Practically all the countries of the world are interconnected by very long optical fibre wires that support spectacular transfer speeds. Beyond submarine cables, Europe has backbone networks that use the Photonic Service Engine (PSE-V) for nokia for interconnect data centers. Now, the company has managed to improve the speed of that network.
Using the fifth generation of the PSE-V In a real test, Nokia has announced that it has reached a transmission speed of 600Gbps. The test has been carried out on the terrestrial network of GlobalConnect Go-Color for data center interconnection services in the Nordic countries. The trial validates GlobalConnect’s plan to upgrade its long-distance backbone networks to the Nokia 1830 PSI-M optical transport system.
600 Gbps at a distance of 781 km
In the test, Nokia demonstrated error-free performance of up to 600Gbps at a distance of 781 kilometers. In it, they used eleven sections of fiber And six ROADM nodes with teams Colorless Directionless Connectionless and Flexgrid (CDC-F). Signals were sent over 100 GHz WDM channels, which offer exceptional efficiency. The network could be scaled to a total capacity of 28.8 Tbps through the C+ band.
The 600 Gbps speed is only guaranteed for certain distances. However, the system can reach speeds of up to 400 Gbps over any distance through 100 GHz, helping to reduce network costs and energy consumption for each bit that passes through the cables.
The importance of ICDs
The data center interconnect (DCI) it is a key part of the fast and efficient operation of the Internet. This part allows two installations to share resources. In the past, they were used as backup networks, but today they are used to more efficiently manage resources and spread loads.
Thanks to DCI, companies can scale their infrastructure as Internet traffic increases. In the past, the networks interconnected more with the rest of the Internet, but recently the traffic has increased between the data centers, hence faster connections between these centers are increasingly required than external connections to the rest of the Internet.
This also allows a improvement in security, since the exchange of information is done encrypted and among other DCI with equivalent security measures. For this reason, the speed improvement in these interconnections will allow us to enjoy more stable services with more capacity for the future. Currently, networks also use the PSE-Vc, where the “c” stands for “compact”, and which reaches speeds of between 100 and 400 Gbps.
