Title: Thick-walled cable sheath having noncircular cavity cross section
Inventor: STEVENS JOHN BOYET
IPC: G02B6/44
Filed: 2000-06-01
Abstract: PROBLEM TO BE SOLVED: To realize the maximum compression strength of an optical fiber cable by giving a cavity having a noncircular cross section and arranging the noncircular cross section in such a way that its short axis forms substantially the same straight line as a line connecting a plurality of strength members extending in the longitudinal direction. SOLUTION: An optical fiber cable 1 has a circular outer peripheral part 2 and a noncircular cavity 3. One or a plurality of optical fibers are inserted into the cavity 3. A strength member 4 extends in the longitudinal direction in the cable 1 in the same direction as the cavity 3. A minor axis X of the cavity 3 in a cross section forms substantially the same straight line as a line connecting the strength members 4. Since the cable 1 is crushed or has low compression strength in the direction parallel with the minor axis X of the cavity 3, the minor axis X forms the same straight line as the line connecting the strength members 4. That is, the cavity 3 having the noncircular cross section is achieved by realizing such optical fiber cable 1 that has the minor axis X forming substantially the same straight line as the line extending between the strength members 4.
