APL2+ Long Haul OTDR

APL 2 Plus OTDR is a multi touch screen platform OTDR, feature rich with built in optical light source, optical power meter & visual fault locator, for testing of terrestrial, long distance or datacom optical fiber networks.

APL 2 Plus is available in Single mode, Multimode and PON model variant with the option to customize the OTDR for availability of up to 5 wavelengths (by configuring up to 2 distinct OTDR modules in the same OTDR unit). APL 2 Plus offers 40 dB, 43 dB & 45 dB dynamic range options for long distance terrestrial fiber network testing.
