Welcome to visit Hirundo Optics Inc website
The Optical Time-Domain Reflectometer (OTDR)series products are high-performance portable OTDRs,characterized by their small size,lightweight,powerful functions,and easy operation.
They can be used to measure fiber optic attenuation, connector loss,
Multi-wavelength measurement mode,capable of analyzing the attenuation status of the same fiber at different wavelengths.
Intelli gent analysis oftestresults,capable of generating testreportsin different formats according to user needs.
Battery life>8 hours,suitable for long-term field operations.
One-click automatic operation for all important tests.
Widely used in engineering construction,line maintenance &testing,
and urgent repairs of fiber optic communication systems;measurement of fiber optic cables in research and production etc.
meeting the construction,installation, troubleshooting,renovation,and maintenance needs of fiber optic cables and fibers in FTTx,
metropolitan area networks, backbone networks,and other optical networks.
