Description

本発明は、戸建住宅、ビル構内などの建物内に布設された光ファイバケーブルを相互に接続する場合に用いられる可動式光コネクタであって、光コネクタの接続端面が、光ファイバ長手方向に対して回動する光コネクタ回動部を具備する可動式光コネクタ、及び前記可動式光コネクタを用いて光ファイバケーブルを建物内に布設する光ファイバケーブル配線方法に関するものである。   The present invention is a movable optical connector used when optical fiber cables laid in a building such as a detached house or a building are connected to each other, and the connection end face of the optical connector is in the longitudinal direction of the optical fiber. The present invention relates to a movable optical connector having an optical connector rotating portion that rotates relative to the optical connector, and an optical fiber cable wiring method for laying an optical fiber cable in a building using the movable optical connector.

従来の技術としては、戸建住宅、ビル構内などの建物内に布設された光ファイバケーブルを相互に接続する場合、光アダプタを介し、双方の光ファイバケーブルの先端に設置されたＦ０４形単心光ファイバコネクタのＳＣ形光コネクタなどの光コネクタを光ファイバ長手方向にＰＣ（Ｐｈｙｓｉｃａｌ Ｃｏｎｔａｃｔ）接続する方法がある。   As a conventional technique, when connecting optical fiber cables installed in a building such as a detached house or a building, the F04 type single core installed at the tip of both optical fiber cables via an optical adapter. There is a method of connecting an optical connector such as an SC type optical connector of an optical fiber connector in the longitudinal direction of the optical fiber by PC (Physical Contact).

光アダプタを介した光コネクタの接続方法だけでは、戸建住宅、ビル構内などの建物内に光ファイバケーブルを相互に接続して布設し、ホームネットワークを構築する際には、不十分である。   The connection method of the optical connector via the optical adapter is not sufficient for constructing a home network by connecting and laying optical fiber cables in a building such as a detached house or building.

図５は従来のホームネットワーク用の光ファイバケーブル配線方法を示す斜視図である。戸建住宅、ビル構内などの建物内の壁等には、光アウトレット１１が設けられる。この光アウトレット１１内には配管により幹線ケーブルが引き込まれ、光アウトレット１１のフェースプレート前面には光コネクタ用接続部１２が設けられている。前記光コネクタ用接続部１２にＳＣ形光コネクタ１３の接続端面を挿入接続することにより、ＳＣ形光コネクタ１３に接続された配線ケーブルと前記幹線ケーブルを接続している。しかしながら、幹線ケーブルと配線ケーブルを接続する際には、光アウトレット１１のフェースプレート前面にＳＣ形光コネクタ１３を大幅に突出させるしかない。そのため、光アウトレット１１の近傍では、美観を損ね、外的環境による影響を受ける可能性が高くなり、運用および保守上の問題があった。   FIG. 5 is a perspective view showing a conventional optical fiber cable wiring method for a home network. A light outlet 11 is provided on a wall in a building such as a detached house or a building. A trunk cable is drawn into the optical outlet 11 by piping, and an optical connector connecting portion 12 is provided on the front surface of the face plate of the optical outlet 11. By inserting and connecting the connection end face of the SC-type optical connector 13 to the optical connector connecting portion 12, the wiring cable connected to the SC-type optical connector 13 and the trunk cable are connected. However, when connecting the main line cable and the wiring cable, the SC-type optical connector 13 has to be greatly projected on the front face of the face plate of the optical outlet 11. Therefore, in the vicinity of the optical outlet 11, there is a high possibility that the aesthetic appearance is impaired and the influence of the external environment is increased, and there are problems in operation and maintenance.

また、従来のＳＣ形光コネクタ同士を光アダプタを介して接続し、建物内に光ファイバの配線ケーブルを布設する場合、入隅、出隅などの曲部では、配線ケーブルの接続点での許容曲率半径を確保し、配線ケーブルと壁などに間隙が生じるため、入隅、出隅部近傍での美観を損ね、外的環境による配線ケーブルへの損傷を受ける可能性が高くなり、運用および保守上問題があった。さらに、ホーム（建物）形態の差異により、配線ケーブルの接続点では、様々な角度（あるいは方向）が存在するため、従来のＳＣ形光コネクタでは不十分であった。   In addition, when connecting conventional SC optical connectors via optical adapters and laying optical fiber wiring cables in the building, bends at the corners of the entrance and exit corners are permitted at the connection points of the wiring cables. Ensuring a radius of curvature and creating a gap between the wiring cable and the wall, etc., impairs the appearance near the entrance and exit corners and increases the possibility of damage to the wiring cable due to the external environment. Operation and maintenance There was a problem above. Furthermore, due to the difference in the form of the home (building), there are various angles (or directions) at the connection points of the wiring cables, so the conventional SC type optical connector is insufficient.

It is characterized by comprising.

また本発明は、前記可動式光コネクタにおいて、光コネクタに内蔵される光ファイバとして、カットオフ長及びモードフィールド径値が小さい特定のファイバパラメータを有する光ファイバ、もしくはハイデルタ型光ファイバあるいはホーリー光ファイバなどの許容曲率半径の小さい光ファイバを用いることを特徴とするものである。   According to the present invention, in the movable optical connector, as an optical fiber built in the optical connector, an optical fiber having a specific fiber parameter having a small cutoff length and mode field diameter value, a high-delta optical fiber, or a holey optical fiber.
