The LA OTDR module features fast acquisition time, good resolution, and up to 35 dB dynamic range for installing and maintaining fiber links. Its integrated light source, accessible through the OTDR port, enables quick fiber identification without switching ports. The integrated power meter adds loss-testing capabilities. The LA module’s optical performance, combined with comprehensive T-BERD/MTS platform features, ensures testing is done right, the first time.
Standard Test Features Include:
- Automatic macrobend detection
- Summary results table with pass/fail analysis
- Bidirectional OTDR analysis
- FastReport onboard report generation
Important Mainframe Details |
These OTDR Modules are generally bundled with a handheld mainframe. Ready to be used as a unit to shoot fiber optic cables and to test link loss at the job site.
For full information on mainframe capability, check the configuration to see which mainframe is bundled. Then, check our page on Viavi OTDR mainframes for full descriptions and datasheets.
