ZTO Plus Bending Insensitive Single-mode Fiber G.657.A2
- Satisfaction guarantee
- Fast delivery
- Quality assurance
Description
ZTO Plus bending insensitive single-mode fibre optic 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 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.
