Proximion Launches DCM for ULH Coherent Links

DCM-HDC enables significantly extended reach for 40G/100G coherent links while also reducing power consumption and latency.


Kista, Sweden, Proximion AB, a world-class provider of Fiber Bragg Grating (FBG) based products, today announced the launch of the DCM-HDC, the latest addition to its continuous band dispersion compensation product line. The DCM-HDC is a high-end passive dispersion compensator with extraordinary optical performance. It is targeted for use in Ultra Long-Haul (ULH) coherent detection links.

By compensating large amount of dispersion, up to 10,000 ps/nm per module, at extremely low loss, the DCM-HDC significantly extends the reach of long haul high speed transmission systems. Additional benefits of handling the bulk dispersion outside the DSP, besides reducing the complexity, includes substantially lower power consumption and reduced latency.

We are proud to introduce the DCM-HDC that will be installed already in Q2 this year in a number of state-of-the-art 100G coherent links. The DCM-HDC is the clear market leader with very low losses, less than 3.5 dB per module, thus allowing 150,000 ps/nm compensation with less than 55 dB of loss in a flexi-grid band.
— Martin Åberg, CEO

Proximion will showcase the DCM-HDC at this year’s OFC/NFOEC conference in Anaheim, March 19-21, in booth #3712.
