OFS introduced a new single-mode fiber designed for 100 Gbps coherent transport in submarine systems for distances up to 12,000 km.
The new TeraWave ULA Ocean Fiber boasts the industry’s largest effective area, excellent cabling performance, and significantly reduced attenuation for reliable coherent transmission at 100 Gbps over trans-oceanic distances. OFS said its fiber’s very large effective area (153 µm2) 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 said 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.
