Description Overview GAOTek fiber optic ranger is applying to FTTx and access network construction and maintenance, to test fiber breakpoint, length, loss and input light automatic detection, automatic test by one key. The tester is compact with a 3.5 in (8.89 cm) colorful LCD screen, new plastic shell design, shock-proof and drop-proof. The tester also combines 8 functions with highly integrated OTDR, Event maps, Stable Light source, Optical power meter, Visual fault locator, cable sequence proofreading, cable length measurement and lighting functions. It could quick detection of breakpoint, universal connector, 600 internal storage, TF card, USB data storage and built-in 4000 mAh lithium battery, USB charging. It is a good choice for long term field work.
