Description

METHOD FOR SUPPLING INFORMATION AND COMMUNICATIONS APPARATUS WITH ELECTRICITY}

The present invention relates to a method for supplying power to an information communication device for constructing a high speed multimedia network, and a method of operating the same. More particularly, a power supply method for supplying power to a plurality of information communication devices with a single power supply device. It is about.

In the construction of an optical subscriber network for providing subscribers with high speed multimedia services,

In order to provide high-speed multimedia services to subscribers, optical subscriber networks must be established. To this end, the existing copper wire is limited due to signal transmission constraint distance, and the optical transmission device should be installed near the subscriber.

The optical transmission device must be provided with an independent power supply because service must be provided continuously even in the event of power failure.

When providing a low speed service (telephone service), a remote power supply method using a telephone line was used, and when providing a high speed service (ultra-high speed multimedia service), a local power supply method in which an optical transmission device was located in a subscriber area was used.

As shown in FIG. 1, the remote power supply method is a method in which information and communication devices receive power from a telephone station directly through a power transmission copper cable 2 and used in the same manner as a signal transmission copper wire.

As shown in FIG. 2, the local power supply method is a method in which power is directly supplied from a place where information communication devices are installed. The local power supply method is to receive power from the optical transmission device directly from the installed site and to receive power from commercial power near the installation site. That is, even if the optical cable 3 is newly installed due to the application of the optical transmission device to provide a high speed service, the copper cable for power supply does not need to be newly installed.

On the other hand, in order to provide ultra-high speed multimedia service to general residential subscribers or small businesses, it is desirable to provide a service as a small capacity optical transmission device rather than the existing large capacity optical transmission device due to the limitation of distance according to the local conditions of the subscriber.

However, the existing optical power transmission devices using local power supply method have a rectifier and backup battery even though they are small in size, causing them to be constrained by the installation space due to their large volume and weight. Due to the increase in operating and maintenance costs.

Accordingly, the present invention is to solve such a conventional problem, to provide a backup power by gathering the battery in one place by supplying power to a plurality of small optical transmission device to a single shared feed point, remove the battery from the optical transmission device By reducing the volume and weight of the optical transmission device to provide a power supply method for information and communication equipment that can be installed on the pole or wall.

The present invention for realizing the above object is a method of supplying power to an information and communication device for building a high-speed multimedia network, shared power supply having a shared power supply system that can accommodate the power capacity of a plurality of optical transmission devices The apparatus supplies power to a plurality of optical transmission apparatuses installed on the subscriber side, and the shared power supply apparatus provides a method for power supply of information and communication equipment, which is managed remotely at a telephone station.
