XKL LLC, best known for supplying easy-to-use optical transport systems for private network applications, is expanding its addressable market by targeting its eVolocity platform at submarine networks. The company will use next week's Pacific Telecoms Council (PTC) event in Honolulu, HI, to launch a version of the platform that XKL says will facilitate optical protection via protected LAN PHY links, DWDM links, or both.
The eVolocity uses statistical multiplexing to provide aggregation and protection, XKL explains. This feature enables the system to pre-provision operational links to which circuits can be automatically switched in the event of failure. The approach enables the protected path to pass primary traffic and backup traffic. When the troubled link is restored, traffic can be routed back to the link either automatically or manually.
The eVolocity platform reduces recurring costs because it is designed for efficient deployment on submarine networks and easy manageability, XKL adds. Operators can connect physically separate LAN PHY services, alien wave applications, or dark fiber as well.
The system can provide significant benefits for existing submarine networks, says the company. "Even though the new fiber builds launched this year and next are receiving considerable attention, it is possible to get high performance out of legacy cables," explains Chad Lamb, chief systems architect for XKL. "The eVolocity platform allows customers to extend capacity of existing networks using soft-assigned priorities along with statistical multiplexing to provide QoS control, dynamic bandwidth allocation, and maximizes the customer line utilization. The cost of line-side optics continues to dominate the overall costs of DWDM networks. eVolocity allows customers to get the most out of these investments."
