Long-Haul Fiber Networks

Reach and Performance

Long-haul, terrestrial optical fibre networks connect cities and countries throughout the world. Today, these networks typically range from a few hundred to several thousand kilometres, and have largely migrated to 100G-based dense wavelength division multiplexing (DWDM) systems with 80 channels or more.

Corning's innovative line of optical fibres meet all of these requirements for distance, bit rate, and capacity, and they also provide both high speed and low attenuation over long spans. In addition, they are capable of managing the dispersion in legacy, lower bit rate systems that accumulates as light signals travel over long distances as well as the nonlinear penalties that can limit performance for existing systems.

No matter your network architecture, Corning’s high-data-rate fibres address your network needs both today and in the future.

Corning® TXF™ Optical Fibre

Most advanced fibre for long-haul networks

Corning® TXF™ Optical Fibre

Corning® SMF-28® ULL fibre has the lowest loss of any terrestrial grade single-mode fibre with a maximum attenuation of 0.17 dB/km at 1550 nm. SMF-28 ULL fibre has been deployed around the world in some of the most challenging network applications, where ultra-low attenuation can be leveraged to extend network span lengths, skip amplification sites, upgrade to faster bit rates, add network components for improved flexibility, and/or lengthen the distance between regenerators.

Ultra-low-loss optical fibre allows carriers and cloud operators to extend optical reach at very high-data rates and makes networks scalable for higher capacities as the demand for bandwidth continues to...

Corning® SMF-28® Ultra Optical Fibre

Industry-leading attenuation and improved macrobend performance

SMF-28® Ultra optical fibre was the first in the market to combine the benefit of industry-leading attenuation and improved macrobend performance, all in one fibre. This premium single-mode fibre is designed for regional, long-haul, metro, access, mobile, and fibre to the home (FTTH) applications, along with being fully backward compatible with the installed base of legacy single-mode fibres.

Corning® LEAF® Optical Fibre

Most widely deployed non-zero dispersion-shifted fibre

Corning® LEAF® Optical Fibre

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

Additionally, LEAF fibre 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 fibre can be used in multiple network architectures and can help existing networks evolve from 10G to the 40G and 100G systems of the future.
