摘要：
The present disclosure provides an optical fiber. The optical fiber includes a core. The core has high compressive stress. The compressive stress of the core is in a range of about 20 to 60 MPa. The optical fiber includes a cladding. The cladding is divided into a first cladding layer and a second cladding layer. The second cladding layer has a high residual stress. The high residual stress of the second cladding layer is in a range of about 20 to 60 MPa. The optical fiber enables reduction of particle related breaks. Further, the optical fiber has elevated LLT strength. The LLT strength is about 6 Kg. The optical fiber has high proof test yield. Furthermore, the optical fiber is highly sensitive to micro-bending of the optical fiber.
