Intelligent WDM (iWDM) technology is used in Infinera’s XTM Series metro solutions and provides cost-optimized transport of multiple services while simplifying the provisioning and operations of optical transport networks. iWDM also provides unique advantages in terms of service transparency and support for multiple high-quality synchronization domains.The ability to support multiple services, and the quality of these services, is key to metro networks. iWDM provides a range of features found in other techniques, such as forward error correction functionality for extending the reach of a system and performance monitoring for service level agreement maintenance. It supports multiple services and provides aggregation to the most cost-efficient transport bit rate, including 2.5, 4 or 10 gigabits per second (Gb/s) depending on the application. For example, the 10x Multi-Service Muxponder supports up to 10x Gigabit Ethernet services and therefore 25 percent more data capacity than 8x solutions, and also supports independent transparent Synchronous Ethernet (SyncE) support on each of the 10 ports.
iWDM provides a patented automatic client protocol and bit rate detection that reduces an operator’s operational expenditure by removing the need for complex installation, commissioning and provisioning. It also provides in-band management capabilities that simplify the management of remote network elements.
