Exar Samples Industry’s First ODU0/ODUflex Muxponder Solution

Exar has begun offering today the industry’s first OTN muxponder solution that supports new G.709 features such as ODU0/ODUflex and GMP mapping. Exar’s MXP2 ASSP is a low power, 8 Watts, 2 x 10G single chip solution that was specifically designed to help customers future-proof their networks with support for the newest OTN standard features.



The data explosion coupled with the growing roll-out of packet-based networks has driven the OTN standard to include support for many client signals and the flexibility of mapping to different container sizes. Ultimately the new features help alleviate data traffic congestion and increase the effectiveness of the network whether it is Metro, WAN, LAN or Wireless Backhaul. The MXP2 ASSP, with support for the new G.709 features, provides any service, on any port with any mapping enabling OEMs to expand their ROADM or Edge Services product offerings to include support for Gigabit Ethernet, High-definition Video and SAN protocols.



“The market has been waiting for suppliers to ‘catch up’ and support the multi-signal requirements they need in today’s data-intensive, always-on environment,” said Rich Deboer, vice president and general manager at Exar. “The MXP2 ASSP delivers on these requirements and as we have heard from our customers the market is ready to embrace OTN.”



The MXP2 ASSP is a highly integrated, standards based device targeted at ROADM/DWDM and Edge Aggregation platforms in OTN transport applications. With flexible client ports supporting a wide range of protocols and frequencies, MXP2 enables development of any service-any port line cards and consolidation of a number of service specific muxponders (e.g. 10 x GE or 8 x OC-48/STM-16) into a single, flexible, universal design. The new G.709 features supported in MXP2 including ODU0, ODUflex and GMP, enable services (e.g. Gigabit Ethernet) to be mapped to size appropriate OTN containers and multiplexed in a single multiplexing stage (e.g. directly to ODU1 or directly to ODU2). The dual network interfaces support protected line cards in ROADM/ DWDM equipment. OTN ADM/ring functionality is supported with internal switching of ODU0/ODU1/ODU2/ODUflex containers. Similarly, SONET/SDH ADM/ring functionality is provided by internal STS-1/VC-4 switching.



The MXP2 comes standard with Exar’s DeviceManager software package for rapid integration with minimal design effort. The DeviceManager handles all internal hardware provisioning and management details and presents a robust set of APIs for use by the customer. Software features include OS independence, integrated tools, interrupt management, state management, resource pool management and warm start. Comprehensive documentation, integrated HTML, PDF and source comments, make the software easy to integrate and dramatically shortens the overall project development cycle.
