Previously, the researchers at Alcatel-Lucent have broken records in speed by sending data at a speed of 25.6Tbps. This transfer was only 50 miles long and the company is now looking for a distance record. They recently performed a great feat by sending data over a whopping 1584 mile link at 16.4Tbps. This was accomplished by bundling many 100 Gbps cables together at different wavelengths. The signals were then split at the receiving end (I hope by a hardware decoder, I have a feeling that using a computer to decode the signal might cause it to slow down.) The most recent trial required 164 different channels and updated transmitters and decoders.
