FI-500 FiberInspector™ Micro-Fiber Optic Endface Inspection Scope with PortBright™ Illumination

Download PDF


Dirty fiber optic endfaces are the major cause of problems in singlemode and multimode fiber optic systems.

The FI-500 FiberInspector™ Micro removes the hassle associated with inspecting fiber endfaces, especially in low light and high cable density situations.

It is very simple to use:

Simply plug the cable into the FI-500 and touch the AF button. Within seconds, the fiber endface comes into sharp, clear view. And if you're working in a difficult to reach place or you can't get the image to stand still, just touch the pause button to freeze the image.

Just right for Troubleshooting

Today's high density fiber patch panels make inspection a challenge. Finding the cable or port to test can be tough, especially in the low light conditions found in most data centers and wiring closets.

The FI-500 is designed to simplify the inspection process. The built-in PortBright flashlight helps you find the right port or cable. The small-profile probe fits into tight spots, and features pushbutton controls for simple operation. Autofocus provides a sharp view of the endface in under a second, while the pause button freezes the image on the crisp 320 x 240 display for more detailed inspection.

The FI-500 FiberInspector Micro fills the gap between a manual scope and a fully automated inspection scope. The FI-500 has the simplicity and practicality of a manual inspection scope, but with advanced features to reduce troubleshooting and inspection time.

Manual fiber inspection scopes are simple to use, but they don't work well on patch panels or situations where there is a high density of fiber. Holding it up to one eye and closing your other eye is often inconvenient or impractical, especially in a dark room.

Fully automatic inspection scopes analyze and grade the cleanliness of fiber connections which is important for many applications, but analysis is usually not needed for quick basic troubleshooting.

Fiber Inspection and Cleaning

Dirt, dust and other contaminants are the enemies of high-speed data transmission over optical fiber. Today's network applications require more bandwidth than ever, making loss budgets tighter than ever. Hence, it is critical that all optical connections are free of contaminants to avoid having application performance issues.

Eliminate the #1 cause of fiber failure

In a survey of installers and network owners commissioned by Fluke Networks, endface contamination was found to be the leading cause of fiber failures. Dirt and contaminants cause insertion loss and back-reflection that inhibit the light transmission and raises havoc with transceivers. And because dirt can migrate from one endface to another upon mating, both sides of any connection must be inspected. Further, mating contaminated connectors can cause permanent damage as microscopic debris is crushed between endfaces in physical contact. Therefore, you must always inspect and clean before mating as a preventative measure and not only after experiencing problems. Even factory terminated patch cords or pigtails must be inspected as protective caps do not keep endfaces clean. Avoiding this common cause of failure starts with inspecting the endface and eliminating any contamination before insertion into a bulkhead or piece of equipment.

Range of inspection options

With a range of solutions, Fluke Networks always has the right tool for you to easily inspect endfaces on a wide variety of connectors.
