Summary:A gigabit Ethernet line interface apparatus is provided to form many physical link ports through connecting with a network processor in a gigabit Ethernet linecard having a physical link interface and a system interface. A gigabit Ethernet line interface apparatus includes at least two physical link ports(112,116) selectively transmitting after converting inputted at least one gigabit Ethernet optical signal data to an electric signal. The physical link ports outputs after converting inputted at least one electric signal data to a gigabit Ethernet optical signal. At least two system interfaces is connected to a gigabit network processor card with a plurality connection interface to selectively output the electric signal data inputted through the physical link port to the gigabit network processor card. The system interfaces outputs data inputted from the gigabit network processor card through the connection interfaces to the physical link port. A mode setting unit(130) sets a communication channel ratio between the physical link port and the gigabit network processor card.
