Richardson Networks Solutions Company Launches Handheld Field Test Tool for Fiber Insights

HFR Networks' flexiTester, paired with its smartphone app, streamlines network testing, reducing the need for hazardous high-altitude work and complex equipment handling

Richardson-based HFR Networks Inc. announced the availability of flexiTester, a handheld device driven by a Smartphone app to field test access wavelengths and services.

HFR is a provider of intelligent xHaul RAN Transport and Edge Access solutions.

The company said that when configuring dense wavelength-division multiplexing (DWDM) networks, field engineers must use various pieces of test equipment to validate optical connectivity, a process that is time consuming, cumbersome, and can be dangerous when equipment is located at great heights on top of buildings or towers.

“The flexiTester eliminates common testing challenges while increasing productivity and accelerating deployments,” HFR Networks President Paul Crann said in a statement. “Field engineers can now rely upon one handheld device, the flexiTester, to speed installation and/or troubleshooting – freeing their valuable time to focus on other critical tasks.”

According to UfiSpace, DWDM is an optical transmission technology that uses multiple wavelengths of light to combine several data streams onto a single optical fiber.

The company said that the flexiTester consolidates many pieces of test equipment into one handheld device to simplify the testing process and significantly decrease the testing time while also improving safety.

According to HFR, the flexiTester supports multiple critical functions, including optical power meter, OTDR, Smart Tunable SFP+/SFP28 testing, and Visual Fault Finder functions. Open and standards-compliant for use across third party vendors, the flexiTester supports both semi-active and passive DWDM deployments.

The company said that field engineers can use the flexiTester to pro-actively validate the service path, including the optical connections within the fiber distribution panel.

According to HFR, when used with its flexiHaul Smart Tunable Optics (SFP+/SFP28), flexiTester checks the automatic wavelength self-tuning functions, allows for manual wavelength tuning, and enables control of the optics via the handheld device or through the Smartphone application.
