Re­sea­rch news from the In­sti­tu­te of Elec­tri­cal En­gi­nee­ring and In­for­ma­ti­on Tech­no­lo­gy at the Uni­ver­si­ty of Pa­der­born

 

The "backbone" of the whole internet and telephone net consists of optical fibers. For transmission capacity doubling each optical wavelength may carry two signals with mutually orthogonal vibration directions. For the first time, Prof. Noé and his Optical Communication and High-Frequency Engineering group have realized such a polarization division multiplex data transmission system with an automatic optical compensator of polarization mode dispersion, thereby making this technology practical. The system transmits data of two polarization channels with 40Gbit/s each, i.e., together 80Gbit/s or 80.000.000.000 bit per second, over a 212km long optical fiber - much further than otherwise possible. The experiment has been reported on at the European Conference on Optical Communication in Amsterdam as a post-deadline paper.
