Abstract

An optical fibre includes a glass core, a glass cladding, a primary coating layer and a secondary coating layer. The glass cladding surrounds the glass core. The glass cladding has a cladding refractive index. The primary coating layer is sandwiched between the glass cladding and the secondary coating layer. The primary coating layer may have one of a primary in-situ modulus in the range of 0.1 to 0.2 mega pascal and a primary coating thickness in the range of 2.5 micrometers to 10 micrometers. The secondary coating layer may have one or more of the secondary in-situ modulus greater than or equal to 1.2 giga pascal and the secondary coating thickness in a range of 2.5 to 17.5 micrometers.
