YOFC G.657.A2 EasyBand® Bending Insensitive Single-mode Fibre

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.

Characteristics

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
