Abstract
According to an example aspect, there is provided an apparatus comprising a fibre interface coupled, via a first waveguide, with at least one encoder, a controller configured to cause the at least one encoder to encode light received in the apparatus via the fibre interface with information, and to cause a frequency shift in the light, and wherein the apparatus is configured to cause the light to propagate back to the fibre interface.
