Applications


⛥ Short pitch cables for special application
⛥ High performance optical network operating in O-E-S-C-L band
⛥ High speed optical routes for Fibre-to-the-Home networks
⛥ High speed optical routes in buildings (FTTx)
⛥ Cables with low bending requirements


Characteristics

1. Low attenuation satisfying the operation demand in O-E-S-C-L band
2. Good bending loss resistance at short radius bends
3. Low bending loss for highly demanding cable designs including ribbons
4. Low PMD satisfying high bit-rate and long distance transmission requirements
5. Accurate geometrical parameters that insure low splicing loss and high splicing efficiency


Standard


GL bending insensitive single mode fibre meets or exceeds the ITU-T Recommendation G.652.D/G.657.A1 including the IEC 60793-2-50 type B1.3/B6.a1 Optical Fibre Specification
