In the race to satisfy the global demand for bandwidth, Corning® LEAF® optical fiber is the clear winner as the world's most widely deployed non-zero dispersion shifted fiber (NZ-DSF). Optimized for long-haul and metro networks, LEAF fiber is a technically advanced product that provides high capacity, broad system flexibility, and superior performance. Additionally, LEAF fiber is the industry leader in polarization mode dispersion (PMD) specifications and has the lowest attenuation of any NZ-DSF on the market today, enabling networks to evolve from the current 10G to the 40G and 100G systems of the future.
