Over the past few years, Vtesse has

grown so rapidly that it has struggled to keep up with existing customers’ demands for service while responding to new opportunities. Vtesse executives decided they had to deploy an advanced networking solution that could enable the company to get—and stay—ahead of customer requirements. “One of the big advantages that

we have over larger competitors is our agility: our ability to react quickly to customer needs and turn up services just as quickly,” says Aidan Paul, Vtesse CEO. “As our growth accelerates, we needed a way to strengthen that advantage and Tellabs delivered just what we were looking for.”

What do you do if you’re growing so quickly that your network can’t keep up with demand? One good starting point is to enhance your optical network with more advanced technology—technology that can deliver the sophisticated services your customers need now and in the future. Better yet, what if that new technology comes from a

vendor that also helps you design new service offerings that take advantage of the capabilities of that technology? Capabilities such as helping capture new customers, increasing growth at those customers and improving customer retention? What if that vendor partner even has a lead- generation program to help kick-start your entry into new markets? In a nutshell, that’s the story of Vtesse Networks, a

fiber-based carrier in the United Kingdom. Primarily serving enterprise customers, Vtesse’s portfolio includes private optical networks, managed IP virtual networks, nationwide Ethernet connectivity, data centers, and co-location and hosting services.

optical network flexible enough that Vtesse can now turn up new, high-bandwidth services quickly across its entire network while reducing total cost of ownership. The operator now can go the distance—literally—when customers need connectivity to multiple locations scattered across the United Kingdom. To enable those capabilities, the Tellabs 7100 Nano OTS

combines multiple features into a compact footprint: • Flexible, seamless growth from white light configurations to fixed optical DWDM configurations to full multi-degree ROADM configurations

• Capability to handle virtually any service type (SDH, Ethernet, SANs) from 100Mbps to 40Gbps

• Integrated SDH switching, OTN Switching and Layer 2 switching.

The Tellabs 7100 Nano system’s design enables Vtesse to

extend cost-effective optical transport at speeds ranging from 100Mbps to 40Gbps at the network’s edge. By eliminating the need to purchase a separate ADM and Layer 2 switch, the Tellabs system also minimizes Vtesse’s CapEx requirements. Supporting a wide range of service modules, the platform

can operate as both an OLA and a node for reconfigurable or fixed optical adds/drops of up to 88 wavelengths. Vtesse can add/drop any of those 88 wavelengths remotely or, if using the OLA configuration, amplify all 88. That flexibility, combined with service-delivery modules that are 100% tunable across the C band, means Vtesse can provision nearly any service at the optical layer.
