The present invention discloses a method for multicast, processing, including: when replicating downlink multicast data, an Optical Line Terminal (OLT), on which a same port is connected to different types of Optical Network Units (ONUs), replicates the multicast data to different broadcast or multicast logical channels according to the ONU types of users who join a multicast group. The present invention also discloses a device for multicast processing. The present invention achieves efficient multicast processing when different types of ONUs coexist, therefore preventing excessive data from unnecessarily interfering with the ONUs, meanwhile, efficiently utilizing the bandwidth between an OLT and an ONU, and avoiding the meaningless bandwidth occupation by data streams.
