SINGLEMODE OPTICAL FIBRE SMF – PATCHCORD
Step index singlemode optical fibres with improved core and cladding
geometry suitable for its use in patchcord cables.
All technical specifications are subject to change without prior notice. Consult OPTRAL for the latest edition.
These fibres comply with IEC 60793-2-50, UIT G.652.B, G.652.D, Telcordia
GR-20-CORE, ANSI/IECA S-87-640.
