30 Million Kilometers and Growing
In a world where speed is imperative, fiber is the pipeline to connectivity.
Introduced in 1998, our LEAF® optical fiber has become the go-to solution for long-haul and metro networks. In little more than two decades, we have sold more than 30 million kilometers around the globe and deployed it in more than 100 carrier networks.
The information highway, fueled by fiber, allows you to download movies and more in seconds. The first fiber for effective transmission and low dispersion, LEAF provides consistent bandwidth and high transmission of data at lightning-fast speeds.
The industry leader in polarization mode dispersion specifications and boasting the lowest attenuation, Leaf can help existing networks evolve from 10G to the 40G and 100G systems of the future. When paired with legacy networks, LEAF syncs with less equipment which extends cost-savings to the network and ultimately the consumer.
LEAF is a flexible, quality fiber that can be used in multiple network architectures, built to withstand decades of demands in challenging environments.
In the race to satisfy the global demand for bandwidth, LEAF optical fiber is the clear winner as the world's most widely deployed non-zero dispersion-shifted fiber.

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.
Next-Generation Network To Be Deployed in South Africa
FibreCo Telecommunications, a South African open-access network provider, will deploy Corning® optical fiber in its new ultra-high-speed, long-distance fiber optic network in South Africa.
Increased 100G Efficiency for Metro Networks To Be Showcased
ADVA Optical Networking and Corning will demonstrate a 100G solution for the metro environment at the Optical Fiber Communication/National Fiber Optic Engineers Conference in Los Angeles. This demonstration will profile the lowest cost-per-bit 100G transmission available over a distance of 125 km without inline amplification or passive dispersion compensation.
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.
