GENERAL
This manual is a guide to the installation and operation of the
S703V and S7703V series fiber optic two-channel video multi-
plexer systems. Please read the entire manual before installing
the equipment.
These two-channel video multiplexers offer simultaneous trans-
mission of two full-frame video signals (color or monochrome).
The S703V units use multimode fiber while the S7703V units
operate over single-mode fiber.
Note:
The series numbers S703VT and S703VR will be used to
describe all models of transmitters and receivers unless noted
otherwise.
A complete system consists of a transmitter, S703VT, and a
receiver, S703VR. Units are designed for standalone operation
or for installation in Fiber Options’ 515R1 or 517R1 Card
Cages or 501R miniature enclosures. The S703VT transmitter
has two video inputs and one fiber output. The S703VR receiv-
er unit has one fiber input and two video outputs.

1 INSTALLATION
1.1 INSTALLATION CONSIDERATIONS
This fiber-optic link is supplied in two forms, as a stand-
alone module and as a rack card. Units should be
installed in dry locations protected from extremes of tem-
perature and humidity.
1.2 STANDALONE MODULES
Determine where the module is to be installed and
ensure that there is adequate space at both ends for
making the various cable connections and for reading the
diagnostic LEDs.
Standalone modules are provided with mounting holes
for four No. 6 screws (3-mm or 3.5-mm screws). The
type of screw chosen must be suitable for the surface on
which the module is to be mounted.
Some standalone modules consist of a rack card
installed in a standalone enclosure and are mounted in
the same manner. The rack card is normally installed in
the enclosure at the factory.
1.3 RACK CARDS:
Rack cards are designed to be installed in one of Fiber
Options’ 19-inch (483-mm) EIA standard card-cage
racks, either the 515R1 or the 517R1. They may also be
supplied in the 501R standalone rack-card enclosures.
1.3.1 515R1 AND 517R1 CARD CAGE RACKS
To install rack cards in a rack, follow these steps:
CAUTION:
Fiber Options recommends that the power
switch on the rack power supply be turned OFF and that
the rack power supply is disconnected from any power
source.
Make sure that the card is oriented right-side up, and
slide it into the card guides in the rack until the edge con-
nector at the back of the card seats in the corresponding
slot in the rack’s connector panel. Seating may require
thumb pressure on the top and bottom of the card’s front
panel.
CAUTION:
Take care not to press on any of the LEDs.
Tighten the two thumb screws on the card until the front
panel of the card is seated against the front of the rack.
1.3.2 501R STANDALONE ENCLOSURES
To install rack cards in standalone enclosures, follow
these steps:
CAUTION:
The rack card module can ONLY be powered
by 13.5-16 VDC. AC power must not be used.
