In the GYTC8Y cable, singlemode/multimode fibers are positioned in the loose tubes, while the loose tubes
strand together around metallic central strength member into a compact and circular cable core, and the water-blocking
materials are distributed into interstices of it. After a PSP/APL is applied around the cable core, this part of cable accompanied
with the stranded wires as the supporting part are completed with a PE sheath to be a figure-8 structure.
