¿µ¹®³»¿ë¿ä¾à Category A fibres are optimized for reduced macrobending loss compared to ITU-T G.652.D fibres and can be deployed throughout the access network. These fibres are suitable for use in the O-, E-, S-, C- and L-band (i.e., throughout the 1 260 nm to 1 625 nm range). The fibres and requirements in this category are a subset of ITU-T G.652.D and are therefore compliant with ITU-T G.652.D fibres and have the same transmission and interconnection properties. Category B fibres are optimized for further reduced macrobending loss and therefore are capable of being used at very low values of bend radius. These fibres are intended for short reach distances (less than 1 000 m) at the end of the access networks, in particular inside buildings or near buildings (e.g., outside building riser cabling). The application length of ITU-T G.657.B fibre depends on the deployment strategy of each network operator. Category B fibres are not necessarily compliant with ITU-T G.652.D]in terms of chromatic dispersion coefficient and polarization mode dispersion (PMD) specifications.
