For Submarine Systems Transmitting at 100 Gb/s and Beyond


TeraWave® SCUBA 150 Ocean Optical Fiber is optimally designed to deliver best-in-class performance for coherent transport in submarine systems for distances up to 12,000 km with high spectral efficiency. It is fully compliant with the ITU G.654.D standard for cutoffshifted fiber.

Product Description

A breakthrough in ocean fiber technology, TeraWave SCUBA 150 Fiber offers a combination of the industry’s largest effective area, excellent cabling performance in the C- and L-bands, and world-class 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 ultra large effective area (153 μm2 ) that reduces nonlinearities, enabling the launch of higher signal power into the span, and ultra low attenuation (0.155 dB/km at 1550 nm) 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-Pacific 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.


  • Effective area of 153 μm2
  • Nominal loss of 0.155 dB/km at 1550 nm
  • Enables launch of higher signal power into the span
  • Enable higher transmission speeds with more wavelengths over trans-oceanic distances
  • Reduces amplifier noise in the C- and L-bands
  • Supports polarization-multiplexed, coherent transport using high spectral efficiency modulation formats
  • Proof tested to 200 kpsi to help ensure long-term reliability under extreme conditions
  • Ultra-long haul networks using advanced modulation formats and coherent detection such as transoceanic networks
  • Applications without repeaters, such as coastal festoons and deep-water crossings
