Optical cable cutting device capable of measuring cutting length
Technical Field
The invention relates to the technical field of optical cable cutting equipment, in particular to an optical cable cutting device capable of measuring cutting length.
Background
Fiber optic cables are manufactured to meet optical, mechanical, or environmental performance specifications and utilize one or more optical fibers disposed in a surrounding jacket as a transmission medium and are telecommunication cable assemblies that may be used individually or in groups. The optical cable is mainly composed of optical fibers (thin glass filaments like hair), a plastic protective sleeve and a plastic sheath, and metals such as gold, silver, copper and aluminum are not contained in the optical cable, so that the optical cable generally has no recycling value. The optical cable is a communication line which is formed by a certain number of optical fibers according to a certain mode to form a cable core, is coated with a sheath, and is also coated with an outer protective layer for realizing optical signal transmission.
