Brocade Extended Fabrics - license

Brocade Extended Fabrics is a licensed feature for Brocade SAN switches and directors, enabling organizations to leverage the increased availability of DWDM equipment in major metropolitan areas. The most effective configuration for implementing extended-distance SAN fabrics is to deploy Fiber Channel switches at each location in the SAN. Each switch handles local interconnectivity and multiplexes traffic across long-distance DWDM links.
