Single-Mode Fiber offers high power, low loss at 100 Gbps.

Press Release Summary:

Designed for 100 Gbps coherent transport in submarine systems for distances up to 12,000 km, TeraWave™ ULA Ocean Fiber has effective area of 153 µm² that reduces nonlinearities. This enables launch of higher signal power into span as well as low attenuation  (0.176 dB/km at 1,550 nm) that reduces signal loss. Nonlinearity performance and spectral efficiency increase in shorter length applications. Along with LWP performance, fiber offers nominal PMD of 0.02 ps/√km at 1,550 nm.

New Ocean Fiber Offers Industry's Largest Effective Area for Higher Signal Power, Low Loss at 100 Gb/s

TeraWave(TM) ULA Fiber Enables Higher Transmission Speeds with More Wavelengths over Trans-oceanic Distances

PARIS -- OFS, a leading designer, manufacturer and supplier of innovative fiber optic network products, has introduced TeraWave(TM) ULA Ocean Fiber, a new single-mode fiber designed for 100 Gb/s coherent transport in submarine systems for distances up to 12,000 km.

A breakthrough in ocean fiber technology, TeraWave ULA Fiber offers a unique combination of the industry's largest effective area, excellent cabling performance, and significantly reduced attenuation for reliable coherent transmission at 100 Gb/s over trans-oceanic distances. The fiber's very large effective area (153 micron(2)) reduces nonlinearities, enabling the launch of higher signal power into the span, and improves signal loss (0.176 dB/km at 1550 nm).

When used in shorter length applications, the fiber can provide even better nonlinearity performance for increased spectral efficiency.

OFS manufactures TeraWave ULA Fiber using proprietary processes to produce fiber with low water peak (LWP) performance and ultra- low polarization mode dispersion (PMD).

The new fiber is optimized for ultra long haul networks that use advanced modulation formats and coherent detection, such as transoceanic networks where extreme distances between shore end terminals limit the per-channel launch power in DWDM transmission. Compared to earlier generations of submarine fibers, TeraWave ULA Fiber reduces the performance limitations introduced by fiber nonlinearities, thereby supporting higher spectral efficiency and lower repeater spacing.

Applications without repeaters, such as coastal festoons and deep-water crossings, can also take advantage of the large effective area of TeraWave SLA ocean fiber, which permits higher power handling capacity without additional distortion, meaning more channels at higher speeds over longer distances before amplification is required.

As with all its ocean fiber products, OFS has the capability to color and splice TeraWave ULA fibers to meet stringent cable requirements. Fibers are selected to meet customer specifications for number of fibers, colors, lengths, and transmission properties. They are then assembled into sets. Final measurements help ensure that customer specified performance is met for all fibers in the set.
