What Is a Fiber Optic Continuity Tester? Fiber Optic Technology Tutorial, Series Two

What is a fiber optic continuity tester?

Fiber continuity tester is also known as fiber optic continuity checker. It is the most simple visible check of a fiber optic cable hyperlink.

To serve as correctly, a fiber optic cable hyperlink will have to be “steady”, which means no breakage, both inside the fiber cable or within the fiber connectors, must exist. The most straightforward and least pricey solution to take a look at is to inject some visible mild into one fiber finish and take a look at the sunshine popping out from the opposite finish.

To carry out this process, two forms of fiber testers are to be had: a fiber optic continuity tester or a laser visible fault locater.

Differences between a fiber continuity tester and a laser visible fault locator

The maximum vital distinction is their mild supply. A fiber continuity tester generally makes use of a pink or inexperienced colour prime depth LED whilst a laser visible fault locator makes use of pink colour semiconductor laser.

Visible lasers produce a extra tough mild and may give additional information to the technician than a LED mild. By coupling the fiber hyperlink to a visual laser, issues of connectors, breaks within the fiber close to connectors or splices, and a few bend radius violations can also be positioned.

On the opposite hand, LED powered fiber continuity tester can best check that mild can shuttle during the fiber hyperlink and not more knowledge is got. Fiber continuity tester merely yields a “no cross” end result. If the sunshine is not visual on the different finish of the fiber hyperlink, then the fiber is unusable in its provide state and calls for additional checking out and service.

Applications of a fiber continuity tester

Its highest software is checking out fiber on a reel sooner than you pull it to verify it hasn’t been broken throughout cargo. Look for visual indicators of wear and tear (like cracked or damaged reels, kinks within the cable, and so forth.)

The different excellent software is to test fiber patch cables at patch panels. When connecting fiber cables at patch panels, use the fiber optic continuity tester to verify every connection is the appropriate two fibers!

And to be sure the correct fibers are hooked up to the transmitter and receiver, use the continuity tester instead of the transmitter and your eye as an alternative of the receiver.

Understanding the options of a fiber continuity tester

1. Fiber mode compatibility

Some fiber continuity testers best beef up multimode fibers whilst the others beef up each unmarried mode fibers and multimode fibers. So it is best to test the spec sheet from producers to make a choice the sort you wish to have.

2. Fiber connectors supported

Most fiber continuity testers have adapters to be had for checking out 2.5mm ferrule connectors reminiscent of ST, SC and FC, 1.25mm ferrule connectors reminiscent of LC, MU and particular sorts reminiscent of SMA connectors.

3. Fiber distance

Most fiber continuity testers have sufficient mild energy to beef up 2km on multimode fibers.
