Titel
140 Mbit/s FSK heterodyne multichannel TV-transmission/distribution system over 11 km of installed fiber with the capability of supplying 256 subscribers
Abstract
A 140 Mbit/s CMI line coded FSK coherent optical TV-distribution multichannel experiment is described. The system works over 11 km monomode-fiber, which is installed between the Heinrich Hertz Institut and the broadcasting station SFB. The system uses an all-fiber optical polarization diversity frontend, an all-fiber polarization independent supervisor unit and has a sensitivity of -47.8 dBm even at an IF linewidth of more than 80 MHz. System performance measurements are shown for a period of 54 h.
