FTTH household terminal box and optical signal transmission apparatus including the same

Abstract

The present invention relates to a FTTH household terminal box having a tensile wire fixation part and to an optical signal transmission apparatus including the same. The optical signal transmission apparatus includes: a first tube on which a plurality of openings are formed at intervals and a second tube connected to the first tube; optical fibers which are accommodated in the first tube, have mutually different lengths and are drawn out through the openings different from each other to outside of the first tube; a tensile wire accommodated in the second tube; and a plurality of FTTH household terminal boxes which are configured in positions of the openings and are joined to the first tube and the second tube, and the optical fibers drawn out to the outside of the first tube are located inside the terminal boxes. Each FTTH household terminal box includes: a housing having the inside penetrated by the first tube and the second tube; and a tensile fixation part which is arranged in the housing and fixes the tensile wire.

Description

technical field [0001] The present invention relates to a FTTH (Fiber to the home, fiber to the home) junction box for home use and an optical signal transmission device including the same, in particular to an FTTH junction box for house use with a pulling wire fixing part and an optical signal transmission device (Fiber to the home terminal box for strength wire fixing parts shaving the same and apparatus for optical signal transmission including the same ). Background technique [0002] Optical cables are installed in public housing, buildings (hereinafter referred to as 'buildings'), etc., and transmit optical signals such as communication and information to each family of the public housing, each office of the building (hereinafter referred to as 'living space'), and the like. [0003] In the case of laying an optical cable in an aging building or a completed building, it is difficult to lay the optical cable inside the building because the design of the building must be...
