Abstract

An optical fibre (100) includes a glass core (102), a trench region (106) and a cladding (108). The optical fibre (100) includes a glass core (102) that may have a core curve parameter α<core> in a range of 6 to 12. The optical fibre (100) includes trench region (106) has a trench curve parameter α<trench> in range of 5 to 8. The optical fibre (100) includes a cladding (108) that has a cladding relative refractive index in range of 0 to 0.05 and a cladding thickness in a range of 42.9 to 47.1 microns. The optical fibre (100) includes a buffer clad region (104) after the glass core (102) and before the trench region (106). The optical fibre (100) has a mode field diameter in range of 8.7 micrometers to 9.7 micrometers at wavelength of 1310 nanometer.
