It is suitable for installation, maintenance and troubleshooting of single-mode and multimode fiber networks.

## Long description

The Lange Łukaszuk CS-R3-40H is an Optical Time Domain Reflectometer (OTDR) intended for testing and characterizing fiber optic links. It performs reflectometry measurements to detect faults, splices and connectors, and to measure attenuation and distance along single-mode and multimode fiber cables. The CS-R3-40H is designed for use in installation, maintenance and troubleshooting workflows where accurate location of events and loss measurements are required.
Advantages
The CS-R3-40H provides precise distance and loss measurements with a user interface tailored for field use. Its measurement capabilities enable technicians to quickly identify the location of breaks, high-loss splices and connector problems. The instrument supports both single-mode and multimode testing, reducing the need for multiple devices on-site. Rugged construction and straightforward controls help maintain consistent results during installation and maintenance tasks.
Suitable for
Installation and certification of fiber optic links
Routine maintenance and link health verification
Locating and diagnosing breaks, bends or high-loss splices
Troubleshooting connector and splice quality in both single-mode and multimode networks
Key specifications
Measurement type: Optical time-domain reflectometry for detecting events and measuring backscatter
Fiber compatibility: Single-mode and multimode fibers
Functions: Fault location, event detection (splices/connectors), attenuation and distance measurement
User interface: Field-oriented controls for on-site operation
Portability: Handheld design suitable for field technicians
How to use
Connect the instrument to the fiber under test using appropriate launch and receive connectors or cables. Configure the measurement parameters suitable for the fiber type and length, then start the OTDR trace to capture backscatter data. Review the trace to identify events, measure distances to faults and quantify attenuation. Save or export results as required for documentation or further analysis. Perform routine calibration and inspection of connectors to ensure consistent measurements.
Usage recommendations
Use a launch (pulse) cable when testing long or live links to accurately locate events near the start of the fiber; verify connector cleanliness before every measurement and select measurement settings appropriate to single-mode or multimode fibers to obtain reliable distance and loss results.
