instructions<br />
Manufacturer instructions:<br />
Refer to the manufacturer’s optical inspection instructions. The following<br />
steps can be used as a guideline:<br />
Make sure that the fiber link to be examined is not actively transmitting. This is<br />
accomplished by physically detaching the connectors from the transmitter or turning<br />
off the power of all interface equipment. Protect equipment against re-connection or<br />
power on during inspection.<br />
Serious eye injury can occur during the inspection of a<br />
connector if an active transmitter is connected to the fiber<br />
Always verify that the connector under inspection is not attached<br />
to a transmitting source.<br />
Notice that the wavelengths 850nm <strong>and</strong> 1300nm, used <strong>for</strong> the<br />
optical transmission, are not visible <strong>for</strong> the human eye!<br />
