Fiber Optics Diagnostics (TRACETEK)<br />
TROUBLESHOOTING WITH TRACETEK<br />
TRACETEK can be an invaluable tool for troubleshooting a variety of network<br />
problems. One application is to locate a break in a cable. In a new installation,<br />
TRACETEK can be used with a power meter/light source test kit such as FIBERTEK to<br />
characterize a link and map the distance to known events.<br />
In this example we’re testing a backbone link consisting of 44 m of cross-connect<br />
cable to a 717 m backbone, followed by another 40 m of cross-connect. Figure A is the<br />
FIBERTEK (power meter/light source) result from the link indicating a passing result.<br />
In Figure B, we see the connectors at 40 m and 760 m, as well as the end of the fiber<br />
at 801m. The connectors at 40 m and 760 m appear to be in good condition with a<br />
reflection that is just below half scale.<br />
Figure A<br />
Figure B<br />
Figures C and D show the same link failing. The FIBERTEK screen tells the degree of<br />
link failure but it does not help isolate the problem. TRACETEK screen (Figure D)<br />
shows the connector at 761 m is nearly full scale, an indication that it has become<br />
dirty or damaged.<br />

In this situation, the best course of action is to clean the connection at 760 m and<br />
check it with a microscope (IDEAL P/N 45-332) before re-testing. Consult the<br />
instructions included with the IDEAL Starter Cleaning Kit for the best methods to clean<br />
connectors and couplers.<br />
