Fiber Information
This unit was manufa c tured with attention to fiber cleanliness by Optelecom-NKF. Beyond the optical safe t y
i n formation contained in this manual, the fo l l o wing 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 9225DT transmitter accepts a composite video signal in NTSC, PAL, or SECAM format via the BNC video
input port. This baseband video signal is sampled at a 16 mHz rate by an A-to-D converter operating with nine
bits of precision. Data signals are combined into the bit stream and converted to an optical signal for
transmission over the optical fiber.
The receiver accepts the optical signal and converts it back to a serial bit stream. The signal is deserialized
and converted back into the video and data signals, which are output on the BNC and data connectors.
Data in the reverse direction is converted to an optical signal by the receiver at a different wavelength and
sent over the fiber to the transmitter where it is decoded and converted back to the data format for output.
The 9225DT and 9225DR are compatible with the 9221DT and 9221DR rack-mount models.
The 9225DT and 9225DR operate on 8 to 15 VDC from the 9014PS or other DC power supplies. The 9225DT
is also available in an18 to 30 VAC or VDC version. Add –AC to the model number.

Set Up and Operation of the 9225DT and DR
Operation of the 9225DT and 9225DR units consists of setting the data parameter switches as required,
installing the card in a compatible Series 9000 chassis, connecting the optical cables, the video input, and the
data signals.
PTZ/DATA CHANNELS SWITCH SETTINGS AND CONNECTIONS
The PTZ data channel switch sets the data input and output formats. Refer to Table 1 and the input/output

Troubleshooting 9225D Links
Troubleshooting 9225 links is usually started at the transmitter end. At least one of the indicators should be
illuminated, indicating that power is applied to the unit.
The Video Present indicator illuminates when a video signal is present on the input BNC connector. If this is
not green, check the incoming video source.
The Loop, Sync and Not Sync indicators are used together to troubleshoot fiber and other problems. If the
loop indicator is illuminated, both local and remote units are communicating correctly. If the Sync indicator is
illuminated, but not the Loop, the remote unit is not synchronized with the local unit. Check the fiber for
optical losses above the specifications.
Should the Not Sync indicator be illuminated (red), the local unit is not receiving sufficient optical signal from the
remote unit or the local demux circuitry is not able to synch r o n i ze to the incoming signal. Check the fiber fo r
losses or the remote unit for powe r.
The RD indicator can help troubleshoot the data channel. When any data is received, this indicator will flash. If
data is not being received, check to make sure the data interface has been configured properly to receive the
type of data connected.
