GL FIBER provides the whole series of SMF products that meet and even excel the requirements of standards on performance indicators. Due to the high stability, these products effectively meet the demand for high speed, large capacity, long distance and small bending radius necessary for signal transmission in different applications.
Our bending insensitive single-mode fibre encompasses all the features of GL FIBER® 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.
Type:
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.
Standard:
The fiber complie with or exceed the technical specifications in ITU-T G.657.D /A1.
Feature:
1. Low attenuation satisfying the operation demand in O-E-S-C-L band
2. Good bending loss resistance at short radius bends
3. Low bending loss for highly demanding cable designs including ribbons
4. Low PMD satisfying high bit-rate and long distance transmission requirements
5. Accurate geometrical parameters that insure low splicing loss and high splicing efficiency
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
