Cisco has upgraded its ONS 15454 Multiservice Transport Platform, to help improve service delivery, network scalability and management at enterprises and service providers.
The ONS 15454 MSTP is Cisco's flagship metro optical transport system. There are more than 75,000 deployed, according to Cisco.
Speculation has been rampant in recent years that Cisco would exit the optical business. Cisco's other optical platforms, such as the ONS 15800 long-haul Dense Wavelength Division Multiplexing (DWDM) gear and ONS 15900 wavelength router, have reached end-of-life status.
But optical grew 40 percent year-over-year in the second quarter of Cisco's fiscal 2007, so the company is riding the fortunes of the ONS 15454 and the metro optical market for now.
The enhancements to the 15454 include 40-channel Reconfigurable Optical Add/Drop Multiplexing (ROADM), Ethernet Crossponder (Xponder) and a Multiservice Provisioning Platform (MSPP)-on-a-blade.
The ROADM functionality supports a service provider's migration from ring topologies to more fibre-efficient mesh DWDM topologies while also simplifying provisioning and troubleshooting, Cisco said.
The Ethernet Xponder provides aggregation of 1 Mbit/s up to 1 Gbit/s Ethernet into G.709-compliant 10 Gbit/s wavelengths for delivery to Cisco routers. This is intended to enable service providers that have deployed the ONS 15454 platform for other services to add a blade to provide Ethernet aggregation services in remote central offices, Cisco said.
The MSPP-on-a-blade enables MSPP SONET/SDH functionality resides on a single card inside a Cisco MSTP DWDM chassis. It is designed to assist service providers to migrate from SONET/SDH services to DWDM services in the same ONS 15454 chassis, thereby protecting their ONS 15454 investments, Cisco said.
