Page 7: Background
BACKGROUND As human society, the role of information in our daily lives grows in importance. It has been said that we are entering the “information age”. In the past century, electronic means of communications such as radio, telephone and television have become dominant because of their ability to send information quickly over large distances. -

LED Activation The “LED ACTIVATION” push-button is a momentary switch which turns on the built- in LED source for approximately 10 minutes, after which the LED turns off to conserve battery life. Wavelength The “WAVELENGTH” slide switch adjusts the sensitivity of the radiometer at two factory calibrated wavelengths, 650 nm (visible red) and 850 nm (near-infrared). -

2.2 mm. For best results, the cable end should be prepared by cutting with an appropriate tool such as those available from Industrial Fiber Optics. When measuring an un-connectorized fi ber or cable with a diameter smaller than 2.2 mm, some type of sleeve should be used to make up the difference. -
Page 15: Measuring Power From A Fiber Optics
Measuring Power from a Fiber Optic Cable Overview One of many important measurements in the fi ber optic industry is that of optical power. Transmitting information using fi ber optic links depends on suffi cient optical power traveling through the optical fi ber, connectors, and other elements in which light could be lost. - Page 16 SE T FI BE R OP TI C TE ST Figure 2.

Page 17: Measuring Attenuation In Optical Fiber
Measuring Attenuation in Optical Fiber Overview Fiber optic cables offer many advantages over copper cables, including lighter weight, higher information carrying capacity, and lower signal loss. Eventually as light travels through a fi ber some optical signal loss or attenuation does occur. The two main causes of optical attenuation are scattering and absorption. - Page 18 DISPLAY SELECTOR SWITCH ACTIVATION LED TURNS OFF AFTER 10 MIN.

- Page 19 Turn the test set off by pressing the “ON/OFF” switch and remove only the cable attached to the “DETECTOR” receptacle. If you are using an external source, turn it off to ensure eye safety during the next steps. For the plastic fi ber, measure a distance of fi ve meters (5 m) from the unconnected end of the cable, then cut it squarely with a single edge razor or a tool such as the IF-FC1.

Page 20: Logarithms/Db Measurement Units
LOGARITHMS/DB MEASUREMENT UNITS Some instruments have a display that responds in a logarithmic scale, where the measurement is related numerically to the base 10 logarithm (Log) of the change in optical power. For example, a radiometer has an input power of 1 mW (a reference level in the fi... -
Page 21: Troubleshooting
Do not attempt to troubleshoot the Fiber Optic Test Set beyond the steps listed above. If you believe that a problem exists within the Fiber Optic Test Set, please either contact the factory or return it for appropriate servicing to Industrial Fiber Optics, as described in the section titled SERVICE AND MAINTENANCE. -
Page 22: Service And Maintenance
The only service and maintenance that the Fiber Optic Test Set should require is battery replacement, “zeroing”, and LED power adjustment. Instructions for these procedures follow. All other adjustments have been made by Industrial Fiber Optics. Battery Installation Procedure The recommended batteries for the Fiber Optic Test Set are standard, heavy-duty or alkaline 9-volt batteries. -

allow one minute for the source to stabilize. Note if the reading on the display is within ± 10% of the test cable calibration value. A reading outside this range can be caused by drift of the LED from aging or large changes in room temperature. To restore the factory setting or establish a different power level proceed with the following steps. -
