Já pensou o mundo sem infraesturas de comunicações? Pois, é uma situação quase inimaginável! Segundo consta, em Setembro de 1940, George Stibitz usou uma máquina de teletipo para enviar instruções para um conjunto de problemas a partir de seu Model K na Faculdade de Dartmouth em Nova Hampshire para a sua calculadora em Nova Iorque. Em 1969, a ARPA (Advanced Research Projects Agency) desenvolveu a ARPANET que muito apelidam como a rede “mãe” da Internet.
A partir daí muita coisa mudou…muito mais largura de banda, mais e diferente tráfego, rede sem fios etc. Recentemente a empresa telefónica Escandinávia TeliaSonera anunciou que tem vindo a realizar alguns testes que permitirão ter redes informáticas a terabit.
TeliaSonera, uma empresa telefónica Escandinávia informou recentemente que tem vindo a desenvolver alguns testes no sentido de implementar redes de dados com transmissões a terabit, com base em “super canais ópticos” de 500 Gbps. Um “super canal” é uma grande unidade de capacidade óptica, criada pela combinação de múltiplas portadoras ópticas, transportadas num único meio de transmissão – tipo cloud óptica.
Segundo a própria empresa, os testes foram realizados com sucesso entre Los Angeles e San Jose, na Califórnia, num distância total de 1.105 Kms. Anteriormente a própria empresa já tinha realizados alguns testes mas com super canais ópticos a 300 Gbps.
Press Release TeliaSonera
STOCKHOLM, SWEDEN and SUNNYVALE, CA — (Marketwire) — 11/07/11 — TeliaSonera International Carrier and Infinera (INFN) announced today the successful completion of the world’s first Terabit optical transmission based on 500 Gigabit per second (Gb/s) super-channels. The demonstration spanned 1,105 kilometers of fiber between Los Angeles and San Jose, California, marking a milestone in optical networking and offering a glimpse of what the network will be. The trial was conducted with elements of the new Infinera DTN-X platform and demonstrated twice the capacity of previous trials by adding a Terabit of capacity to a route carrying 300 Gb/s of production capacity.
“Our vision is to offer customers leading-edge services that efficiently scale their business. As 10 Gb/s services proliferate and 100 Gb/s router ports emerge, we are trialing advanced solutions that scale optical networks beyond 100 Gb/s,” said Erik Hallberg, President at TeliaSonera International Carrier. “This Terabit demonstration with Infinera highlights our commitment to delivering an outstanding experience for the most demanding customers.”
“We are delighted to work with TeliaSonera International Carrier to validate the 500 Gb/s super-channel implementation that is the foundation of this Terabit demonstration,” said Tom Fallon, CEO of Infinera. “We share a common vision of delivering the scale, simplicity and agility needed to win in a highly competitive environment.”
Infinera is a pioneer in the field of super-channels, and the first to demonstrate super-channels based on 500 Gb/s photonic integrated circuits (PICs). A super-channel is a large unit of optical capacity created by combining multiple optical carriers into a single managed entity, so that optical networks can scale capacity without scaling operational cost and complexity. Super-channels based on PICs enable operators to simply provision 500 Gb/s of capacity with a single operational maneuver. Infinera’s DTN platform, ATN platform and Infinera Managed Services are elements of Infinera’s portfolio as well as the recently announced DTN-X packet optical transport network platform that supports 500 Gb/s super-channels.
TeliaSonera International Carrier is part of Europe’s 5th largest telecommunications group, TeliaSonera, with 164 million subscribers generating revenues of over $11 billion. The company continues to expand the North American footprint of their global network, driven by strong demand from both operators and content players for IP, DWDM, voice and specialist-mobile services.
