| 摘要 |
The present invention relates to an Ethernet converting device of an Ethernet passive optical network (EPON), and a method thereof which can selectively convert specific packet data of downstream and upstream EPON frames to an Ethernet frame. The Ethernet converting device of an EPON comprises: one optical line terminator (OLT) which is installed in a backbone network; a plurality of optical network units (ONUs) which are installed in an area crowded by subscribers; a passive light distributor which distributes EPON frames transmitted between the OLT and each of the ONUs; and an Ethernet converting device which discriminates the downstream and upstream EPON frames, which are transmitted between the OLT and each of the ONUs via an optical cable, from each other, and selectively converts specific packet data into an Ethernet frame. According to the present invention, precise network management and monitoring can be performed on an EPON. |
