JUNE 19, 2008 -- Tellabs (search for Tellabs) says the new capabilities of its 7100 OTS (optical transport system), including the 7100 Nano OTS, make deployments simpler and more efficient, with lower startup costs for service providers who must upgrade their networks in order to offer and support Carrier Ethernet services.
Reconfigurable optical add/drop multiplexing (ROADM) DWDM optical network components formerly mandatory are now decoupled and are optional on the Tellabs 7100 OTS family. Ethernet and SONET/SDH capabilities can be deployed without ROADM DWDM. The company says this flexibility simplifies provisioning and reduces startup costs for smaller applications while maintaining the ability to easily and cost-effectively upgrade to ROADM DWDM support as demand increases.
ITU-T Recommendation G.709 Optical Transport Network (OTN) based transport support will enable transparent high-capacity services. Providers can "carpool" their Carrier Ethernet, video, storage area network, SONET, and SDH services on a shared infrastructure, scaling capacity as needed.
Additional new capabilities enable more traffic to travel along optical highway lanes. Enhancements to traditional Ethernet over SONET/SDH transport enable a 20% increase in Gigabit Ethernet (GbE) port capacity and support 10GbE ports as well. More traffic on existing lanes improves service and network efficiency, says the company.
"These new capabilities of the Tellabs 7100 OTS enable our customers to upgrade their networks quickly," said Mark Pashan, vice president and general manager of optical transport products for Tellabs. "Ethernet services are more flexible, and users receive more bandwidth exactly where it's needed as network demands increase."
