Glimmerglass - Intelligent Optical Switching solutions for Fiber Optic Communication

Glimmerglass develops and markets Intelligent Optical Switching solutions for the Telecommunications Industry and Government. Glimmerglass has shipped more than 40,000 optical cross connect ports to over 50 customers across Europe, Asia and North America.

The demand for video and streaming media services by service providers, national carriers and content providers are driving bandwidth demand. This has resulted in the exponential growth in Internet traffic. Service providers are looking for Intelligent Optical Switching to meet the ever growing requirement at today’s market and for the future solutions.

The solutions from Glimmerglass have the capability to Create, Monitor and protect fiber-optic light paths. Customers can utilize effectively the Glimmerglass solutions in five major application areas providing dramatic reductions in operational expenses, OPEX, and capital expenses, CAPEX, while increasing network capacity.

Glimmerglass identifies those five areas of major applications as given below;

Increasingly complex fiber plants and reduced OPEX budgets require innovative solutions. Using Glimmerglass Intelligent Optical Switches to manage light paths enables "lights out" data centers. In the New Optical Internet, Central Offices are becoming overloaded with fiber. Connected by high speed fiber-optic links to the rest of the Internet, they are the major aggregation and disaggregation points and, with the rapid growth of FTTx, the customer links are also increasingly fiber-based. Managing these external optical links is an increasing problem. Rapid growth in both the number and speeds of these links, combined with the need for increased reliability and flexibility, must be handled in a very cost-constrained environment.

Glimmerglass Intelligent Optical Switches add major flexibility in the management of light paths while enabling significant reductions in both OPEX and CAPEX. Visionary telecommunications carriers and researchers recognize that a hybrid of routers and optical switches provides the most efficient and highest capacity Internet backbone infrastructure.

One major European carrier has deployed Glimmerglass solutions to protect all wavelengths at the juncture of the undersea cable and the land-based fiber plant. Undersea fiber-optic cables provide the vast majority of the intercontinental bandwidth of the Internet. Remotely Creating, Monitoring and Protecting the light-paths on these fibers is increasingly important to the New Optical Internet. With the rapid growth in the amount of traffic carried on undersea cables, the outages seen in the past caused by cable breaks and equipment failures are no longer acceptable.

Peering Exchanges are the most data intensive sites in the world. AMS-IX, Europe's largest Internet Exchange, relies on Glimmerglass switches in the heart of its hybrid IP/ switched network to provide the ability to create new light paths on demand and to monitor and protect all high speed links.

An Internet Exchange is a meeting point for independent Internet Service Providers (ISPs) enabling them to exchange Internet traffic with each other, nationally and internationally. This exchange of traffic is known as “peering.” Since without peering, the Internet is nothing, network reliability at Internet Exchanges is of extreme importance. In addition, rapid growth of the Internet has resulted in Internet Exchanges seeing traffic double every year. This places a severe strain on both network architecture and planning.

Glimmerglass Intelligent Optical Switches provide the optimal monitoring environment for lawful intercept and other government applications.

Signals monitoring and analysis demand the highest possible optical signal quality over a wide range of conditions. The use of pure optics with no electrical conversions enables Glimmerglass Intelligent Optical Switches to deliver the best possible performance — independent of signal type. Glimmerglass solutions are non-blocking, deliver very low optical insertion loss (typical 1.7 dB), support a wide range of signals on single mode fiber (1260 nm–1630 nm) and operate with ultra low input power (-35 dBm).
