Frequently Asked Questions About Fiber Optic Testing Tools
What is the difference between an Optical Power Meter (OPM) and an OTDR?
An Optical Power Meter (OPM) is used alongside a light source to measure the absolute power of the optical signal and overall insertion loss in a fiber link. An OTDR (Optical Time Domain Reflectometer), like our 45dB NK6800, is a much more advanced diagnostic tool. It acts like “fiber radar,” shooting light pulses into the cable to pinpoint the exact location and distance of breaks, splices, and high-loss bends.
How do I choose the right Visual Fault Locator (VFL) power output?
The power of the VFL determines how far the visible red laser can travel through the fiber. A standard 10mW VFL is typically sufficient for short-distance tracing up to 10-15 kilometers, ideal for indoor data centers. For long-haul telecommunication lines, we highly recommend a 30mW high-power VFL, which can illuminate breaks and micro-bends up to 50 kilometers away.
Are E-link Fusion Splicers suitable for outdoor FTTH deployment?
Absolutely. Our fusion splicing machines, such as the K6 and M5 series, are designed specifically for rugged field environments. They feature 6-motor core-to-core alignment for extreme accuracy and are equipped with high-capacity lithium batteries (e.g., 7800mAh) that support hundreds of splicing and heating cycles on a single charge. Many models also include built-in OPM and VFL functions, reducing the amount of gear you need to carry on-site.
