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
