Abstract
Official abstract text for this publication.
A slot type optical cable includes: an optical fiber; a slot rod that includes a plurality of ribs forming a groove in which the optical fiber is accommodatable; and a cable jacket that is provided around the slot rod. The cable jacket includes a sheath portion that is formed around the slot rod at substantially the same thickness by linearly connecting outermost peripheral edges of adjacent ribs.
First claim
Opening claim text (preview).
The invention claimed is: 1. A slot type optical cable comprising: an optical fiber; a slot rod that includes a plurality of ribs forming a groove in which the optical fiber is accommodatable; and a cable jacket that is provided around the slot rod, wherein the cable jacket includes a sheath portion that is formed around the slot rod at substantially the same thickness, the sheath portion linearly connects outermost peripheral edges of adjacent ribs, the sheath portion linearly connects outermost peripheral edges of a same rib, and the number of the ribs is 6 to 8. 2. The slot type optical cable according to claim 1 , wherein a density of a material used for the sheath portion is lower than 0.942 g/cm 3 . 3. The slot type optical cable according to claim 1 , wherein a ribbon in which the optical fiber is arranged is accommodated in the groove, and the ribbon is an intermittent ribbon in which a connection portion and a non-connection portion are intermittently formed in a longitudinal direction between some or all of adjacent optical fibers.
