The Bell Labs, Alcatel-Lucent’s research unit made significant progress regarding its aim to push the limits of capacity of optical networks, at a time they struggle daily to respond to the explosion of expected traffic with the arrival of 5G networks and the Internet of Things.
According to a study by Bell Labs , telecom operators and businesses are seeing a rapid growth in network data traffic. The annual cumulative rate already exceeds 100 percent. With the technology promise Wireless 5G on the horizon, Bell Labs estimates that in the next ten years there will be a pressing need for commercial optical transport systems capable of supporting a capacity of around petabits per second.
Before this reality which threatens to exceed the capacity limits of current fiber optic networks, Bell Labs have just presented an optical networking technology that can help operators endereçarem this expansion: an optical system MIMO-SDM real-time (Space- Division Multiplexed Multiple-Input-Multiple-Output).
The world’s first demonstration of this pioneering technique MIMO-SDM Bell Labs has the potential to increase the current capacity of fiber 10-20 Terabits-per-second for a capacity of petabits-per-second – equivalent to 1,000 Terabits / s. The successful experience MIMO-SDM 6 × 6 in real time which used six transmitters and six receivers in combination with a digital signal processing in real time, was carried out on 60 km of fiber in the coupled mode, the seat Bell Labs in New Jersey.
Through technical MIMO-SDM , the Bell Labs intend to exceed the capacity limits imposed by the ‘limit of Shannon’ not the current linear optical fiber. This sets the fundamental limit to the maximum rate of information transfer over a single optical fiber used in today’s metropolitan networks and in long current distance transport networks
Relevant Facts:.
- The Bell Labs demonstrated the prototype of an innovative technology in the world – a MIMO system optics 6 × 6 real-time transmission – that will push the boundaries of optical transport capacity networks to meet the great future requirements.
- Through MIMO-SDM technique, Bell Labs plan to overthrow the Shannon limit is currently implemented in the linear optical fiber. During the technology experience transmission MIMO 6 × 6 in real-time interference from multiple signs of a special fiber with support for six pathways of parallel optical signal is removed for the first time through real-time processing. This breakthrough puts closer to reality technology, compared with experiments carried out previously that used off-line processing.
- The MIMO-SDM technique has the potential to increase the current capacity of fiber to the petabits-per-second -. sufficient capacity to support simultaneous streaming of HD movies for two-thirds of the population in the United States, a single optical fiber
- Alcatel-Lucent announced the commercial availability of single-carrier 100G technology in June 2010, and the commercial launch of the 100G line card / single-carrier 200G in 2014, with capacity to support up to 24 Tbps capacity. In 2013 Alcatel-Lucent announced the first implementation of an optical connection 400G (supercanal), in partnership with Orange FT, with a capacity of 17.6 terabit-per-second, based on the 400G Photonic Service Engine (PSE) . jointly developed with Bell Labs
Following this breakthrough, Marcus Weldon, CTO of Alcatel-Lucent and president of Bell Labs said: “This experience represents a major advance for the development of the future of optical transport. We are in the center of a huge change in communications networks, with the arrival of wireless 5G networks and the network cloud on the way. The networks of traders and companies will face a big challenge – the large increase in traffic. At Bell Labs we remain focused on our commitment to innovation and creating the future of communication networks in order to get better meet the high demand and all the requirements. “
