Description
Novker NK5100 OTDR (optical time domain reflectometer)
-
he NK5100 is a mini / portable OTDR device intended for fiber-optic testing (especially for FTTH, line maintenance, fault locating).
-
It combines functions such as OTDR, event mapping, light source, visual fault locator (VFL), red laser, and flash light in one unit.
-
It features a 5-inch touch screen interface with multi-touch support.
Key Specifications & Performance Metrics
Here are the more technical parameters reported:
| Parameter | Value / Range |
|---|---|
| Wavelengths supported | 1310 nm & 1550 nm ± 20 nm (for OTDR) |
| Maximum test / measurement range | Up to 100 km |
| Event Dead Zone | ~ 1.5 |
| Attenuation Dead Zone | ~ 6 m |
| Pulse widths available | 5 ns, 10 ns, 20 ns, 30 ns, 50 ns, 80 ns, 160 ns, 320 ns, 500 ns |
| Battery life / operation | > 8 hours (on battery) |
| Fiber type | G.652 single-mode fiber (typical) |
| Physical / usability features | Compact form factor, touch interface, multi functions (OTDR, VFL, etc.) |
Strengths & Limitations / Things to Note
Strengths:
-
The compact size and portability make it suitable for field work, repairs, and installation tasks.
-
Combining multiple fiber test tools in one device (OTDR + VFL etc.) can reduce equipment burden.
-
Decent dynamic range for many typical fiber links (though in many serious applications, higher spec OTDRs are used).

Limitations / Caution:
-
The “dead zones” (especially event dead zone, attenuation dead zone) limit how close two events (splice, fault, connector) can be and still be resolved separately.
-
The 100 km maximum is good, but for very long-haul or ultra-high performance fibers, a more premium OTDR might be required.
-
The data I found is from manufacturer / supplier listings; the real field performance (noise floor, resolution, calibration, drift) might differ.
-
Ensure calibration, connector quality, test settings are appropriate when using.
