Source Photonics and Credo demo Single Lambda 100G at 20km

A new generation of single wavelength 100G trancseivers is a step closer. Whereas currently deployed 100G optical transceivers rely on 4x25G WDM technology, the next generation of transceivers will use higher order modulation techniques, such as PAM4, and higher data rate operation at 53Gbaud. This means that that one laser and one receiver could do the job that currently requires four lasers and four receivers. In addition to 100G-DR/FR/LR, Source...

Toshiba's Cambridge Research Lab Sets Quantum Encryption record

Quantum cyptography is postulated to be unbreakable. However, the quantum key must be held by the receiving party for the encrypted message to be deciphered. Until now, the speed at which a quantum key can be distributed has been limited to 1.9 Mbps. Toshiba Research Europe Limited’s Cambridge Research Laboratory in the UK has just announced a new data distribution speed record of 13.7 Mbps - seven times the previous record, which was also achieved...
