INSTALLATION AND OPERATION INSTRUCTIONS
INTRODUCTION
Thank you for purchasing your American Fibertek Series 94085SL singlemode forty channel
video multiplexer with bi-directional multi-protocol data. Please take a few minutes to read these
installation instructions in order to obtain the maximum performance from this product.
FUNCTIONAL DESCRIPTION
The 94085SL Series units operate as a transmitter / receiver pair for the digital transmission of
forty simultaneous NTSC or PAL video signals along with two channels of field configurable bidirectional data over one singlemode fiber optic cable. These data channels may be configured
as RS485 data, RS422 data, RS232 data, or Manchester data. The RS485 channel may be
configured for 2-wire (half duplex) or 4-wire (full duplex) with or without biasing. Switch
selectable internal 120 ohm terminations are available for RS422 or RS485 data.
NOTE: This unit is shipped with Data Channel 1 and Data Channel 2 in the RS485 4-wire
configuration. For other configurations, please refer to the DATA MODE section for
changes to the default switch settings.
NOTE: This unit is shipped with data terminations off and data bias off for Data Channel
1 and Data Channel 2. For other configurations, please refer to the DATA TERMINATION /
BIAS section for changes to the default switch settings.
The RT-94085SL transmitter accepts up to forty video inputs in five 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 five
using wavelengths 1550nm through 1590nm respectively. A Course Wave Division Multiplexer
(CWDM) combines these five 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-94085SL receiver converts the optical
signal into forty independent video output signals and two forward data channels while
transmitting the two return data channels.
The 94085SL 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-94085SL COMPONENTS
The RT-94085SL consists of the following components:
1) RT-980-1510 1) RT-980-1570 1) SR-20 1) PSR-2
1) RT-980-1530 1) RT-980-1590 5) PCSC/UPC-0.3 2) BPS-2
1) RT-980-1550 1) MTX-CWDM-8-MPD
The individual 980 series video rack cards that make up the RT-94085SL 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 the
lowest wavelength card, the RT-980-1510, next to the PSR-2 power supply and ends with the
highest wavelength card, the RT-980-1590, 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 five
video rack cards used in the RT-94085SL is labeled MTX-CWDM-8-MPD. 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-94085SL components.

RR-94085SL COMPONENTS
The RR-94085SL consists of the following components:
1) RR-980-1510 1) RR-980-1570 1) SR-20 1) PSR-2
1) RR-980-1530 1) RR-980-1590 5) PCSC/UPC-0.3 2) BPS-2
1) RR-980-1550 1) MRX-CWDM-8-MPD
The individual 980 series video rack cards that make up the RR-94085SL are installed in a
manner similar to the RT-94085SL (see drawing below). The Multi-Channel Digital Video
CWDM that optically demultiplexes the five video rack cards used in the RR-94085SL is labeled
MRX-CWDM-8-MPD. Mounting procedures and recommendations should follow those used for
the RT-94085SL.

POWER SOURCE
Power to the 980 series rack cards is supplied by the subrack. Please refer to the SR-20 and
PSR-2 instructions for further details.
Power for the CWDM units is generated by an internal power supply which 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
Power is supplied to the individual 980 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 supplied (in the US and UK only) with a three conductor power cord. The
“ground” conductor is directly connected to the chassis.
