Communications are booming. People are communicating more often, in more ways and with more places across the globe than ever before. Whether that communication takes place over the telephone, the Internet or via fax, the demand for infrastructure bandwidth is reaching all-time highs.
Service providers today are employing countless creative solutions to maximize their bandwidth, but new, easy-to-use technology will be what ultimately eases the pressure and breaks through bandwidth¹s barriers. That new technology is here today in the form of dense wavelength-division multiplexing, or DWDM.
The Tellabs TITAN Optical Transport System consists of one shelf of common equipment and up to two shelves of port interfaces.
DWDM leverages the benefits of synchronous optical networking (SONET) and synchronous digital hierarchy (SDH) networks by separating white light into its different frequencies or "colors," allowing more traffic to be transported without the need to add more fiber or bandwidth. The new technology, however, is not enough.
"While SONET and SDH provide for the high-availability bandwidth, ease of maintainability and provisioning that is needed today, there are many difficulties involved in expanding beyond today¹s SONET and SDH capabilities," says Brian J. Jackman, president of Tellabs Global Systems and Technology. "DWDM network elements must support end-to-end wavelength management -- in essence, they must provide optical networking capability."
The wavelength management that optical networking provides allows service providers to efficiently roll out existing services and troubleshoot network failures, as well as provide a new series of wavelength-based services. These new services may include wavelength handoffs, protection for currently unprotected data services and a means to easily scale bandwidth as customer needs expand.
That's where the new Tellabs TITAN 6000 Series of optical networking products -- and its first family member, the TITAN 6100 Optical Transport System (OTS) -- comes in, along with Tellabs' proven expertise in enabling cost-effective network evolution.
Delivering Optical Networking
The TITAN 6100 OTS is a next-generation, global optical networking platform that helps service providers deploy high-speed metropolitan area networks, while reducing network complexity and operations costs. Using DWDM technology, the TITAN 6100 system helps service providers initially boost network capacity by as much as 32 times.
The system carries 32 different wavelengths, or "colors," of voice, data and video traffic over a single fiberoptic pair. Each wavelength serves as a separate channel for carrying information over the same fiber. This multiplies the capacity of the fiber and enables service providers to expand bandwidth without adding more fibers.
The system's global SONET and SDH interfaces support speeds up to 2.5 Gbps, including OC-3/STM-1 (155 Mbps), OC-12/STM-4 (622 Mbps) and OC-48/STM-16 (2.5 Gbps) transponder cards. The optical port interface is software configurable to support multiple SONET and SDH line rates with an open, standard status response (SR) interface and is fully compatible with SDH at same rates.
"Delivering optical networking via the TITAN 6100 OTS allows carriers to manage the high-bandwidth pipes, or wavelengths, in their networks similar to the way they manage their SONET networks today," says Jackman. "This is achieved through a combination of lightpath management features and sophisticated management systems that track lightpaths through the entire network."
Tellabs' user-friendly, graphical user interface-based management systems manage the TITAN 6100 OTS. Based on the ITU telecommunication management network (TMN) model, all Tellabs element management systems run on Windows NT* and are designed with an open interface that allows seamless integration into existing management systems.
Users of telecommunications services have come to expect faster, more reliable service to keep pace with today's competition. Tellabs is there with the resources and technology that work and evolve with you to deliver the services your customers expect now and in the future.
The TITAN 6100 system's EMS provides multiple users with simultaneous management access to multiple TITAN 6100 systems. A PC-based CraftStation provides a single user with easy-to-use, portable management access to a single TITAN 6100 system at a time. The TITAN 6100 Lightpath Manager (LPM) is a powerful circuit management tool that enables effective end-to-end bandwidth management at the DWDM optical channel layer (lightpath) across multiple TITAN 6100 systems.
"The Tellabs 6100 Optical Transport System provides extensive, standards-based management capabilities not found in other DWDM systems today," says Rob Pullen, vice president of Tellabs Digital Systems Division Marketing and Development." The TITAN 6100 system brings a new level of sophistication to wavelength-division multiplexing in that operational and management functions required for optical networking will be integrated into the product, minimizing the need for manual intervention."
"Next-Generation" Defined
The Tellabs TITAN 6100 OTS is more than just a box that delivers DWDM technology. The TITAN 6100 system is the "next-generation" solution for optical networks because it can support mesh, ring and point-to-point applications in the same platform, giving service providers unparalleled flexibility.
Whether a service provider needs a 32-channel optical line terminal, an optical amplifier or an optical add/drop multiplexer (OADM), the TITAN 6100 system is designed to fill any or all of these needs in the network. The TITAN 6100 OTS uniquely supports physical mesh configurations beyond point-to-point (line terminal) or ring (OADM). Furthermore, tunneling of groups of wavelengths is handled economically.
Two or more TITAN 6100 Optical Transport Systems can be connected back-to-back, without transponders, enabling optical pass through of traffic that does not need to be terminated locally.
By eliminating extra transponders, service providers can significantly reduce capital costs and increase the reliability and flexibility of networked applications. And the terminals can be connected while in-service, without affecting the operation of other channels already deployed in the network.
"To deliver the same mesh pass-through capabilities, competitors must use back-to-back terminals linked by costly transponders. Or, they have to deploy add/drop multiplexers that only support ring configurations, requiring more elaborate planning with separate platforms," says Pullen. "The TITAN 6100 system¹s unique, single-platform flexibility allows it to protect the service provider¹s investment, minimize training and inventory costs, and reuse its components across multiple applications."
Flexible, Scalable Deployment
Delivery of DWDM optical networking via the Tellabs TITAN 6100 system allows service providers to leverage the benefits of SONET and SDH while providing an effective means for capacity and network expansion. The TITAN 6100 system is a single, scalable platform that can be used in access networks and metropolitan interoffice facilities. Carefully subdivided into functional building blocks, the TITAN 6100 system platform can be assembled in different configurations to provide various network solutions that can be scaled as needs grow.
The new TITAN 6100 Optical Transport System can grow hitlessly from one channel to 32 channels. Many point-to-point configurations require no optical amplification, but the optical supervisory channel is still supported.
The 32-channel optical add/drop multiplexer (OADM) configuration will allow the add-dropping any number of channels in any configuration. Moreover, the number and the configuration can easily be changed. Changing any channel from add/drop to pass through does not affect other channels.
The Wave of the Future
"Tellabs is known as a company dedicated to making the latest technology workable for its customers," says Jackman. "That 'workability' comes in the form of network elements, like the TITAN 6100 OTS, that not only meet industry standards but also provide the features, functionality and scalability that the customer requires."
The new the TITAN 6100 OTS is the first product in Tellabs TITAN 6000 Series of optical networking systems that incorporate the high standards of maintainability and reliability that service providers have come to expect from Tellabs.
"Where there used to be the capability to carry just one stream of data, optical networking of DWDM technology breaks through the barriers of optical bandwidth by providing much greater capacity and manageability without adding more fiber," says Jackman."For service providers to effectively address ever-increasing bandwidth demand, deployment of the TITAN 6100 Optical Transport System -- a complete optical networking solution -- is the wave of the future." |
