LEAF® Optical Fiber

World’s most widely-deployed non-zero dispersion-shifted fiber

LEAF® Optical Fiber

LEAF® Optical Fiber

LEAF® optical fiber has become the go-to solution for long-haul and metro networks. In the race to satisfy the global demand for bandwidth, LEAF fiber is the clear winner as the world's most widely deployed non-zero dispersion-shifted fiber (NZDSF).

Additionally, LEAF fiber is the industry leader in polarization mode dispersion (PMD) specifications and has the lowest attenuation of any NZDSF on the market.

Built to withstand decades of demands in challenging environments, LEAF fiber can be used in multiple network architectures and can help existing networks evolve from 10G to the 40G and 100G systems of the future.

100G Direct Detection Across Record Distance Achieved

In partnership with ADVA Optical Networking, ADVA 100G Metro solution has been used to successfully transport data over 600km of Corning® LEAF® optical fiber. The demonstration represents the first time that direct-detection 100G technology has been used outside of the metro environment and positions it as a genuine 100G solution for regional networks.

Corning’s LEAF® Optical Fiber Now Available with New Lower-Loss Specification

Corning® LEAF® optical fiber, the world’s first large-effective-area, non-zero dispersion-shifted fiber (NZ-DSF) is now further optimized for long-haul networks by applying Corning’s low-loss technology. Already the lowest-loss NZ-DSF fiber on the market, Corning low-loss technology reduces LEAF fiber’s attenuation specification to 0.19dB/km at 1550nm.
