摘要： Provided are a transmission apparatus and a transmission method for a subscriber network in a cable network. A passive optical network (GPON) receiver receives data packets through a fiber line using a plurality of optical wavelengths from a head end. A micro cable modem termination system (CMTS) converts the data packets into a data over cable service interface specification (DOCSIS)-based DOCSIS frame and transmits the DOCSIS frame to at least one subscriber device through a coaxial line.
