Overview – Handheld OTDR
This handheld OTDR 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, slice loss and return loss. It is widely used in loss characteristics analysis and fault point location in the manufacture, installation and maintenance of fibers. The portable OTDR is compatible with CATV, ISP and telecommunications fiber networks.
