Shenandoah selects Cisco's Coherent DWDM technology
Aug 23, 2013 (MarketLine via COMTEX) --
Cisco, which designs, manufactures, and sells internet protocol-based networking and other products, has announced that Shenandoah Telecommunications Company, a telecommunications service provider, has updated its dense wavelength division multiplexing, or DWDM, fiber-optic network with Cisco's Coherent DWDM technology to support 100 Gigabit per second speeds to its subscribers throughout Virginia, West Virginia and Maryland. The Cisco ASR 9000 Series router will provide IP services.
Shentel updated its existing Cisco network to 100G coherent DWDM, which offers plug-and-play-like functionality that can be configured to meet a customer's demand for bandwidth. This elastic core is optimized to provide multiple 100G support, as required, and supports customer demand for multiple 10G service on-demand.
As Shentel continues to build or partner to expand its fiber network, the company's highly flexible and scalable new Multi-Degree Reconfigurable Optical Add-Drop Multiplexer (MD-ROADM) DWDM 100G network can be expanded further into its Virginia, West Virginia and Maryland markets quickly and without requiring new hardware.
Recognizing the continuing rapid growth of IP traffic on its network, Shentel has reportedly begun deploying the Cisco ASR 9000 platform. Since the first deployment in 2010, Shentel has been upgrading its Cisco7600 network to the ASR 9000. The Cisco ASR 9000 will serve as the foundation for next-generation Carrier Ethernet networks, providing up to 96 terabits (Tbps) per system, allowing Cisco to evolve its service provider architecture to deliver capabilities for the Next-Generation Internet, which must be more mobile, more visual, more virtual, and more simple to manage. This architecture will allow carriers to monetize new, profitable services; optimize network performance and efficiency; reduce operational costs and complexity and enhance customer experiences, Cisco said.
The 100G DWDM solution is based on coherent optical technology, powered by Cisco's nLight Silicon. It provides the capability to transmit up to 100G wavelengths over fully uncompensated networks, up to 3,000 km (1864 mile) optical spans without regeneration. Utilizing an advanced modulation scheme and enhanced forward error correction enables Shentel to use its existing fiber plant investments while delivering maximum performance, especially on marginal or impaired fiber segments, Cisco reported.
According to Cisco, all parameters of the DWDM network were configured automatically by the smart-management subsystem and optical channel power control tools integrated in the Cisco ONS 15454 MSTP platform.
The Cisco ASR 9000 Series utilizes the modular Cisco IOS XR software operating system, simplifying network operations while enabling comprehensive system redundancy and intelligent routing. Shentel has widely deployed the Cisco ASR 9000, family, which contains high-density 10G and 100G interfaces for the network edge.
The Cisco ASR 9000 Series routers used as Shentel's network core providing up to 96 terabits (Tbps) per system, helping ensure the fail-safe delivery of multifunctional applications, Cisco added.
Sri Hosakote, vice president and General Manager, High-end Routing and Optical group, Cisco, said: "The rapid pace of M2M connectivity across people, places and things, in addition to continued demand for high-bandwidth content, requires service providers to rethink their technology infrastructures to ensure they remain relevant. Shentel has great foresight to complete this initiative now to address current and projected internal and external requirements. They are ahead of the curve and have an even stronger foundation to deliver new and enhanced services."
