Each PBT loose tube typically holds up to 12 fibers, with the number of tubes (plus fillers) determining total cores. This model contains 144 individual optical fibers housed in loose tubes, providing exceptional bandwidth, low attenuation, and strong mechanical performance in harsh environments. Each fiber is protected within PBT loose tubes filled with water‑blocking gel, stranded around a central strength. Fiber cores are the heart of fiber optic cables, transmitting light signals that carry data. Test for vertical flame.
