The OptCom group has carried out a thorough investigation of the so-called “symbol rate optimization” (SRO) strategy, which improves system performance by mitigating the impact of fiber non-linearity. The investigation was pushed to C-Band and showed that even in fully-loaded WDM systems SRO is quite effective. In fact, its effectiveness tends to grow with WDM bandwidth.

The OptCom group has carried out a ground-breaking experiment of ultra-long haul transmission, proving the effectiveness of the so-called “symbol rate optimization” (SRO) strategy to improve system  performance. 19 PM-QPSK channels at 128 Gb/s were sent over a link with 110 km span length and EDFA-only amplification. The fiber was PSCF, provided by SEC (Sumitomo Electric Industries). A system reach of over 14,200 km was obtained, with a 12.5% reach gain obtained through SRO, vs. conventional single-carrier transmission. SRO was implemented by subdividing each channel into subcarriers.

Hundreds of people has visited the PhotonLab booth during the 10th researchers' night held in Turin during the last Friday. The booth called "Occhio al Fotone" allowed kids and adults to play with light so as to learn some of the "superpowers" of light. Kids of all ages played with plastic optical fibers trying to transmit words and messages with light, and at the same time they learned the basic principles of optical fiber communications.

The European Researchers' Night celebrates its 10th anniversary this year. Whether with family, friends, your school, or on your own, you will have the opportunity to become a scientist for a day, discover different scientific disciplines and, most of all, have fun. All the events will take place - simultaneously - on 25 September, in 280 cities across Europe and beyond. Turin is no exception and the OptCom group will be present, today 25th of September in Piazza Castello, stand 15, to bring our research activities to you.
