Cisco Upgrades ONS 15454 Optical Platform

Cisco announced significant hardware and software upgrades to its Cisco ONS optical networking platform, including a new 40-channel, mesh reconfigurable optical add/drop multiplexer (ROADM) supporting from 2 to 8-degrees of dense wavelength-division multiplexing (DWDM) traffic, Ethernet Xponder and Cisco Multiservice Provisioning Platform (MSPP)-on-a-blade.



Cisco said its mesh ROADM now supports a service provider's migration from ring-based DWDM topologies to more fiber-efficient mesh DWDM topologies.



The new Cisco Ethernet Xponder provides aggregation of 1-Mbps up to 1-Gbps Ethernet into G.709, 10-Gbps wavelengths for delivery to Cisco routers such as the Cisco CRS-1 Carrier Routing System-based IP-over-DWDM solution. This enables service providers who have already deployed the Cisco ONS 15454 platform for other services to add a blade to provide Ethernet aggregation services in remote central offices.



The Cisco MSPP on a blade enables full MSPP Synchronous Optical Network (SONET)/Synchronous Digital Hierarchy (SDH) functionality to reside on a single card inside a Cisco MSTP DWDM chassis.

Cisco noted that more than 75,000 Cisco ONS 15454 systems have been deployed.
