Abstract

PURPOSE:To make the titled device small in size and light in weight by allowing an external feeding slave station to offer all or a part of power to an optical subscriber terminal device using an optical fiber. CONSTITUTION:Subscribers are gathered at a block and a station 2 feeding power to subscriber terminals, called the feeding slave station is placed in the unit of blocks for feeding. A center station 1 and a subscriber station (b) are communicated through the optical fiber. Since external feeding is applied to the subscriber terminals, it is not required to provide a battery for power failure in the inside of the terminals.

軽量化ができる効果がある。An embodiment of the present invention will be described below with reference to FIG. According to this embodiment, subscribers are grouped into blocks, and a station called an electronic power supply station that supplies power to subscriber terminals is placed in each block to supply power. The center station and subscriber stations communicate via optical fiber as before. According to this configuration, since external power is supplied to the subscriber terminal, there is no need to have a battery inside the terminal in case of a power outage, and the device can be made smaller.
It has the effect of reducing weight.
