Xeta Group
Move bandwidth-intensive files across networks securely and quickly with fast optical connections
Xeta Group is a one stop shop for Optical Wavelength Services (OWS). Xeta Group has a relationship with a large number of network providers offering wavelength services and other connectivity solutions. Our product specialists are a free resource to organizations wishing to procure OWS. They narrow down your search by short listing providers based on important criteria – services offered, your proximity to providers' points of presence, compatible user interfaces, etc.

Because of our relationship with multiple providers, we are better positioned to negotiate pricing on your behalf. In addition to narrowing down your options and negotiating pricing, we work with you through provisioning and beyond implementation. Below is a detailed discussion of wavelength services for your perusal. What is optical wavelength service?

What Is Wavelength Services And How Does It Work?

What Is Wavelength Services?

Wavelength Services is an fiber optic based point to point, high bandwidth, delivery service, that helps you easily transport large data sets, files and apps between data centers and other facilities. Wavelength Services uses secure, private connections with high scalability and dedicated capacity to support your most data-intensive apps—like financial transactions, medical imaging and R&D information.

Wavelength services offer high security. It is secure enough to be used by very high security sensitive applications in the military and financial institutions. Because each data channel is separated from other data by wavelength (or frequency), there is no overlap in the data. Moreover, wavelength services are isolated from the public Internet. Static path and dedicated bandwidth.

Wavelength services come with protected or unprotected options. With the protected option, a redundant path is provided so that in the event of a cable cut or other catastrophic failure events, the service is automatically re-routed and does not go down. But redundancy comes at a premium and some clients may opt for the less expensive unprotected option.

Like many other dedicated network services, OWS comes with an SLA which specify a number of attributes including availability, latency and jitter. Typical availability levels range from 99.5% to 99.999%. Because wavelength services are point to point optical services without any optical to electric conversion along the path, they have low latency and low jitter.

How Wavelength Services Works.
Optical Wavelength Service is a shared Dense Wave Division Multiplexing (DWDM) architecture which provides dedicated circuit bandwidth in a point to point configuration utilizing Reconfigurable Optical Add Drop Multiplexer (ROADM) technology. The service allows individual or multiple wavelengths carrying data channels to be added and/or dropped from a transport fiber without a need to convert the signals.

Using Dense Wave Division Multiplexing (DWDM) technology, multiple high bandwidth channels can be transmitted in a single strand of fiber. When multiple businesses share a pair of fiber strands, the cost of the service is drastically reduced relative to the cost of deploying and maintaining fiber infrastructure. In DWDM, data is encoded on multiple laser transmitters each at a unique wavelength (or frequency). Corresponding laser pulses are multiplexed together into a composite signal and transmitted in a single optical fiber. At the distal end of the fiber, the signal is separated into the constituent wavelength components by a de-multiplexer and directed to relevant wavelength sensitive receivers. Because of the wide spectrum of the optical communication transmission window, up to 96 very high bandwidth channels can be transmitted in a single strand of fiber.

Optical Wavelength Service supports SONET (OC3, OC12, OC48, OC192 and OC768*) Ethernet (Gig E, 10G LAN PHY, 10G WAN PHY, 40GbE, and 100GbE) and Optical Transport Network (OTN) (OTU1, OTU2, OTU3, AND OTU4) interfaces/protocols.

Dedicated bandwidth options are from 1 to 100 Gbps (with potential for 200 Gbps) customized, priced and deployed to unique needs and budget.

Wavelength Services are primarily available in the following 3 options from providers:

1. Standard Point-to-Point Wavelengths:
Single unprotected fiber circuit terminating at the customers premises on a Fiber Distribution Panel. Maintain control with dedicated bandwidth and predictable latency.

Domestic Wavelength Services:

Domestic wavelength services are provisioned to connect locations within the same county. To connect locations in San Francisco and Chicago with a wavelength service, businesses typically use a national long haul fiber optic network provider. There are relatively fewer providers who can offer domestic wavelength services and this could have a profound impact on the pricing. International wavelength services:

International Wavelength Services:

International (or non-domestic) wavelength services connect points in different countries or continents. For locations in different continents, provisioning of International OWS will take a combination of undersea and terrestrial networks. Organizations may have only a limited number of providers that can meet their requirements. We are available to point you to providers who can connect your geographically dispersed locations.

Wavelength Service Applications:

Wavelength services are suitable for applications requiring high data rate transmission, especially when the cost of deploying and maintaining infrastructure is deemed too high. The following is a sample of suitable applications.

  • Business continuity and disaster recovery
  • Data center interconnection
  • Credit card processing and other financial applications
  • High resolution (4K and 8K) video streaming
  • Research and educational networks (RENs)
  • Manufacturing data transfer Transfer of high resolution imaging data in health
  • The capturing and processing of cosmic signals in astronomy (e.g Square Kilometer array)
It's OUR business to keep NETWORK running smoothly.
