XKL Announces the Launch of its 100GE Coherent Product Suite, eVolocity

Platform Uses a first-of-its-kind Layer 1 algorithm that allows for the dynamic allocation of bandwidth

KIRKLAND, WA–(Marketwired – Oct 19, 2016) – XKL LLC, a leading provider of fiber optic networking systems, announces the launch of its 100GE coherent product line eVolocity. The eVolocity platform provides up to 96 channels of coherent 100GE and 9.6 terabits of line-side bandwidth per fiber pair. eVolocity maximizes line utilization and uses statistical multiplexing to flexibly allocate capacity on a per client basis. The platform provides a bandwidth-on-demand solution in a high port density, 1RU form factor.

eVolocity was developed by XKL’s team of accomplished engineers and spearheaded by the company’s CEO and founder, Len Bosack. Ideal for data center interconnect, metro and long haul transport, the eVolocity platform uses a first-of-its-kind, OSI Layer 1 statistical multiplexing algorithm that allows for the dynamic allocation of bandwidth on an as-needed basis. The virtualized interfaces enable seamless capacity growth as customer demands increase. The eVolocity platform maximizes line utilization, allowing customers to run at full line rates. The statistical multiplexing feature supports flexible bandwidth allocation, with physical ports soft-assigned priorities, providing QoS controls.

“Spectral efficiency is essential for optical networking solutions,” says Bosack. “In addition to this, eVolocity is engineered to prioritize and allocate customer data intelligently, thus minimizing idle capacity. This dynamic bandwidth allocation is unique for Layer 1 and provides another means for customers to handle the explosion in bandwidth growth. Customers are looking for additional methods to get more data through the fiber. Spectral efficiency improvements via more complex modulation formats alone will not get the job done.”

“As with all XKL products, eVolocity is designed with the future in mind,” adds Chad Lamb, Director of Engineering for XKL. “Typical channel utilization of 50% or less leads to a large amount of unused Layer 1 capacity, eVolocity enables customers to reclaim this lost bandwidth. On top of this capability, we are using standard, off-the-shelf, 100GE coherent transceivers and, as coherent technology improves, we’ll integrate these enhancements into the product line. XKL customers will be taking advantage of both improved spectral efficiency in the optical domain, and superior efficiency in channel utilization. This is the XKL differentiator.”

eVolocity key features:

  • Provides 100GE coherent line-side optics with 240Gb of client-side connectivity in a compact 1 RU form factor
  • Bandwidth-on-demand with packet shaping using statistical multiplexing
  • Digital ROADM and FlexArc technology, provides Add/Drop functionality in addition to point to point, ring and mesh topologies
  • Low power consumption and smaller footprint, reducing recurring costs
  • Offers bandwidth management at Layer 1, providing QoS for data demanding applications
  • Interoperable with lit service or dark fiber
