Corning Endcap Leaf Black 300x293Corning upgraded its LEAF non-zero dispersion-shifted fiber (NZ-DSF) optical fiber for long-haul networks by applying low-loss technology, reducing the fiber's attenuation specification to 0.19 dB/km at 1,550 nm. The attenuation improvement is intended to enable LEAF fiber to achieve longer transmission distances and facilitate an upgrade path to higher data rates of 40 and 100 Gbps.

LEAF fiber was introduced in 1998 and is ITU G.655 compliant. It's designed for a large effective area to allow high-power transmission while minimizing nonlinear impairments and for low chromatic dispersion and polarization mode dispersion (PMD).
