Movaz deploys multi-degree ROADM network

October 31, 2005 Atlanta, GA -- Movaz Networks has announced in-service deployment of its Multi-Degree RAY-ROADM network. According to a press release, an integrated switching core has been established, linking multiple networks with the company's multi-degree ROADM platforms. The optical DWDM transport and mesh reconfigurable network provides extended reach to sites including the NASA Goddard Space Flight Center, Mid Atlantic Crossroads (MAX), and the National LambdaRail.

The company says its Multi-Degree RAY-ROADM network offers three advantages over older generations of ROADM systems. According to the company, the first is the ability to optionally add single or multi-degree ROADMs when and where such capability is needed by service add/drop requirements. Without having to predict and pre-install for unknown future traffic patterns, stranded equipment is eliminated and initial capital expenditures are minimized. Secondly, support for in-field upgrades from single to multi-degree on the same shelf platform ensures that the equipment deployed will not have be moved out in the future to support multi-degree switching. The third benefit is the platform's operational simplification and software automation, says the company.

According to the release, Mid Atlantic Crossroads (MAX), in conjunction with the National Science Foundation (NSF), began the multi-phased deployments of the ROADM platform over a year ago. The RAY-ROADM was first configured as a 1x1 ROADM in a mixed ring configuration with Movaz's RAYexpress product, deployed either as standalone nodes or as subtending service terminating shelves. With this system, MAX and NSF have been able to support time critical e-Science applications, which require the ability to dynamically groom, route, and transport "light path" services in a variety of formats including SONET OC-192, 10 Gigabit Ethernet, Fiber Channel, and Packet IP, as well as native wavelengths. Further enhancing the system is a sophisticated GMPLS control plane embedded in the Movaz ROADM element to ensure any service on the "light path" can be instantaneous set up on an as needed or pre-scheduled basis.

"Phase 1 of project, code named "DRAGON" for Dynamic Resource Allocation over GMPLS Optical Networks, was established in 2004, containing the Movaz iWSS Optical Cross Connect and RAYexpress. This network successfully demonstrated all-optical per-lambda routing and rapid wavelength," explains Jerry Sobieski, principal investigator of the NSF DRAGON project. "In July of 2005, Movaz upgraded into this network its multi-degree RAY-ROADMs, and we have successfully turned up services, on what we believe to be the first truly all-optical system."

According to Movaz, the RAY-ROADM platform is a universal shelf, containing integrated switching modules, pre/post amplifiers, and Optical Performance Monitoring (OPM) cards. The core of the platform's multi-degree switching module is based on the company's exclusively patented technology, which the company says enabled it to fully integrate 1xN MEMS arrays with electronic drive ASICs in a chip-like packaging.

"The uniqueness of the Movaz RAY-ROADM originates from its highly integrated packaging of optics, ASICs and MEMS in an extremely compact form factor. With this, Movaz is able to eliminate the conventional design of multiple interconnected switching shelves, and truly deliver the economic values of a ROADM network as well as greatly simplified network operations," remarks Bijan Khosravi, chairman and CEO of Movaz Networks. "The multi-degree RAY-ROADM accomplishes a major element of the Movaz vision in delivering a multi-faceted all-optical network with DWDM, optical switching, and GMPLS Control Plane."

The company will showcase the RAY-ROADM platform at November's SuperComputing 2005 conference in Seattle, Washington.
