Dynamic optical fiber delivery of Ka-band packet transmissions for wireless access networks

A Reconfigurable Radio Access Unit is presented and experimentally demonstrated. In the unit, an optical switching system is set to dynamically deliver different packets to different points in the network. The packets are transmitted wirelesslty on the Ka-band (26-40 GHz), achieving BER values below the limit for 7% of overhead. The proposed system can easily be implemented in a centralized radio access networks (C-RAN) providing an extra degree of flexibility in 5G networks.
