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)
Optical cables with high requirements about bending radius
Single-mode optical fiber G.657.A1 meets or exceeds ITU-T Recommendation G.652.D/G.657.A1, including IEC 60793-2-50 Type B1.3/B6.a1 fiber specifications.
Low attenuation meets the requirements of O-E-S-C-L band operation
Good bending loss resistance at short radius bends
Low bending losses for demanding cable designs including ribbon cables
Low PMD meets high bit-rate and long-distance transmission requirement
Accurate geometrical parameters that insure low splicing loss and high splicing efficiency
