This Recommendation describes the geometrical, transmissible, mechanical, and environment attributes of a super high capacity single-mode optical fibre (CL fibre) which is suitable for C+L band wavelength division multiplexing (WDM) communication system, which can effectively improve the available spectrum bandwidth to meet the demand of high speed and large capacity optical transmission.
According to the division of optical bands by ITU-T G.Sup39, the traditional C-band is 1530-1565nm, the L-band is 1565-1625nm, and the C+L band is 1530nm to 1625nm. However, the C+L band referred to in this Recommendation is 1520nm to 1625nm.
