6400 OTP (Optical Transport Platform)

The Xtera 6400 OTP leverages a fully automated optical layer and intelligent control plane to provide a flexible, carrier-class WDM optical transport platform for both legacy SONET/SDH and Storage Area Network (SAN) applications, and emerging Ethernet and Multimedia services. The 6400 OTP is a field-proven Reconfigurable Optical Add/Drop Multiplexer (ROADM) which provides the foundation for leading Metro-Regional optical networks deployed around the world. This modular, integrated solution delivers Any Service to Any Port to Any Wavelength to Any Node in a cost-effective manner with minimum ongoing operational expense and maximum network resource efficiency.

The Xtera 6400 OTP ensures competitive advantage to network service providers who are expanding their services portfolio and scope while tightly managing their operational infrastructure and expenses. Having the right technology solution at the right time is no longer merely an added value, but is now critical to business survival. Agility and quality are the hallmarks of the 6400 OTP product family, which includes the smaller-scale 5400 OTP, seamlessly managed via the 8500 EMS and the unified control plane.

The Xtera 6400 OTP proactively addresses the increasing market demands for mixing a broad array of service types onto a common network infrastructure while managing bandwidth utilization and traffic dynamics. In addition to accelerating time-to-market, the 6400 OTP ensures that critical customer service level agreements are properly met and maintained. By using all-optical transport and grooming, 6400 OTP based services are not constrained by added throughput latency, switching fabric limitations, potential failure points and higher costs often associated with alternative Optical-Electrical-Optical (OEO) platforms. With the 6400 OTP it is now possible to future-proof your optical network today without having to roll trucks tomorrow.

Innovative Veriscolor™ – based architecture

The Xtera 6400 OTP integrated system supports two-fiber ring and linear configurations with up to 64 network nodes spanning a total of 750 miles or 1200 kilometers without requiring optical regeneration. Each node employs the Xtera patented Versicolor™ Wavelength Selectable Switch (WSS) ROADM to independently add, drop or pass-through 2.5G, 10G or 40G wavelengths all optically without OEO cost and performance penalties. Up to 32 wavelengths can be multiplexed onto a single fiber path yielding a total node capacity of 64 wavelengths with 32 per “east” and 32 per “west” facing fiber set. Due to this innovative Versicolor™-based architecture, individual wavelengths can be remotely provisioned without impacting neighboring wavelengths and without re-use restrictions. In addition, the wavelength specific power levels are continuously monitored and automatically adjusted for optimal end-to-end optical and service performance without operator intervention.

Integrated optical variable-gain amplifier – requiring no operator intervention

The Xtera 6400 OTP also includes integrated optical variable-gain amplifiers with automatic configuration to support a wide range of fiber types, span losses and transient conditions using Xtera patented techniques. No operator intervention is ever required to adjust the amplifiers for routine maintenance, transient events and span failures or restorals. To further optimize the optical network performance, optional in-span and mid-span dispersion compensation fiber modules can be directly interface as an integral element of the 6400 OTP solution. In addition to a number of optical network line-facing fiber interfaces, a broad suite of client-facing 2.5G and 10G (with 40G available in 2009) service transponders including fully tunable lasers and forward-error correction can be directly installed within the 6400 OTP to support ADM, GbE, SAN, video and 3R/2R any-rate traffic.

No impact on traffic flow

The Xtera 6400 OTP has power redundancy and is fully NEBS Level 3 compliant and utilizes a robust optical backplane which eliminates the need for labor-intensive, external optical jumpers which can be potentially damaged or improperly installed. The system utilizes fail-safe node controllers which do not impact traffic flow even if they were to be erroneously removed. By leveraging the resident GMPLS-based control plane and the embedded Optical Supervisory Channel (OSC), the entire network can be directly managed via local or remote access to a single node. Although each 6400 OTP node is fully self sufficient, the use of the graphics based 8500 EMS can further simplify end-to-end provisioning and reduce the need for in-depth operator technical expertise and ongoing training expenses. The client-server based 8500 EMS can similarly auto-discover and manage 5400 OTP nodes which may also be part of a 6400 OTP network.
