Grandway FHO1500 OTDR



Grandway FHO1500 OTDR

OTDR Grandway FHO1500 is an intelligent fiber optic network measuring instrument. It can measure the total length, total loss, return loss and distance between two points of optical fiber and optical cable, and determine the location of connection points, connection points, fault points and break points of optical fiber and optical cables.
