XKL enhances eVolocity platform for DWDM network, lit service handoff applications

Optical transport systems supplier XKL LLC has upgraded its eVolocity platform with features for DWDM networks and lit service handoffs, all across the same interface. The new capability enables network operators to connect physically separate private DWDM networks within a single eVolocity platform, thus improving network flexibility, XKL says.

The company introduced the eVolocity platform last year (see "XKL eVolocity combines coherent transmission, statistical multiplexing for 100-Gbps networks"). Now available in 1RU and 2RU form factors, the system can now be used to light dark fiber as well as interface to lit services over undersea cable, terrestrial, and aerial networks. Network operators also can use the platform to provide media conversion capabilities, which enable aggregation of 10 Gigabit Ethernet (10GbE) ports for transport on 100G DWDM wavelengths and on LAN-PHY interfaces. The platform's use of statistical multiplexing at OSI layer 1 enables aggregation of more client-side interfaces than standard 10x10GbE approaches would allow.

"Enterprise networks are increasingly separated from their data centers as facilities are established further away from corporate offices," said Dr. Chad Lamb, chief systems architect at XKL. "When dark fiber is not available to those remote locations, the eVolocity platform can access your proprietary network via lit services. This provides a great deal of flexibility for the customer in how the network is designed."
