Optical Reflectometer OTDR Słowik NK2800S - fiber test instrument

OTDR (optical time-domain reflectometer) Słowik NK2800S is a portable optical reflectometer designed for testing and characterizing fiber-optic links. The instrument performs distance and loss measurements, locates splices and breaks, and evaluates fiber attenuation for both single-mode and multimode fibers. Compact and battery-powered, the NK2800S is intended for installation, maintenance and troubleshooting tasks in telecommunications networks and data center cabling.

Advantages

The Słowik NK2800S provides accurate distance and loss measurement capabilities in a handheld form factor, enabling field technicians to quickly identify faults and measure link performance. Its multi-wavelength support and sensitivity settings allow evaluation of single-mode and multimode fibers, while a clear user interface simplifies reading of events and trace data. Battery operation and rugged construction make the unit suitable for site use where portability and reliable measurements are required.

Suitable for

• Installation and acceptance testing of fiber-optic links
• Maintenance and routine verification in telecommunications networks
• Troubleshooting and locating splices, connectors, and breaks
• Data center fiber verification and link characterization

Key specifications

• Functions: distance measurement, loss measurement, event location (splices, connectors, breaks), attenuation evaluation
• Fiber types supported: single-mode and multimode
• Portable, battery-powered handheld design for field use
• User interface: graphical trace display for viewing events and loss
• Multi-wavelength testing capability and adjustable sensitivity (depending on configuration)

How to use

Connect the OTDR to the fiber under test using the appropriate connectors or adaptors, select the fiber type and test parameters (wavelength, range, and pulse width), and start the measurement. Observe the displayed trace to identify events such as splices, connectors, or breaks and read distance and loss values for each event. Save or export trace data according to on-board options for documentation and further analysis. Ensure optical connectors are clean before testing to avoid misleading reflections.

Usage recommendations

For reliable results, verify connector cleanliness and use appropriate launch and receive cables when testing long links to avoid dead zones. Select the test wavelength and pulse width suitable for the fiber type and span length, and allow the battery to be charged before extended field use. Regularly calibrate and service the instrument as recommended by the manufacturer.
