Product standards Fibre complies with or exceeds the ITU-T Recommendation G.652. D
and the IEC 60793-2-50 typeB1.3 Optical Fibre Specification.
Characteristics • Designed for operation over the full optical spectrum from
1260-1625 nm, which provides 50% more usable wavelengths and hence
the transmission capacity is increased • Outstanding optical performance supporting high-speed
transmission technologies such as DWDM and CWDM • Being compatible with existing 1310 nm equipment • Good protection and excellent strip force stability • Accurate geometrical parameters that insure low splicing loss and
high splicing efficiency
