1. An optical fibre comprising:
a glass core;
a glass cladding that surrounds the glass core has a cladding refractive index; and
a coating over the glass cladding, wherein the coating has a coating refractive index, wherein absolute difference between the cladding refractive index and the coating refractive index is greater than 0.01, wherein the coating includes:
a primary coating layer that surrounds the glass cladding; and
a secondary coating layer that surrounds the primary coating layer, wherein the secondary coating layer has a secondary in-situ modulus greater than or equal to 1.2 giga pascal, wherein the optical fibre has a diameter of 160 to 180 micrometers, wherein the secondary coating layer has a secondary coating thickness in a range of 2.5 to 17.5 micrometers,
wherein the optical fibre has a zero dispersion slope of up to 0.092 picosecond/(nanometer2.kilometer).
