Corning Incorporated has sold more than 30 million kilometres of LEAF optical fibre since introducing the product in 1998, making LEAF fibre the most widely deployed non-zero dispersion-shifted fibre in the world.
"LEAF fibre is a great example of Corning innovation and has been one of Corning's most successful products, meeting customer needs over many years," said Martin J. Curran, senior vice president and general manager, Corning Optical Fibre. "The performance of this fibre is proven by its operation in more than 100 carrier networks worldwide."
Compared to other non-zero dispersion-shifted fibres, LEAF fibre, with its large effective area, allows higher levels of optical power to be transmitted while minimizing nonlinear impairments that can degrade transmission-system performance. This fibre has low chromatic dispersion, which simplifies dispersion compensation and lowers the cost of network installation and operation for long-haul carriers. In addition, this fibre has low-polarization-mode dispersion (PMD), which enables high-data-rate transmission. LEAF fibre continues to be the fibre of choice for new long-haul builds and upgrades to existing builds as it provides longer uncompensated reach, room for future upgrades, and optical specifications that can be leveraged to simplify and lower network costs.
In 1998, Corning demonstrated a 10 Gb/s system using LEAF fibre. This year, at the OFC/NFOEC conference, Corning demonstrated LEAF fibre's performance at 40 Gb/s in a system with Opnext, the industry-leading maker of 40 Gb/s transponders. This demonstrated 40 Gb/s system, as in 1998, uses single-stage, in-line amplifiers and dispersion compensation only at the terminals, showing that LEAF fibre brings the same network simplification and cost advantages it did upon commercial introduction.
Corning LEAF optical fibre is the world's most widely deployed non-zero dispersion shifted fibre. A backbone by LEAF fibre provides network capacity and flexibility enabling future growth and compatibility with emerging network technologies. With its moderate dispersion and large effective area, LEAF fibre continues to be the fibre of choice for today's high-data-rate and tomorrow's all-optical long-haul and metropolitan networks.
