| Specification | Mini Series (NK2800) | Compact Pro (NK3200/NK4000) | Elite Series (NK6200) |
|---|---|---|---|
| Display | 3.5-inch Color LCD | 3.5″ to 4.3″ Touch Screen | 7-inch Capacitive Touch |
| Dynamic Range | 20 dB | 24 dB – 26 dB | 32 dB – 45 dB |
| Max Measurement Range | Up to 80 km | Up to 100 km | Up to 420 km |
| Event Dead Zone | 2.5 m | 2.5 m – 3 m | 0.5 m – 0.8 m |
| Integrated Functions | 5-in-1 (OTDR, OPM, VFL, LS, Flashlight) | 9 to 12 Functions (Event Map, Ethernet Test) | 9 Modules + Advanced Ethernet Testing |
| Live Fiber Testing | Supported (1550nm) | Supported (F1/F2 Models) | Advanced PON Testing Options |
| Battery Life | > 12 Hours Standby | > 12-20 Hours | High Capacity / Long Duration |
* Technical Note: Dynamic range largely determines the measurable distance. For FTTx/Access networks, the Mini and Compact Pro series are ideal. For Metropolitan and Long-Haul Backbone networks, the NK6200 series is recommended due to its superior dynamic range (up to 45dB) and short dead zones (0.5m). All models support SOR file export.
FAQ for OTDR Testers
Which OTDR model is best for PON / FTTH networks?
For FTTH/PON networks, we recommend models with Live Fiber Testing support (such as the NK4000F1/F2 or NK6200 series). These allow you to test at 1625nm or 1650nm without interrupting the active service signal (1310/1490/1550nm).
Do your OTDRs come with analysis software?
Yes, all our OTDRs include built-in intelligent analysis software to create Event Maps and Pass/Fail assessments. Files are saved in the standard .SOR format, compatible with professional PC reporting software.
What is the difference between dynamic range and dead zone?
Dynamic range (e.g., 32dB vs 45dB) determines how far the OTDR can measure. Dead zone determines the OTDR’s ability to detect closely spaced events. For short links, a short dead zone (like NK6200’s 0.8m) is crucial. for long-haul, high dynamic range is priority.
Does the device support multiple languages?
Yes, the user interface supports English, Spanish, Portuguese, and other major languages to facilitate global deployment.
What is the warranty and calibration policy?
ZTO provides a standard factory warranty (1-3 years depending on model). Each unit is calibrated before shipment, and we offer technical support for the lifetime of the product.
Can I purchase a single OTDR unit for personal use?
As a professional manufacturer focused on industrial and carrier-grade infrastructure, our standard MOQ is 10 units per order. This wholesale model allows us to maintain factory-direct pricing and provide dedicated technical support for large-scale fiber optic projects and global distributors.
Note: We do not offer retail, second-hand sales, or rental services.
