Power on the VFL. See page 18 for instructions on operating the VFL port.
Follow the steps below:
Connect the VFL port to the fiber under test. It is recommended to use a fiber patch cable as shown below to avoid handling
the fragile jacketed fiber in the splice tray.
do NOT insert an APC (Angled Physical Contact) connector in to the VFL port as this could damage the
angled ferrule on the APC connector.
The optional VFL port in the ZOOM 2 VFL can be used as a troubleshooting tool to determine if there are breaks, micro-bends, or any
other anomalies causing excessive loss within the first few feet of the fiber under test located in the splice tray. The bright red laser
injects high-intensity red laser light into the near-end connector. If this light encounters any anomalies, such as a break or a micro-
bend, the light is deflected into the fiber jacket, producing a red glow at the point of the anomaly.
