"Fiber for the Long Haul" ™


TeraWave® Single-Mode Optical Fiber is an optimized large area ITU-T G.654.B fiber designed for terrestrial 400 Gb/s transmission and beyond in the C- and L-bands (1530 nm – 1625 nm) used in long haul systems. It features an effective area 50% greater than G.652.D single-mode fiber to suppress nonlinear effects that limit the reach of G.652.D single-mode fiber. As a result, TeraWave Fiber supports greater distances between regeneration and amplification sites, helping to lower the overall cost of deploying 100 Gb/s and 400 Gb/s coherent systems and increase capabilities for ultra-long haul 10 Gb/s systems..

Product Description

TeraWave® Fiber features a 125 µm2 effective area, very good cabling properties, and low loss to provide superior optical signal-to-noise ratio (OSNR) performance in optical links compared to low loss G.652.D fibers. The fiber takes the best aspects of highly engineered submarine fibers and combines them with cabling and splicing performance that is similar to conventional single-mode terrestrial fiber. These improvements allow system designers to increase distances between amplification and regeneration sites to help reduce overall system costs.

  • An optimized large effective area of 125 µm2 to maximize OSNR for 400 Gb/s and 1 Tb/s transport
  • Low optical loss across the C- and L-bands 1530 nm – 1625 nm to improve power budget
  • Macrobend performance equivalent to conventional G.652.D single-mode fiber to ease installation in terrestrial networks
  • Tight geometric control for low splice loss
  • A patented manufacturing technology that permanently removes the water peak defect for low and stable loss performance in the 1360 nm – 1460 nm E-band for better Raman pump efficiency
  • Long-term attenuation and mechanical reliability from the use of high purity synthetic silica in the entire fiber - both the core and cladding
  • Ultra-low fiber PMD to support non-coherent transmission systems

TeraWave® Fiber provides outstanding cable performance and design freedom for terrestrial long haul systems:

  • 100 Gb/s, 400 Gb/s, and 1 Tb/s using coherent modulation formats
  • Ultra-long haul 10 Gb/s and 100 Gb/s
  • Terabit super-channels
  • Dense wave-division multiplexing
  • Optically-routed mesh networks
  • Long unrepeatered spans such as those encountered in remote regions
