TeraXion

TeraXion will show a compact tunable dispersion compensator that manages chromatic dispersion simultaneously across the entire C-band at OFC 2017 in Los Angeles on 21–23 March.

The ClearSpectrum TDCMX-SM has been designed to provide significant cost and space savings in 100G interconnects based on direct-detect technology such as PAM4 and DMT. Unlike coherent modules, which compensate for optical dispersion within the digital signal processor, direct-detect optics require separate optical dispersion compensation in the line system.

The indium-phosphide-based, high-bandwidth, dual-polarisation IQ modulator from TeraXion can enable increased spectral efficiency and reach in next-generation, single-carrier transmission systems at speeds beyond 100Gb/s, the company claims.

“Our commercially available indium phosphide modulators are ready to meet system requirements for 100Gb/s and upcoming advanced modulation formats,” stated Ian Woods, vice president of high-speed photonic components at TeraXion.
