OFS introduced a new fiber for use in submarine cables engineered for long and medium haul ocean repeatered systems utilizing advanced modulation formats, e.g., RZ-DPSK, in dense wave division multiplexing (DWDM) systems.
The new TrueWave HD ocean fiber offers a large negative dispersion value of -14 ps/nm-km, taking advantage of the fact that newer modulation formats allow for larger values of accumulated dispersion without deleterious non-linear effects.
Non-linearity performance and lower span loss is optimized when the fiber is used in combination with the large positive dispersion and large effective area of a non dispersion-shifted fiber (such as OFS’ AllWave ZWP Ocean Fiber or UltraWave SLA Ocean Fiber). In this configuration, TrueWave HD fiber can provide superior performance in a cost effective solution that is second only to slope-matched systems.
