Booming bandwidth demand spawns opportunities for packet processor developers.
 Changes in metropolitan area (metro) networks have led to significant design activity among telecom equipment makers. They are either adapting existing platforms or developing ones that support emerging operator requirements. It also means new opportunities for chip makers.
Using dense wavelength division multiplexing (dwdm) technology to carry traffic over a fibre using multiple optical wavelengths is not new. What has changed is the bandwidth demand due to growth in broadband traffic and video services in particular.
Service providers want networks that can be configured dynamically whilst carrying a mix of traffic – such as Ethernet, Sonet/SDH, Fibre Channel and video standards. They also want to better use each wavelength’s capacity by packing it efficiently with traffic. And operators want these needs met with platforms that use less floor space and power.
