YOFC G657A2 EasyBand Plus Bending Insensitive Single-mode Fibre Core Bare Optical Fiber
YOFC G657A2 EasyBand Plus Bending Insensitive Single-mode Fibre Core Bare Optical Fiber
1. What is G657A2 fiber ?
- YOFC EasyBand Plus bending insensitive single-mode fibre combines two attractive features: excellent 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).
- The EasyBand® Plus's bending insensitive feature not only guarantees L-band applications but also allows for easy installation without excessive care when storing the fibre especially for FTTH networks application.
- Bending radii in fibre guidance ports can be reduced as well as minimum bend radii in wall and corner mountings.
2. Application:
• All types of fibre cables with different structures
• High performance optical network operating in O-E-S-C-L band
• High speed optical routes for Fibre-to-the-Home networks
• Cables with extreme low bending requirements
• Small-sized fibre cable and optical component
3. Product standards:
- YOFC EasyBand® Plus bending insensitive single mode fibre meets or exceeds the ITU-T Recommendation G.652.D/G.657.A1/G.657.A2/G.657.B2 including the IEC 60793-2-50 type B1.3/B6.a1/B6.a2/B6.b2 Optical Fibre Specification.
4. G657A2 Fiber Characterics:
• Extremely high bending loss resistance in the 7.5 to 15 mm bending radius range
• Full compatibility with all G.652 fibres for any applications
• Low attenuation satisfying the operation demand in O-E-S-C-L band
• Low PMD satisfying high bit-rate and long distance transmission requirements
• Low bending loss for highly demanding cable designs including ribbons
• Accurate geometrical parameters that insure low splicing loss and high splicing efficiency
• High nd-value satisfying long operational lifetime in minimum bend radius
5. Specifications
