Part Number: FTOFSM-G657A1-X
G.657.A1 EasyBand® Bending Insensitive Single-mode Fiber 50.4km Length in Spool
EasyBand® bending insensitive single-mode fiber encompasses all the features of FullBand® fiber and provides good resistance to maro-bending. It has low macro-bending sensitivity and low water-peak level. It is comprehensively optimized for use in O-E-S-C-L band (1260 -1625 nm). It offers good resistance to additional losses due to low macro-bending in the 1625 nm wavelength region. This not only supports L-band applications but also allows for easy installation without excessive care when storing the fiber, for example, in splicing cassettes. For cable use inside buildings, the fiber supports installation with small cable bending radii and compact organizers.
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
EasyBand® bending insensitive single mode fiber 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 fiber 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
