A communication system, a terminating apparatus, and a method for PON(Passive Optical Network) virtualization are provided to simplify network architecture of the communication system by PON domain, and expand the PON logically without consuming a large number of MAC(Media Access Control) addresses. A communication system comprises a single physical PON. The physical PON includes a plurality of ONUs(Optical Network Units)(1a,1b,1c), an optical coupler(2), and an OLT(Optical Line Terminal)(3). The ONUs have LAN(Local Area Network) ports(11a,11b,11c) and PON ports(12a,12b,12c), respectively. The OLT has a plurality of LAN ports(31,32) and a PON port(33). The PON ports are connected in a star topology through the optical coupler by using optical fibers. The physical PON is used as a plurality of virtual PONs, which are obtained by virtually dividing the physical PON.
