With multimo<strong>de</strong> fiber, the signal can be transmitted in different “mo<strong>de</strong>s.”<br />
The modal bandwidth is a measurement of the ability of the fiber cable<br />
to pass the signal without adding additional attenuation. Modal<br />
bandwidth is a rating given to the fiber. The fiber manufacturer should<br />
be able to tell what the modal bandwidth of their fiber is. You should<br />
then select the proper Modal Bandwidth in the <strong>WireScope</strong> <strong>350</strong> before<br />
running the test. To set the modal bandwidth for optical fiber<br />
certification:<br />
1 On the Fiber Autotest Settings screen, press Modal BW, then Edit.<br />
The Modal BW Setup screen displays.<br />
2 Choose the modal bandwidth and press OK. The Fiber Autotest<br />
Setup screen displays, with the chosen bandwidth next to Modal<br />
BW.<br />
Choosing the Connector Type<br />
Connectors of different types have different transmission<br />
characteristics. The <strong>WireScope</strong> <strong>350</strong> compensates for those differences, if<br />
you tell it what connectors are used on the job.
