Summary:An apparatus comprising: an optical transceiver comprising an optical transmitter and an optical receiver, the optical transceiver being configured to perform alignment of the optical transmitter and of the optical receiver, with respect to a remote optical device comprising a remote optical transceiver, and configured to perform bi-directional free-space optical data communication with the remote optical device; and wherein during the alignment, the optical receiver is configured to perform at least one of: filtering of electrical measurements of an optical signal received from the remote optical transceiver in a narrower frequency band than during the bi-directional free-space optical data communication; and optical mode demultiplexing of an optical signal from a multimode optical waveguide configured to receive the optical signal from the remote optical transceiver.
