Optimized for Reach and Performance in Terrestrial Core Networks

With sustained worldwide bandwidth growth, network operators are driving new investments in long-haul network infrastructure. These terrestrial core networks, connecting cities and countries throughout the world, are vital links to data centers, submarine cable landing stations, and regional hubs.  Both to meet today’s needs and to prepare for tomorrow’s technologies, network operators are looking to advanced optical fibers to enhance and future-proof network investments while driving improvements in cost per bit.

Corning's innovative line of advanced optical fibers drive next-generation design capabilities in reach, bit rate, and capacity through a combination of state-of-the-art capabilities in attenuation and effective area.  These attributes enable network operators to unlock new opportunities in design and performance beyond what is possible with standard terrestrial single-mode fiber.

Product Highlights

Long-Haul Optical Fiber Products

Corning® SMF-28® ULL Optical Fiber Portfolio

Lowest loss of any 80 µm2 terrestrial-grade, single-mode fiber

Corning® SMF-28® ULL Optical Fiber Portfolio

Corning’s SMF-28® ULL optical fiber portfolio has the lowest-loss 80 µm2 terrestrial-grade fibers available in the market – with millions of kilometers sold and deployed worldwide in the harshest environments and most demanding terrestrial core networks.

Compliant to ITU-T G.654.C, this ultra-low-loss fiber 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.

Corning® TXF® Optical Fiber

Low-loss, large effective area terrestrial G.654.E compliant fiber

Corning® TXF® Optical Fiber

The superior attributes of TXF® optical fiber, compliant to ITU-T G.654.E, allow for the provision of an additional network margin that can be leveraged to enable reliable, high-data-rate transmissions over longer spans and extended reach. This allows long-haul networks with TXF fiber to be designed more efficiently, reducing the need for amplification sites, which is particularly important in remote territories with challenging terrains. TXF fiber also minimizes the number of needed regenerators, even as higher data rate upgrades are planned with more stringent OSNR requirements.

Corning® LEAF® Optical Fiber

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

Corning® LEAF® Optical Fiber

Corning® LEAF® optical fiber  is the world’s most widely deployed non-zero dispersion-shifted fiber (NZDSF). Typically deployed in non-coherent long-haul and metro networks, LEAF fiber combines low dispersion and low loss. This ITU-T G.655.D-compliant fiber enables improved performance flexibility and compatibility with emerging network technologies with industry-leading performance.

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