Abstract:
1. An optical network system, comprising: at least one symmetric optical subscriber terminal; at least one asymmetric optical subscriber terminal; and an optical base station to control a passive optical network in which the at least one symmetric optical terminal and the at least one asymmetric optical subscriber terminal coexist, wherein an upstream signal from the at least one symmetric optical subscriber terminal and the at least one asymmetric optical subscriber terminal is based on one of a upstream transmission speed and a downstream transmission speed, and an optical clock signal is extracted from the upstream signal, wherein the optical base station further comprises a physical medium attachment (PMA) configured to alternatively output an asymmetric output or a symmetric output from one to a plurality of output signals, wherein the PMA is configured to output only one output signal when the output signal is configured to be asymmetric, and the PMA is configured to output the plurality of output signals when the output signal is configured to be symmetric.
