Abstract
An apparatus 100 is configured to transmit an optical signal. The apparatus 100 comprises a first optical signal generator 102, configured to generate a first optical signal 106 comprising a first set of characteristics; a second optical signal generator 104, configured to generate a second optical signal 108 comprising a second set of characteristics; an adjustment unit 110, configured to adjust at least one of the different characteristics of at least one of the first and / or second optical signals 106, 108; and an optical signal combiner 116, configured to combine the first and second optical signals 106, 108 into a combined optical signal 118. The first and second sets of characteristics are different. Also described herein is an apparatus 200 configured to receiving an optical signal 202. The apparatus 200 comprises at least one sensor 204, configured to detect a combined optical data signal 202; and a processor 208. The processor 208 is configured to identify, from the combined optical signal 202, a first optical signal based on a first wavelength component; identify, from the combined optical signal, a second optical signal based on a second wavelength component; and extract data from the first optical signal based on the second optical signal. Also described herein is a method of transmitting 600 and a method of receiving 700 an optical signal, for example, using the transmitter and receiver apparatuses 100, 200.
