Mr Henry ThaiKocent Optec Limited is our long-term partner. In 8 years of co-operation times we together win many projects. Their fast connector and FTTH drop cable quality are best. Their products are cover my country now.

Mr PabloI was surprised when i made first order with Kocent Optec Limited in 2014. One container 40GP of GYXTW cable and one container 20GP for fast connector, patch cord and adapter. They finished this order in 2 weeks only. Now we also purchase many type of FDB box and Splice Closure Box from them. Hope we will be stronger and stronger in telecom field.

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
