Corning Introduces Ultra-Low-Loss, Single-Mode Optical Fiber

Corning unveiled a single-mode optical fiber with low attenuation and low polarization mode dispersion (PMD) characteristics, enabling greater system reach and longer span lengths in long-haul and regional terrestrial networks.



Corning said its new fiber, which compatible with the installed base of single-mode fibers, has the lowest loss of any terrestrial-grade fiber with maximum attenuation available between 0.17 and 0.18 dB/km at 1550 nm. Additionally, the fiber has the lowest PMD of any ITU-T G.652 compliant optical fiber featuring a ≤ 0.04 ps/√km PMDQ link design specification. Combined, these features provide spare network margin that can be leveraged to extend network span lengths, skip amplification sites, upgrade to faster bit rates, add network components for improved flexibility or lengthen the distance between regenerators.
