Press Release Summary: Handle OTDR DS3620 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 DS3620 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. Handle OTDR is compatible with CATV, ISP
and Telecommunications Fiber Networks.
