EasyBand® Plus G.657.A2 Bending Insensitive Single-Mode Fiber
The EasyBand® Plus Bending Insensitive Single-mode Fibre combines two attractive features: excellent low macro-bending sensitivity and a low water-peak level. It is comprehensively optimized for high-performance optical networks operating in the entire O-E-S-C-L band (1260-1625 nm).
The bending insensitive feature of EasyBand® Plus not only guarantees L-band applications but also allows for easy installation without excessive care when storing the fibre, especially for Fibre-to-the-Home (FTTH) networks applications. Bending radii in fibre guidance ports can be significantly reduced, as well as minimum bend radii in wall and corner mountings. It meets or exceeds the stringent ITU-T Recommendation G.652.D/G.657.A1/G.657.A2/G.657.B2 and the IEC 60793-2-50 type B1.3/B6.a1/B6.a2/B6.b2 Optical Fiber Specifications.
Key Characteristics & Applications
- ✔Extremely high bending loss resistance in the 7.5 to 15mm bending radius range.
- ✔Full compatibility with all G.652 fibres for any applications, with accurate geometrical parameters ensuring low splicing loss.
- ✔Ideal for high-speed optical routes in FTTH networks, extreme low bending requirement cables, and small-sized fibre optical components.
