The power budget and costs are the two primary concerns for access networks. A major challenge is to minimize upstream power combining loss to increase the power budget. Spatial modes multiplexing offers the possibility to minimize upstream combining loss without significant added costs. We demonstrate the first integrated six-mode passive optical network, utilizing spatial modes to eliminate upstream...
We demonstrate combined wavelength- and mode-multiplexed transmission over a 125-km multimode single span composed of 10- and 15-mode fibers with a spectral efficiency of 29 b/s/Hz. A transmission capacity of 115.2 Tb/s is achieved over a distance of 87 km.
We demonstrate the first integrated 5-mode passive optical network, utilizing spatial modes to eliminate upstream combining loss. BERs of less than 10−9 were obtained for all 5 modes enabling Ethernet transmission using commercial GPON equipment without packet loss.
We demonstrate the first few-mode-fiber based passive optical network, effectively utilizing mode multiplexing to eliminate combining loss for upstream traffic. Error-free performance has been achieved for 20-km 3-mode transmission in a commercial GPON system carrying live Ethernet traffic.
