The Xtera 7200 OSP provides a single, high density, cost-effective transport protocol-agnostic switching system. It combines WDM transport of an OADM with transparent wavelength (layer 0) switching, sub-wavelength aggregation/switching (L1), and VPN/tunnel switching of ethernet services (L2) switching/cross-connect functionality.

The 7200 OSP offers industry-leading optical WDM switching solutions and flexible support for Packet Optical Transport solutions for high-capacity optical transport networks. It utilizes multi-degree switching to aggregate multiple DWDM or CWDM data transport links from different linear networks, multiple access rings, or mesh network links, in the process eliminating back-to-back OADM nodes between rings or linear access networks.

With industry-leading GigE aggregation density per shelf, the 7200 OSP offers service providers a choice of single GigE per wavelength, dual GigE per wavelength, or 9 GigEs per wavelength of full wire-speed optical transport ideal for high-volume wireless backhaul, IPTV transport, or high-capacity GigE aggregation and back-haul to one or more data-centres.

The 7200 OSP also supports switching of GigE services onto or out of OC-192/STM-64 transport wavelengths throughout the network, eliminating the need for hair-pinning of client ports.

The 7200 OSP allows fully transparent transport for minimum latency applications, sub-wavelength aggregation/switching for optimal wavelength utilization, and powerful L2 switching at the tunnel level to provide either connection-less or connection-oriented ethernet transport. In a typical application the 7200 would connect to , and aggregate a number of smaller sites . These sites would use smaller access multiplexors such as Xtera’s 3300 Optical Service Multiplexor (OSM) to connect the Ethernet and legacy transport services into the network. The 7200 OSP product utilizes highly flexible hardware and software architectures designed to support any existing or future ethernet transport protocols. This ensures that any Packet Optical Transport solution deployed using the 7200 OSP is future-proof, to accommodate whichever direction ethernet transport protocols evolve by means of a simple software update.

Benefits include:
Integrated remote electrical loopbacks for centralized testing and trouble-shooting eliminating truck rolls
Layer 1 Performance Monitoring on all client and line-side services
Automatic protection switching based on both PM thresholds and LOS
Integrated add-drop multiplexing of a wide-range of 8B/10B data protocols, GigE, SAN, SONET, SDH protocols onto a single wavelength
Industry leading GigE aggregation support and density per shelf
L2 Transport Protocol-Agnostic allowing support of multiple Packet Optical Transport Protocols to switch L2 Tunnels and providng QOS/COS facilitating enforced service-level agreements for ethernet services end-to-end across both transport and access networks
Multi-degree support and switching for inter-ring, multiple access ring aggregation or full mesh networking support
Carrier-Grade Architecture Optimized for high-resiliency
The Xtera 7200 OSP provides a very high density solution for optical service backhaul, ideally suited for metro-hub, or metro-core applications where high-reliability and high capacity are required.

The 7200 OSP offers the ability to use one node type to offer:

Extremely low latency transparent wavelength connections for video and SAN transport applications
Industry-leading GigE aggregation and back-haul using dual 9:1 SRM cards to carry high-volumes of GigE traffic at full wire-speed
Rate-limited (100M, 200M, 300M, etc.) GigEs transport with rate enforcement and sub-wavelength switching at each site
Optimized wavelength packing at each hop through the network of low-rate SONET/SDH and GigE traffic using sub-wavelength switching
L2 tunnel switching to reduce tromboning
Whichever next generation L2 Ethernet transport protocol meets your needs to provide encapsulation, policing, shaping and switching for optimized Packet Optical Transport support
The 7200 OSP allows fully transparent transport for minimum latency applications, sub-wavelength aggregation/switching for optimal wavelength utilization, and support for a selection of powerful L2 protocols switched at the tunnel level to provide either connection-less or connection-oriented ethernet transport.
