Handheld OTDR
GAO3620

Description - Fiber Optics Instrument - Handheld OTDR (GAO3620)

The Optical Device - Handheld OTDR GAO3620 is a new high tech instrument developed and released to the public this year. It has the ability to show the length, attenuation coefficient, connection point, fault point and loss distribution curves of the fiber, as well as loss between two points, splice loss, and return loss. Even though it has multiple functions and features, the GAO3620 is small in size, its easy to use, and its designed to be durable even for outdoor operations. It is now widely used in loss characteristics analysis and fault point searching in fiber manufacture, installation and maintenance. The Handheld OTDR is compatible with CATV, ISP and Telecommunications Fiber Networks.
