摘要
The fibre includes a ring of intermediate index value surrounding core, within outer sleeve section. Mono-mode optical fibre is intended to operated with light of wavelength 1550 nm and offers a dispersion coefficient between 0.8 and 0.5 ps/nm.km, and a chromatic dispersion which is between 130 ps/nm.km and 90 ps/nm.km. It comprises a core and sleeve whose refractive index profile includes a central core of index greater than that of the sleeve (to r1). This is surrounded by a ring (r2 to r3) having an index which is greater than that of the sleeve but less than that of the core. Regions of lower refractive index (r1 - r2 and r3 to r4) separate the above mentioned sections.
