DALLAS -- NFOEC -- Photuris, a developer of metro regional optical transport systems, launches its V32000 Optical Distribution System this week at NFOEC 2002. The purpose-built system delivers a fully automated optical layer, reconfigurable OADM and modular, carrier-selectable SONET/SDH add/drop functions. Together with intelligent optical amplifier features, these functions put wavelength deployment and management on par with the ease and familiarity of SONET. Systems are NEBS 3 qualified and shipping to carriers for trials and first office applications. "Photuris' V32000 addresses underserved metro regional transport needs in the WDM and TDM domains," states Ashish Vengsarkar, company co-founder and VP of Product Marketing. "These include reconfigurable OADM with single wavelength granularity; 'judiciously' integrated WDM and TDM; and wavelength/TDM-layer flexible protection. To achieve SONET-like simplicity, the system provides one-time node engineering, live node insert and jumperless provisioning." The V32000 includes four in-house innovations that distinguish it from all other transport devices:
Versicolor(tm) integrates four functions on a single optical line card: WDM demux/mux at the system input/output; fully flexible, reconfigurable OADM wavelength switching (any wavelength to any port, independent of any other wavelength); per-wavelength power balancing; and real-time per-wavelength optical power monitoring.
ADM-on-a-Wavelength(tm) line cards deliver the full functionality of a SONET ADM terminal, enabling transceivers to be added to hot-pluggable ports as services are activated.
VersiNET(tm) Software Suite includes VersiNET Engine intelligent network element software; automated network configuration; a GMPLS-based distributed control plane; VersiNET Planner optical layer configurator and traffic planning tools; and VersiNET Manager Element Management System (EMS), Command Line Interface (CLI), and Craft Interface Terminal (CIT).
Mix-and-Match Optical Layer Protection(tm) delivers granular and flexible protection at both the Optical and SONET layers on a per-wavelength selectable basis. This allows carriers to mix and match different protection schemes for diverse services and traffic patterns, on the same physical ring.
In a separate release: Photuris, a developer of metro regional optical transport systems, and White Rock Networks, a provider of next-generation optical transport systems for metro environments, announced today that they have successfully completed interoperability testing between Photuris' V32000 Optical Distribution System and White Rock Networks' VLX2010(tm) OC-48 SONET Add/Drop Multiplexer. At NFOEC 2002 this week in Dallas, Texas, the companies are demonstrating their implementation of an end-to-end metro-access and metro regional DWDM ring network with a fully automated optical layer. The demonstration highlights the simplicity of remotely provisioning both lightpaths and SONET circuits using the Photuris VersiNET(tm) Manager and the White Rock Networks VLXpert(tm) EMS systems. Point-and-click provisioning simplicity is accomplished using the GMPLS signaling protocols built into each solution. One of the most unique accomplishments of this effort is the flexible protection capability. When a fiber cut occurs on an LND unprotected lightpath, the Photuris V32000 appears entirely transparent to White Rock Networks' VLX2010 metro access nodes, which use standard SONET UPSR switching features to protect the traffic traversing that lightpath. For other wavelengths in the ring which use either dedicated or shared optical channel protection, the V32000 ring executes the appropriate protection scheme via Photuris' innovative Mix and Match Optical Layer Protection(tm). This per-wavelength selectable capability allows carriers to freely blend protection schemes on the same physical ring at a very granular level, thereby optimizing their service delivery quality and reducing overall network cost. In contrast, conventional WDM systems prohibit the mixing of dedicated protection, shared protection, and unprotected services on the same ring. Photuris Inc. White Rock Networks
