For Submarine Systems Transmitting at 100 Gb/s and Beyond

Terra Wave Ocean 110 Optical Fiber

Product Description

A breakthrough in ocean fiber technology, TeraWave SCUBA Fibers offers a combination of large effective area, excellent cabling performance in the C- and L-bands, and worldclass attenuation. These features enable reliable coherent transmission at 100 Gb/s and beyond over trans-oceanic distances at the highest channel counts. The fiber has a large effective area (110 µm 2 ) that reduces nonlinearities, enabling the launch of higher signal power into the span, and ultra-low attenuation that reduces signal loss.

The pure Silica Core and Ultra Big Area features of the TeraWave SCUBA fiber deliver significant margin beyond that needed for transmitting 100 Gb/s over trans-Atlantic distances. The additional margin can be used to upgrade to denser signal constellations for increased spectral efficiency as new transponders become commercially available. TeraWave SCUBA Fiber is manufactured using OFS’ proprietary manufacturing process, which produces ultra-low polarization mode dispersion (PMD) and exceptional resistance to mechanical stress.
