Optical Fiber Microcable with Multilayer Protective Sheath

摘要

Disclosed is a central loose tube fiber optic microcable that includes a protective sheath enclosing a plurality of optical fibers. The microcable protective sheath is composed of two layers of different synthetic materials, namely an inner layer having an elasticity modulus of about 1500-3000 MPa and an outer layer having an elasticity modulus of about 600-1200 MPa.
