¿µ¹®³»¿ë¿ä¾à This recommendation is the aim to support this optimization by recommending strongly improved bending performance compared with the existing G.652 single mode fibre and cables. This is done by means of introducing two classes of single mode fibres, one of which, class A, is fully compliant with the G.652 single mode fibres and can also be used in other parts of the network. The other class, class B, is not necessarily compliant with G.652 but is capable of low values of macrobending losses at very low bend radii and is pre-dominantly intended for in-building use.
