TeraXion’s static dispersion ClearSpectrum™ product suite features the DCMX, a passive dispersion compensation module which is available in several form factors including LGX. With its low insertion loss compared to DCF, the DCMX allows system vendors to save on amplification cost for in-line applications. Moreover, the small footprint and extended reach - up to 400 km - of this compensator make it suitable for long point-to-point spans or hut skipping configurations.
TeraXion also proposes the DCX, which is the athermal FBG package designed for customers who wish to incorporate dispersion compensation onto their transponder board or amplifier module. Both the DCX and the DCMX are tailored to compensate for different fiber types such as NDSF, DSF and NZDSF. In their positive dispersion versions, the fixed compensators are used to emulate chromatic dispersion in a T&M environment.
