Fiber Optic Length Testers

The BOLT (Beaming Optical Length Tester) is a low-cost alternative for users who need to measure the length of optical fibers.

The BOLT-NL uses a "looped" method of measuring fiber length. This is accomplished by looping back two fibers at one end of the fiber run with a patch cord. The round trip time that the light takes to travel through the fibers is converted to length in kilometers, then divided by two to show the length of the fiber cable. There is no need to measure the length of all the fibers; the length measurement can be applied to all fibers in the cable. This method of length testing provides accurate measurements, and saves time and money.
