As NBN executives look to get Australian’s onto their 100Gbps fibre network German operator Deutsche Telekom is now striving to hit speeds of between 400 and 512Gps.
In a traial last week the carrier was able to achieve a data transmission rate of 512Gbps. The real-world speed was achieved over a single optical fiber channel over a 734km (456mi) distance between Berlin and Hannover and back again. The project, dubbed Optically Supported IP Router Interfaces (OSIRIS), was performed by DT’s Berlin-based T-Labs team.
Electronista said that Deutsche Telekom claimed that the usable per-channel bitrate would be limited to 400Gbps, though this would still be a four-fold increase over the 100Gbps speeds afforded by modern networks.
With 48 channels available in the fiber strand used in the T-Labs system, it should still theoretically result in total throughput of 24.6Tbps at its peak. DT compared the speeds to sending the music stored on 3,696 CDs at the same time on a single optical fiber.
DT also stated that existing network only need new end equipment rather than all-new cable to achieve these speeds. Timelines for the rollout of the technology aren’t immediately available, however, as network gear makers need to adopt the technology. Source Electronista
