A high bit rate free space optics based ring topology having carrier‐less nodes
IET Communications, Volume 15, Issue 11, Page 1530-1538, July 2021., 2021 Abstract A free space optics based ring topology that transmits full‐duplex data to four different nodes in the ring is proposed. The link is designed such that the four nodes do not require a local optical source to transmit the uplink data. A wavelength division multiplexed signal composed of four different wavelengths each modulated by the downlink ...
