Fiber Information

This unit was manufactured with attention to fiber cleanliness by TKH Security Solutions USA. 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. Do not use isopropanol alcohol (typically called rubbing alcohol) mixed with water. This can cause

additional spots. (Caution:

b. Use lintless tissues to clean fibers.

Pure isopropanol is very flammable!

)

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,

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.

always

clean them when replacing them no matter how long you had them off.

Functional Description

The TKH Security USA Model 9522A is an RS232, RS422, and RS485 compatible fiber optic standalone modem
with dual electrical I/O ports and dual optics for drop and insert applications that can be configured in a wide
range of poll/response network architectures. The unit operates using only one fiber for transmit and receive
in the upstream direction and a second fiber in the downstream direction. This results in the formation of a
single fiber daisy chain or loop.

The units have four switch-selectable modes of operation: Master Fault Tolerant mode (MFT), Local Fault
Tolerant mode (LFT), Master Daisy Chain mode (MDC), and Local Daisy Chain mode (LDC). See the
Installation section for a complete description of these modes of operation.

Each modem has two full function data I/O ports (Primary and Secondary), allowing it to serve two terminal
units at a single location without the need for a second modem. Each of these ports can also interface with
another modem to establish branches off the main trunks or even off other branches. The modem has a
unique feature in that it is able to tag data originating from it when operating in local mode and separately tag
the data from master and local modems. The result of this feature, which identifies the data source, is that the
master only receives data from the locals and the local only receive the data from the master.

The units have ten LED indicators. Power and various fault and status indicators provide information on the
electrical status of the I/O ports, fiber status, redundant ring status, and other possible conditions. A built-in,
offline Bit Error Rate Test (BERT) with indicator LED can help troubleshoot the system. Six of the indicators
serve dual functions as selected by the SELECT switch. In one position the LEDs indicate electrical side signal
activity and CTS status. In the other position the LEDs indicate fiber port activity as well as the active fiber
input port as chosen by the priority select circuitry.

Dipswitches allow the user to select one of the four operating modes (BERT test enable, the communications
interface for each data I/O port, and the timeouts for the optical and electrical side anti-streaming), the fiber
activity CTS inhibit (RS232 mode), the Priority Select Timeout, the electrical Ring Propagation delay, Echo
Cancel, and the “Data Tagging” selective routing feature. These are explained in the Installation section.

The unit operates on 6VDC supplied from the chassis backplane and is compatible with the Network
Management System software for monitoring and troubleshooting TKH Security USA fiber optic transport
systems.

The 9522A modem is optically compatible with the Models 9526A and 9525A standalone drop/insert modems.
