YOFC G657A1 EasyBand Bending Insensitive SM Fibre Core Bare Optical Fiber Spool For Optical Cable

YOFC G657A1 EasyBand Bending Insensitive SM Fibre Core Bare Optical Fiber Spool For Optical Cable

1. What is G657A1 fiber ?

YOFC EasyBand® bending insensitive single-mode fibre encompasses all the features of FullBand® fibre 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 fibre, for example, in splicing cassettes.
For cable use inside buildings, the fibre supports installation with small cable bending radii and compact organizers.

2. Application:

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

3. Product standards:

YOFC EasyBand® 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.

4. G657A2 Fiber Characterics:

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
