I will join the home network.

광선로종단장치의 기능은 도1에서 보는 바와 같이, 중간단자함이나 외부의 노드(Node)에서 분기되어 댁내로 들어오는 광케이블(10)을 내부에서 성단처리하여 광어댑터(14)와 광접속시켜, ONU, 광 스위치와 같은 외부 기기와 광접속을 이루는 것이다.As shown in FIG. 1, the function of the optical fiber terminator is the optical cable 10 branched from an intermediate terminal box or an external node to enter the home, and internally connected to the optical adapter 14 to optically connect the optical adapter 14 to the ONU, Optical connection is made with an external device such as an optical switch.

심선가이드(109, 110)는 원통형, 반달형 이외에 실패형 보빈(bobbin), 도넛형 등 필요에 따라 다양한 형상을 갖는 것이 가능하다. The core guides 109 and 110 may have various shapes as necessary, in addition to the cylindrical and half moon types, such as a bobbin or a donut type.

광어댑터 홀더(104)와 광어댑터(107)의 결합에도 끼워맞춤 이외에 스냅핏(snap-fit), 자석결합, 벨크로, 나사결합 등 착탈에 적합한 결합방법이라면 어떠한 것이라도 사용할 수 있다.In addition to fitting to the coupling of the optical adapter holder 104 and the optical adapter 107, any combination method suitable for detachment such as snap-fit, magnet coupling, velcro, screw coupling, and the like can be used.

도7을 참조하여 광케이블(120)이 인입되어 광인출되는 공정을 설명한다. 광케이블(120)은 복수의 광인입구(106)중 하나로 인입되어 광케이블 고정구(107)에서 고정된다. 이 때, 통상적으로 광케이블 클램프(121)에 의한 고정 방법이 주로 사용되게 되나, 이외에 공지의 다른 광케이블 고정 방법 예를 들면, 케이블 타이로 광케이블을 묶거나, 아라미드 선을 고정하거나 하는 방법도 사용될 수 있다.Referring to FIG. 7, a process in which the optical cable 120 is drawn in and drawn out will be described. The optical cable 120 is introduced into one of the plurality of optical inlets 106 and fixed at the optical cable fixture 107.
