Optical Time Domain Reflectometer (OTDR) INNE NK2800S — singlemode/multimode fiber testing, event analysis, loss and distance measurement

INNE NK2800S is an Optical Time Domain Reflectometer (OTDR) designed for testing singlemode and multimode fiber optic links. It performs precise distance and loss measurements, detects and analyses events such as splices, connectors and breaks, and produces trace reports that help with troubleshooting, certification and quality control of fiber networks. The instrument supports common measurement ranges and configurations used in telecom and data center installations, offering a compact solution for field technicians and maintenance teams.

Advantages

The OTDR provides clear event analysis and accurate loss and distance measurement for both singlemode and multimode fibers. Its measurement reports are suitable for fault location and documentation during installation and maintenance. The device is engineered for field use with a user-oriented interface that streamlines setup and reduces measurement time while maintaining reliable results across typical fibre network scenarios.

Suitable for

• Installation and certification of fiber optic links in telecom and data networks
• Routine maintenance and performance verification of singlemode and multimode fibers
• Fault location and splice/connector testing in point-to-point and passive optical networks

When it may not be suitable

The NK2800S is intended for standard field testing and troubleshooting; it may not be suitable for highly specialized laboratory measurements that require ultra-high dynamic range or custom wavelength combinations beyond the device’s supported test settings. It is also not a replacement for systems that require integrated network layer testing or active traffic analysis.

Key specifications

• Supported fiber types: singlemode and multimode
• Functions: distance measurement, event detection and analysis, loss measurement, trace report generation
• Typical use environment: field installation, maintenance and fault location for telecom and data networks
• Output: measurement traces and exportable reports for documentation and certification

How to use

Connect the OTDR to the fiber under test using the appropriate launch and receive connectors, select the fiber type and measurement range, and start the trace acquisition. Review the displayed event map and loss/distance readings, adjust measurement parameters if necessary, and save the trace for later analysis or export. Use a launch cable or optical loopback where required to characterise near-end events and ensure accurate end-to-end loss results.

What to consider before purchase

• Confirm required fiber types and wavelengths are supported for your applications
• Consider the required dynamic range and maximum test distance for your longest links
• Check compatibility with connector types and whether launch/receive cables are included or needed
• Decide if integrated reporting formats and export options meet your documentation workflow

Usage recommendations

For reliable results, perform measurements with clean connectors and appropriate launch/receive cables, set the instrument to the correct fiber type and range before each test, and save raw traces for later review. Regularly verify calibration and use event threshold settings that match your network’s loss criteria to improve fault detection and documentation consistency.
