18 September 2003 Munich Lightwave -- The Russian carrier OJSC (Open Joint-Stock Company) Rostelecom, Moscow, has awarded Siemens Information and Communication Networks (IC Networks) a contract to supply and install optical transmission technology. Rostelecom will be operating a more than 5,000-km transmission link between Novosibirsk and Khabarovsk with the optical platforms Surpass hiT 7500 for the long-haul domain and Surpass hiT 70xx series for the metro domain.
The new link will accommodate the Russian carrier's growing volume of traffic by boosting existing transmission capacities. Per the contract, Rostelecom is also planning to monitor the entire transport network with metro and backbone domains using the network management system from Siemens. Together with the Surpass hiT 7500 and Surpass hiT 70xx series products, this will mean economical transmission for the provider and new data service offerings for the customers.
The Surpass hiT 70xx series product family comprises end-to-end solutions for the metro core domain (Surpass hiT 7070), for the metro access domain extending out to large corporate locations (Surpass hiT 7050), and for individual customer locations (Surpass hiT 7030). The SDH-based Surpass hiT 70xx series meets the growing demand for new Ethernet-based data services in metro networks. The compact solution can be expanded end-to-end and allows increased transmission capacity to accommodate growing traffic and service volume.
Surpass hiT 7500 is a DWDM platform from Siemens for regional, long-haul, and ultra-long-haul applications that makes 100% optical add/drop multiplexers available as well as laser cards that can be tuned to up to 80 wavelengths. The platform can be expanded to up to 160 wavelengths with a capacity of up to 40 Gbits/sec per wavelength. The platform also supports the evolution to a purely optical meshed network.
