What is a fiber optic continuity tester?
Fiber continuity tester is also called fiber optic continuity checker. It is the simplest optical test of a fiber optic cable link.
Cable Tester
To function properly, a fiber optic cable link must be "continuous", meaning no breakage, either within the fiber cable or in the fiber connectors, should exist. The simplest and least costly way to check is to inject some optical Light into one fiber end and check the Light coming out from the other end.
To achieve this task, two types of fiber testers are available: a fiber optic continuity tester or a laser optical fault locater.
Differences between a fiber continuity tester and a laser optical fault locator
The most important distinction is their Light source. A fiber continuity tester typically uses a red or green color high intensity Led while a laser optical fault locator uses red color semiconductor laser.
Visible lasers yield a more considerable light and can contribute more data to the technician than a Led light. By coupling the fiber link to a graphic laser, problems with connectors, breaks in the fiber near connectors or splices, and some bend radius violations can be located.
On the other hand, Led powered fiber continuity tester can only verify that light can voyage through the fiber link and no more data is obtained. Fiber continuity tester naturally yields a "no go" result. If the light isn't graphic at the other end of the fiber link, then the fiber is unusable in its gift state and requires further testing and repair.
Applications of a fiber continuity tester
Its best application is testing fiber on a reel before you pull it to make sure it hasn't been damaged while shipment. Look for graphic signs of damage (like cracked or broken reels, kinks in the cable, etc.)
The other good application is to check fiber patch cables at patch panels. When connecting fiber cables at patch panels, use the fiber optic continuity tester to make sure each relationship is the right two fibers!
And to make determined the allowable fibers are linked to the transmitter and receiver, use the continuity tester in place of the transmitter and your eye instead of the receiver.
Understanding the features of a fiber continuity tester
1. Fiber mode compatibility
Some fiber continuity testers only retain multimode fibers while the others retain both particular mode fibers and multimode fibers. So it's best to check the spec sheet from manufacturers to select the type you need.
2. Fiber connectors supported
Most fiber continuity testers have Adapters available for testing 2.5mm ferrule connectors such as St, Sc and Fc, 1.25mm ferrule connectors such as Lc, Mu and extra types such as Sma connectors.
3. Fiber distance
Most fiber continuity testers have adequate light power to retain 2km on multimode fibers.
