Abstract: An installing method of an optical fiber communication conversion device is provided. The installing method includes the following steps. Firstly, a housing is provided. An opto-electronic converting module with a first cable winding structure is selectively accommodated and installed within the housing. An optical fiber wiring process is performed. If the opto-electronic converting module is provided and installed within the housing, an optical fiber cable managing function is implemented by the first cable winding structure. If the opto-electronic converting module is not installed within the housing, the optical fiber cable managing function is implemented by a second cable winding structure within the housing. The optical fiber communication conversion device using the installing method is also provided.

Abstract: A network device with an uninterruptible power supply function is provided. The network device includes a network physical transmission unit, a power connecting part and a backup power supply module. The network physical transmission unit is operated at a user terminal according to a fiber to the home (FTTH) technology or a fiber to the building (FTTB) technology. The power connecting part is in communication with an external power source for receiving electricity from the external power source to operate the network device. If the electricity transmitted from the external power source to the network device is interrupted, the backup power supply provides backup electricity to the network device to maintain normal operation of the network device.

Abstract: A data packet forwarding method and a network device using such a method in a network address translation mode are provided. The network device includes a central processing unit and a switch chip. The switch chip includes at least a wide area network port and plural local area network ports. The multicast packet is directly forwarded from said wide area network port to corresponding local area network ports. Since the central processing unit is not included in the forwarding path of the multicast packet, the speed of forwarding the multicast packet is enhanced.
