FAQs

A dead zone refers to the temporary period where the OTDR's internal detector is "blinded" by a strong reflective event (such as a fiber connector or a mechanical splice), making it unable to accurately measure subsequent closely spaced events.
There are two main types of dead zones:

Event Dead Zone (EDZ): The minimum distance required to distinguish between two consecutive reflective events.

Attenuation Dead Zone (ADZ): The minimum distance required after a reflective event for the OTDR to accurately measure the continuous loss (attenuation) of the fiber.

Tip: If the dead zone is too long, fiber faults close to the tester (such as a break within the first few meters) might remain hidden. To fix this, you can use a launch fiber (pulse suppressor/dummy fiber) to move the dead zone outside the target fiber under test.

Different wavelengths serve different purposes. It is highly recommended to perform dual-wavelength testing for a comprehensive analysis:

1310 nm: Insensitive to micro-bending within the fiber, but has a higher attenuation rate. It is ideal for pinpointing fiber breaks or localized defects.

1550 nm: Low attenuation, making it perfect for long-distance testing. Crucially, it is highly sensitive to bending (micro-bends/macro-bends).

1625 nm / 1650 nm: Typically equipped with an in-line filter, these wavelengths are dedicated to live fiber testing. They allow you to troubleshoot an active link without disrupting live network traffic.

No, optical fiber cannot amplify signals passively. This "gainer" phenomenon is a optical illusion that typically occurs when two fibers with different backscatter coefficients are spliced together.
When light travels from a fiber with lower backscatter to one with higher backscatter (due to differences in manufacturer or Mode Field Diameter [MFD]), more photons are reflected back to the OTDR. The instrument interprets this surge in energy as a gain.

Solution: You must perform a bi-directional test (measure from End A to End B, and then from End B to End A) and calculate the average value of the two readings to determine the true splice loss.

Pulse width dictates the duration of the light pulse injected into the fiber. It requires a trade-off between reach (dynamic range) and detail (resolution):
Short Pulse Widths (e.g., 3 ns, 10 ns, 30 ns): Inject less energy, limiting the distance, but offer extremely high resolution and small dead zones. Ideal for short-distance, high-connector environments like LANs or FTTH drop sections.
Long Pulse Widths (e.g., 1 µs, 10 µs, 20 µs): Inject massive energy to penetrate long distances, but suffer from low resolution and massive dead zones. Ideal for long-haul backbone testing spanning dozens or hundreds of kilometers.
Rule of Thumb: Always use the shortest pulse width possible that still allows you to clearly see the end of the fiber.

This is a very common and normal discrepancy caused by two main factors:
1. Helix Factor (Take-up Factor): To prevent the delicate glass fibers from breaking when the cable is pulled or bent, they are not laid perfectly straight inside the buffer tubes; instead, they are spiraled around a central strength member. Consequently, the actual physical fiber length measured by the OTDR is typically 0.5% to 2% longer than the physical cable jacket.
2. Index of Refraction (IOR) Settings: An OTDR calculates distance based on the time it takes for light to travel out and back (). If the IOR configured in your tester does not exactly match the manufacturer's actual fiber specifications, the calculated distance will be slightly off.
