Fiber Optics Cable Field Calibration and Testing<br />
FIELD CALIBRATION (GENERAL)<br />
Field calibration allows the FIBERTEK to obtain a reference level for loss measurement.<br />
The accuracy of the field calibration depends on the amount of warm-up time allowed<br />
prior to starting the calibration process.<br />
Figure 5-2: Preferred Setup for Field Calibration<br />
Note: Allow the adapter a proper warm up time prior to field calibration. This will<br />
ensure specified accuracy. Be sure the launch cables are the same type of fiber as<br />
the cable being tested. (i.e. 50μm jumpers to test 50μm cabling)<br />
If the FIBERTEK unit has been stored in a location substantially colder than the area<br />
where measurements are to be taken, allow the unit to warm up to the ambient<br />
temperature with the protective dust caps in place to prevent condensation on the<br />
transmitter or receiver diode lenses.<br />
Thoroughly clean the laser and receiver lenses prior to attaching the launch cables<br />
using the Fiber Cleaning package supplied with your Basic or Premium Kit, which<br />
contains a high-quality cleaning solution and lint free wipes. Contact your local<br />
distributor for refills.<br />
Replace dust caps immediately after launch cables are removed.<br />
The setup depicted on this page is the normal calibration configuration for all tests<br />
that use both handsets. This includes Autotest as well as the Attenuation and Length<br />
tests, which are accessed through the Analyze menu. Calibration configuration for<br />
Loopback Attenuation is described later in this manual.<br />
The calibration data is recorded and stored by the Display Handset. The loss effects of<br />
launch cables and couplers that were present during field calibration are subtracted<br />
from the attenuation results during testing.<br />
