Product information

Description

Extralink SUR190-s is an OTDR fiber fault locator that operates at 1310 nm and 1550 nm wavelengths, designed for testing single-mode fiber links. The device detects breaks, splices and connectors, measures event locations and loss, and provides distance information to faults. Its portable form factor and targeted wavelength range make it suitable for installation, maintenance and troubleshooting tasks in telecom and data network fibers.

Advantages

The SUR190-s provides clear identification of reflections and attenuation along single-mode fibers at both 1310 nm and 1550 nm, enabling precise fault localization. The instrument’s portability and simple operation allow technicians to perform on-site tests quickly. Measured distance and loss values assist in evaluating link quality and documenting repair needs. The dual-wavelength functionality supports common field diagnostics for long-haul and access fibers.

Suitable for

  • Locating breaks and macrobends in single-mode fiber links
  • Verifying splice and connector loss during installation
  • Troubleshooting signal attenuation on telecom and data network fibers
  • Maintenance checks and periodic fiber link verification

Key specifications

  • Operating wavelengths: 1310 nm and 1550 nm for single-mode fiber testing
  • Functions: fault location, event detection, distance measurement and loss measurement
  • Portable, handheld form factor for field use
  • Suitable for installation, maintenance and troubleshooting workflows

How to use

Connect the SUR190-s to the fiber under test using the appropriate interface and ensure proper connector cleanliness before testing. Select the desired test wavelength (1310 nm or 1550 nm) according to fiber type and the distance range to inspect. Initiate a scan to generate an OTDR trace that shows events, reflections and attenuation points; read distance and loss information from the trace output. Interpret the trace to locate breaks, high-loss splices or faulty connectors and record measurements for documentation.

Usage recommendations

For reliable results, clean connectors before each measurement, allow the instrument to stabilise after powering on, and choose the wavelength that best matches the fiber span and expected fault characteristics. Use the device in combination with visual inspection tools and power meters when full link verification is required.

Product comparison

This comparison examines the optical time-domain reflectometer OTDR fiber fault locator Extralink SUR190-s with 1310 nm and 1550 nm wavelengths alongside entirely different categories of measuring and installation tools from the same brand: the laser level tripod Tripod stand for laser level Extralink 43–118 cm height adjustable, laser distance meters Extralink EX.25241 Laser Distance Meter 60m and Extralink EX.25258 Laser Distance Meter 40m, cross line laser level Cross line laser level Extralink EX.24671 with self-leveling and 360° rotation, and measuring tape Measuring Tape Extralink HELIOS 1100–1500 mm (tape length range). The fundamental difference lies in their purpose: the main product is designed specifically for testing fiber optic links and locating faults, whereas the alternative devices are built for surveying, indoor layout, distance measurement, and general construction tasks.
