For positioning the fiber breakpoints and measuring the fiber length Features:    OL-H01 series fiber breakpoint detectors apply the advanced optical time domain reflectometry technology for positioning the fiber breakpoints and measuring the fiber length. It is designed with portable appearance, easy operation and self-contained functions, and widely applicable for fiber construction and maintenance, fiber communication, monitor, fiber CATV system, fiber routing, and fault detection in fiber network.    The facade pattern design corresponds to the human system engineering requirement, endurable and with nice looking. All pushbuttons apply the up-to-date thin film switches, simple and reliable, which are applicable for different service conditions. It is designed with portable appearance. The functions include: indication of up to five faults, figure indication of five digits, automatic shutdown in 3 minutes, and battery low alarm. It is the most practical breakpoint detector of the highest performance/price by far.
