Tunable and passive chromatic dispersion compensators are mainly deployed at the terminals to precisely compensate dispersion of festoon & submarine direct detection networks. In ultra-long haul submarine networks such as transatlantic and transpacific links, the bulk of chromatic dispersion cannot be fully managed by the DSP. High level dispersion compensators become a necessity for these links in order to compensate substantial amounts of dispersion on 40 & 100 Gb/s links using coherent detection and large effective area fiber such as G.654.

The TFC is a narrowband optical filter offering wavelength tunability over the entire C-band with outstanding channel isolation. These features are perfectly suited for submarine and superchannels transmission applications such as signal tracking, sub-band filtering or noise suppression.

On the laser side, TeraXion's narrow linewidth semiconductor lasers offer unmatched wavelength stability for coherent OTDR and full C-band tunability for submarine coherent communication research.
