series units 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.
The CDWM unit is a passive device which does not require any power connection.

RT-94845SL 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 980 series and 45 series units. The
wavelength listed for each port on the CWDM must correlate with the wavelength listed on the
980 series unit to which that port is attached. The top port of the RTX-45-1490 connects to the
1470nm port on the CWDM. The bottom port of the RTX-45-1490 connects to the 1490nm port
on the CWDM. Follow the drawing below for the proper connections of the fiber patchcords.
RT-94845SL
RR-94845SL FIBER CONNECTIONS
The fiber optic connections on the RR-94845SL are similar to those for the RT-94845SL with
the exception of the RRX-45-1470 data card. On the RRX-45-1470, the bottom port connects
to the 1470nm port on the CWDM. The top port of the RRX-45-1470 connects to the 1490nm
port on the CWDM. Follow the drawing on the next page for the proper connections of the fiber
patchcords.

RR-94845SL
VIDEO INPUT / OUTPUT CONNECTIONS
Video input and output connections are located on the rear of the 980 series units. 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.
The location of a video input to the RT-94845SL will be mirrored as a video output at the RR-
94845SL. For example, the Channel 2 video input on the RT-980-1550 will become the Channel
2 video output on the RR-980-1550 after traveling across the fiber infrastructure.
ETHERNET DATA INPUT / OUTPUT CONNECTIONS
A RJ45 connector is used to connect UTP Ethernet data to the 45 series units.
MDI / MDIX Switch
All Ethernet equipment is designed with a MDI interface port or a MDIX interface port. The terms
MDI and MDIX refer to a specific orientation of the transmit data signal and the receive data
signal on the RJ45 connection to the unit. Some units have a switch built into them that allows
you to choose the port to be either MDI or MDIX. Other units can auto-configure to either speed.
Typically, a computer or terminal is wired as an MDI port connection and a network hub or
switch is wired as an MDIX connection. The MDI configured device is connected to the MDIX
device with a straight through Ethernet patch cable. Whenever a connection from one MDI
device to another MDI device is required, the use of a crossover cable is required to reorient the
signals, making the first device appear as if it was configured as MDIX. The RTX-45-1490 and
RRX-45-1490 are shipped in the MDI configuration. Therefore, when connecting to a MDI
configured device a crossover cable should be used. In the event the proper cable is not
available, an external switch is provided at the rear of the 45 series unit for reconfiguring the
unit as a MDIX port. If the 45 series unit is connected to an auto-configure device, it is not
necessary to change the MDI / MDIX switch.
