Global Crossing Quadruples Capacity on Wavelengths

Global Crossing, the network services operator that supports other carriers, enterprises and government organizations, has quadrupled the maximum capacity of its wavelength service to 40 Gigabits per second.

Florham Park, N.J.-based Global Crossing on Monday announced it is implementing the upgrade on terrestrial routes in Canada, Europe and the United States to meet growing demand for data virtualization, video on demand, VoIP and other applications that hog huge amounts of bandwidth.

Mark Manioci, director of transport product management for Global Crossing, told Channel Partners that the service is available at core” sites within the carriers points of presence and at edge” sites in several metropolitan areas, including New York City, Miami, Los Angeles and Seattle, where the company is connected to neutral colocation facilities.

The market is going to be going to 100 gigabits shortly,” Manioci said, but you have to wait for the demand to catch up with the technology.”

Global Crossing also announced that it is offering service-level agreements for so-called propagation delay” on wavelengths. In a press release, Global Crossing said propagation delay comprises the round-trip time required for a signal to travel the distance between two Global Crossing points of presence.” Carriers like Global Crossing measure such a period in time in milliseconds.

Manioci said Global Crossing will provide a credit, or in some cases, allow the customer to cancel the circuit if the company fails to meet an SLA.

Like private lines, wavelengths enable businesses to transport data from one location to another. Global Crossing sells private-line services that incorporate backup routes if a circuit goes down, Manioci said, but wavelengths are unprotected.” That means a customer could lose service on a wavelength circuit if there is a problem on the network, such as a cut in the fiber.

But Global Crossing on Monday also announced a diversity planning service” to prevent that from happening. The company said it is giving customers the option to assign an alternate, redundant route for wavelength circuits providing protection in case a circuit goes down. 

The customer can purchase an alternative circuit from Global Crossing or other communications providers, said Scott Ladin, Global Crossings senior product marketing manager for infrastructure.

Global Crossing said the service also provides assurance that routing will not be changed without the customers agreement.
