## Long description

The Lange Łukaszuk CS-R5B-50H Optical Reflectometer (OTDR) is a handheld test instrument designed to locate faults, measure event distances and estimate loss in fiber-optic links. Intended for field technicians and laboratory engineers, the CS-R5B-50H supports inspection, certification and troubleshooting of both single-mode and multimode fiber installations. The instrument combines portability with measurement capabilities needed for accurate characterization of fiber networks.
Advantages
The CS-R5B-50H offers precise distance measurement and event identification in a compact, rugged handheld form factor suitable for on-site use. It provides automated analysis functions that reduce manual interpretation time while retaining options for manual review by experienced technicians. The device is compatible with standard single-mode and multimode fibers and is optimized for tasks such as fault location, splice verification and link loss estimation. Its user interface and measurement reports are designed to integrate with common workflow and documentation practices.
Suitable for
 Field testing and troubleshooting of fiber-optic cables
 Laboratory measurements and verification during installation or maintenance
 Locating breaks, connectors, splices and high-loss events in fiber runs

Key specifications
 Form factor: handheld, portable OTDR
 Fiber types supported: single-mode and multimode
 Primary functions: event location, distance measurement, loss estimation
 Usability: automated analysis modes with manual review capability
 Durability: rugged enclosure for field use
How to use
Connect the test port of the OTDR to the fiber under test using appropriate launch and receive cables as required for the test distance and dynamic range. Power on the instrument and select single-mode or multimode mode depending on the fiber type. Choose the appropriate test range and pulse width for the expected link length, then start the measurement. Review the trace to identify backscatter events, reflectance peaks and loss points. Use the device's automated analysis to mark events and calculate distances and losses, and perform manual adjustments if necessary to refine event interpretation.
Usage recommendations
Use a suitable launch (pulse) cable to eliminate dead zone errors near connectors, verify instrument calibration periodically, and store measurement reports using the instrument's reporting functions or by exporting data to external software for documentation and further analysis.
