With bending radius R5mm, TFO XtremeBend Plus® fibre provides excellent macrobending performance
and optical performance, this makes it easier for the network designers and operators to deal with much
more challenging installations and environments, widely used in the applications where ultra low bending-loss
at small bending radius are needed, such as FTTH, enterprise network, etc.
TFO XtremeBend Plus® fibre exceeds the ITU-T Recommendation G.657.B3 and IEC 60793-2-50 type B6.b3
optical Fiber Specification, and fully compatible with ITU-T G.652.D and IEC 60793-2-50 type B1.3 fibre.
