Fiber Information
This unit was manufactured with attention to fiber cleanliness by Optelecom-NKF. Beyond the optical safety
information contained in this manual, the following guidelines should be observed when working with
optical fibers.
The biggest problem is dirt!
It takes very little contamination to cause problems with optical fiber connections; cleanliness is extremely
important to proper operation of optical equipment.
1. Protect optical connectors by leaving the connector covers in place on unused fiber connections and on
the fiber tips themselves.
2. Personnel who remove and replace fibers should be equipped with a fiber cleaning kit. These are
inexpensive and can be obtained from any fiber equipment supply house. If you choose to, you can use
propanol and lint-free tissue to clean fibers.
a. a. Do not use isopropanol alcohol (typically called rubbing alcohol) mixed with water. This can cause
additional spots. (Caution: Pure isopropanol is very flammable!)
b. Use lintless tissues to clean fibers.
c. Clean the fiber with a folded tissue moistened with the propanol, pulling the connector tip across the
tissue, then turn the connector 90 degrees and repeat in a different spot on the tissue.
d. Don’t pull the fiber across and then push it back. This will put the dirt that was cleaned off back on
again.
e. Repeat the process on a dry, folded tissue.
3. When removing fibers, always clean them when replacing them no matter how long you had them off.
4. When connecting fibers, pay attention to the bend radius of the fibers. A general rule is to have a 3-inch
(8 cm) bend radius. A bend radius less than 3 inches is an attenuator and can cause optical signal loss.
5. Installers of fiber equipment should be equipped with the equipment manuals and an optical power meter
to measure the optical inputs and outputs in a system. An optical power meter is an inexpensive tool that
can save much time and effort in getting optical communications links up and running. Properly equipped
and trained installers can quickly determine the source of any problems that occur.

Functional Description
The 9191DT transmitters accept two composite video signals in NTSC or PAL format via two BNC video input
ports. The baseband video signals are each sampled at a 16 Mhz rate by an A-to-D converter operating with
nine bits of precision. The nine bits of digitized video and one high-speed data signal are multiplexed,
serialized, and converted to an optical signal for transmission over the fiber.
The 9191DR receiver accepts the optical signal, converts it to an electrical signal, then deserializes it and
demultiplexes it into two digitized video and one high-speed data stream. The digitized video is converted
back to the two original video signals via D-to-A converters.
9191DT and DR cards are optically compatible with the 9195DT and DR standalone modules.
The simplex high-speed port on the 9191DT and 9191DR cards, which operate in the same direction as the
video, transport synchronous 16 Mbps or 1.6 Mbps asynchronous RS422 data. This port is designed to
operate with the 9961-C and 9962-C option module host cards and other cards that add data, audio, and
contact closure transmission capabilities to Optelecom video transmission systems.
The cards operate on 6 VDC as supplied by the chassis into which it is installed.

This LED illuminates green when the received optical signal quality is sufficient and the receiver can
properly decode the electrical signal. If illuminated red, the optical signal is too low or the electrical signal
cannot be decoded properly.
2. OPTICAL INPUT CONNECTOR
The input optical connection is made here.
3. CHANNEL 1 AND CHANNEL 2 VIDEO OUTPUT CONNECTOR
These BNC connectors provide the outputs for the two video signals.
4. CHANNEL 1 AND CHANNEL 2 TX VIDEO PRESENT INDICATOR
This LED illuminates green when the transmitter reports that a valid video signal is connected to the
respective input BNC of the transmitter card. This duplicates the operation of the Video Present indicator
at the transmitter end.
5. HIGH-SPEED PORT CONNECTOR
This RJ45 input connector is the output for the high-speed port.

Set Up and Operation of the 9191D
Set up and operation of the 9191DT and DR units consists of installing the unit into a Series 9000 series
chassis, then connecting the optical cables and the video input and output signals. There are no switches
to set or adjustments that can be made on this unit.
High-Speed Port Operation
The high-speed port carries 16 Mbps simplex synchronous RS422 data. The port may be used asynchronously
at speeds of up to 1.6 Mbps. It is designed to interface with the 9961-C and 9962-C option module host cards
or other cards that may become available for operation with the high-speed port. The 9961-C and 9962-C
allow the addition of up to eight simplex data, contact closure, or stereo audio channels to the two video
channels already on the fiber.
The ports are wired as shown in Figures 3 and 4 and in Tables 1 and 2 below. The 9961-C and 9962-C cards
are normally supplied with a properly configured cable for connection to a high-speed port. A standard (not
crossover) RJ45 CAT5 cable will also work correctly. Cable lengths should not exceed 1.3 meters (4 feet).

Troubleshooting the 9191D
The indicator LEDs on the transmitter and receiver provide information as to the
optical and electrical status of the units. Troubleshooting normally starts at the transmitting end.
On the 9191DT transmitter, the power indicator should be illuminated; if no indicators are illuminated, check
the chassis power supply, power source, and connections.
When video is applied, the Video Present indicator should be illuminated green. If the Video Present indicator
is not green, then check the video source and connections.
On the 9191DR receiver, the status indicator should be illuminated either red or green; if no indicators are
illuminated, check the chassis power supply, power source, and connections.
When the STATUS indicator is illuminated green, operation is normal. The STATUS indicator will be illuminated
red to indicate insufficient optical signal at the optical input. Check the fiber for poor connections or optical
losses greater than the unit specifications.
If the STATUS indicator is illuminated green and the TX Video Present indicator is not illuminated, the video
source at the transmitter end should be checked.
