Abstract
A method performed by second fronthaul network unit for enabling synchronization with a first fronthaul network unit over a first single optical fiber in a fronthaul network is provided. The method includes receiving a first optical signal on the single optical fiber; and separating the received first optical signal into a second optical signal carrying downlink, DL, radio data traffic having a first optical wavelength and a third optical signal carrying packet-based synchronization messages having a second optical wavelength. The method further includes outputting the separated second optical signal towards a first optical port in the second fronthaul network unit; and splitting the separated third optical signal towards a second optical port in the second fronthaul network unit. A second fronthaul network unit, and a first fronthaul network unit and method therein are also provided.
