Why Water-Blocking Materials Are Critical in Outdoor Fiber Optic Cables

For outdoor fiber optic cables such as GYTS, GYTA, GYXTW, ADSS, and OPGW, water is one of the biggest threats to long-term performance.
If moisture enters the cable, it can cause micro-bending, attenuation increase, and eventually complete network failure.

This is why high-quality water-blocking materials are essential in outdoor cable manufacturing.

Today we break down the science behind it.
