Abstract
An optical fiber cable including a slotted core (3) having a suitable number of slots (7) and identification members (25) disposed in a designated slot (7B) of the slots (7) for identifying cable information.
Claims37
An optical fiber cable comprising:
- a slotted core comprising a plurality of slots;
- and
- an identification member disposed in a designated one of the plurality of slots for identifying cable information.
A method of manufacturing an optical fiber cable, comprising:
- preparing a slotted core with a plurality of slots having continuous and smooth loci over the entire slotted core length;
- detecting an angular position of a designated one of the plurality of slots at various axial positions of the optical fiber cable;
- and
- feeding a first identification member into the designated slot at a first axial position when the detected angular position matches a predetermined value.
