Ekinops introduces multiprotocol ADM capability for converged traffic transport

OCTOBER 16, 2009 -- By using the DynaMux dynamic multiplexing capability the Ekinops technique can accommodate a range of service types and rates over a single wavelength.

OCTOBER 16, 2009 -- Ekinops, an optical transport vendor for service providers and enterprises, has introduced a multiprotocol/multirate add/drop multiplexing (ADM) capability that it says will reduce the cost of aggregating converged traffic in business Ethernet, triple-play, wireless backhaul, and broadband backhaul applications.

The technology allows for many protocols (uncompressed video, Fibre Channel, Ethernet, SONET/SDH) and many different rates (ranging from as low as 10/100 or OC-3/STM-1) to be aggregated over a single 10G wavelength from multiple sites. In addition, Ekinops says this capability can utilize its high-density single fiber capability to cut infrastructure costs in half.

The capability can be used in ring and linear configurations. According to the company, it requires far fewer service cards to achieve aggregation of multiple service types.

Alternative transport methods require as much as an additional wavelength for each service type, but by using the DynaMux dynamic multiplexing capability the Ekinops technique can accommodate a range of service types and rates over a single wavelength to keep transport costs to a minimum. Alternative offerings without ADM capabilities require service cards to both add and drop traffic at remote sites. With the use of a multiprotocol/multirate drop and continue capability, Ekinops is able to reduce the hardware necessary to aggregate traffic at remote sites to a single service card.

Most transport today relies on two fibers to transport services bidirectionally, assigning one fiber to each direction. Ekinops also allows for the option to transport in both directions over a single fiber. In addition to transporting as many as 160 10G services over two fibers, the Ekinops 360 offers the option of transporting up to 32 10G or lower-rate services over a single fiber bidirectionally today. At the end of this month, Ekinops is expanding this to as many as 64 bidirectional 10G services over a single fiber using its WaveBonding 40G/100G technology.

"Carriers can save significantly on their infrastructure and capital costs by implementing our multiprotocol/multirate ADM," claims Rob Adams, vice president of global marketing and product line management for Ekinops. "Through elimination of fiber, wavelengths, and service cards that would typically be needed for this type of aggregation, we estimate that our customers can save as much as two-thirds over the cost of doing this with alternative technologies, depending on the number of aggregation sites and service types."

Ekinops reports that its multiprotocol/multirate ADM technology has been chosen for deployment by a European service provider.
