Product Description

Applications

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

Product Standards

Optical Fiber and Cable 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.

Characteristics

Low attenuation satisfying the operation demand in O-E-S-C-L band
Good bending loss resistance at short radius bends
Low bending loss for highly demanding cable designs including ribbons
Low PMD satisfying high bit-rate and long distance transmission requirements
Accurate geometrical parameters that insure low splicing loss and high splicing efficiency
Standard length: 2,000m; other lengths are also available
