Reinforced structure for a cable or duct with high compression resistance

A cable, comprising:

• an outer jacket;
• a reinforcing core extending longitudinally in said outer jacket and including a plurality of Y-shape ribs extending radially for defining a plurality of chambers;
• and
• at least one optical fiber disposed within each of said chambers, wherein each of said Y-shaped ribs includes a base leg and a pair of legs which define a recess therebetween and which directly connect to said outer jacket.

A tubular conduit having high compression resistance, comprising:

• an outer jacket;
• and
• a compression resistant member disposed longitudinally in said outer jacket, said compression resistant member including a plurality of Y-shaped ribs defining chambers therebetween for respectively receiving information transmission members therein;
• and
• a central strength member extending along the center portion of said compression resistant member;
• wherein said central strength member is made of metal and said compression resistant member is made of plastic.
