The VFL 5000 is used for continuity testing and fault location on optical fibers and components in singlemode and multimode area is used. Depending on the application, a range of more than 5 km can be achieved. A universal adapter enables the Connection of all common 2.5 mm optical connector systems. An adapter for 1.25 mm is also available. The operating time is in flashing mode approx. 40 hours.

Due to its compact and robust design, the visual error detector is ideal for daily use. Use in all fiber optic applications, e.g. in data centers, outdoors, in industrial applications environments, as well as in laboratories. The Visual Fault Locator from Softing IT Networks is characterized, among other things, by with several practical features, such as its special, roll-resistant shape, the cap that is captive against dust and impact and its extremely robust housing. The Visual Fault Locator can be easily and with only one hand and is powered by AAA standard batteries. The practical holder makes it easy to hang up the VFL at any time.
