What is a fiber optic cable tester?
A fibre optic cable tester is a hand-held troubleshooting expedient that sends red Light from a semiconductor laser (635nm) down a fiber to check for faults such as cracked fibers or defective splices.
Cable Tester
The graphic red Light travels along the fibre core until it reaches a fault, where it leaks out of the fiber. Light leaking straight through the fault can be seen straight through plastic coatings and jackets under favorable illumination. Infrared light in the signal leaks out at the same point, but your eyes cannot see it. The tester emits Class Ii red laser beam, development the light escaping from the damaged fiber assuredly graphic from a distance.
Attenuation of glass fibres is much higher at 630 to 670nm wavelengths of red light than in the 1300 to 1650nm transmission window, but the red light can still voyage up to 5km straight through thorough fibers. Note that the fibers must be exposed to use fiber optic cable tester effectively. If the red light leaks out inside a thick cable wrapped in black plastic, you can't see it.
This technique is particularly requisite in equipment bays and other places inside buildings where fibres are exposed.
Shining a flashlight beam down a multimode fiber can serve the same function, and has long been used to trace fiber continuity as well. However, the flashlight couples puny light into a singular mode fiber.
Whether installing or troubleshooting, the fiber optic cable tester is an requisite tool that fast and assuredly locates question areas in fiber cables. By pinpointing the exact location of fiber damage, technicians can diagnose, troubleshoot, and fix the question effectively. The cable tester is also used for conducting continuity tests and performing fibre identification.
The Continuous/Flash operate button lets operators choose between continuous or flashing illumination.
Applications
Fiber optic cable tester can be used to find sharp bends, breaks, and damages in fibre. It can also escort end-to-end continuity tests. The other function is to accomplish fibre tracing and identification.
What types of tester are available?
There are two unique versions of fiber cable tester that are ergonomically designed for comfortable handling and portability. Both versions are adequate with a 2.5mm interface and are compatible with connectors such as Sc, St, and Fc, while the 1.25mm Adapter enables relationship to Lc and Mu connectors.
To ensure ruggedness, it features rubber seals, a fully enclosed laser head and a long-lasting On/Off switch. It has been tested to provide trustworthy execution under oppressive use and harsh conditions.
