Free space optics (FSO) is a wireless technology that utilizes optical frequencies. Previously available FSO transceivers are restricted to point-to-point links because of the high directivity of laser light used to transmit data. By contrast, various implementations disclosed herein include a multi-beam FSO apparatus that is less reliant on point-to-point links, and includes a lens assembly and a planar array of optical communication devices. The lens assembly includes at least one surface shaped to direct ingress light received substantially within a first angular range towards a focal plane, and to direct egress light away from the focal plane into the first angular range. The planar array includes a plurality of optical communication devices arranged in association with the focal plane of the lens assembly, wherein each of the plurality of optical communication devices characterizes at least one of a plurality of optical communication link endpoints. |
