TeraXion, a manufacturer of value-added optical components, announced its new line of low dispersion 50 GHz and 100 GHz DWDM filters, perfectly suited for transmission speed from 10 to 40 Gb/s.
Fiber Bragg Gratings (FBGs) based filters have been recognized for years for their flat-top response, steep spectral roll-off and excellent adjacent channel isolation. They are intensively used in optical add-drop modules and in DWDM multiplexers and demultiplexers. However, the intrinsic chromatic dispersion of FBGs limited their usage to lower bit rates.
As transmission bit rates and distance increase, dispersion management in optical components becomes increasingly important. TeraXion's new TF-WDM-LD DWDM filters will enable high performance DWDM system deployments as they are designed to minimize group delay variation inside and outside their passband. Minimizing the group delay variation reduces both the level and variation of chromatic dispersion introduced by the filter to the selected channel as well as to the adjacent and non-adjacent express channels. At 40 Gb/s, the total group delay variation must be well below 10 ps.
Samples are presently available for evaluation purposes.
This new product announcement follows TeraXion's launch of its athermalized 25 GHz WDM Filters at OFC 2001.
