Methods, apparatuses and systems for transporting multi-lane Ethernet signal are disclosed. The method primarily includes utilizing a plurality of timeslot channels and justification bytes configured in the OPUk-Xv to build up multiple virtually concatenated transport lanes; and transporting a lane of independent Ethernet data via each lane in the multiple transport lanes. Such schema allows to transparently transport multi-lane Ethernet signal over OTN and addresses the uncontrollability of the time delay occurred when multi-lane Ethernet signal traverse over OTN. In addition, the problem that the frequency offset does not fit the IEEE definition of the Ethernet interface is solved.
