Abstract
Description
本発明は、光コネクタ端面の簡易で効果的な清掃方法に関する。 The present invention relates to a simple and effective cleaning method for an end face of an optical connector.
光コネクタは光ファイバを接続させる用具であり、その端面は常に清掃されている必要がある。これは光コネクタの端面が汚れて異物が付着していた場合には、光ファイバへ入射すべき光または光ファイバから出射すべき光が当該異物によって遮られる等して、結果として接続損失となるからである。 An optical connector is a tool for connecting an optical fiber, and its end face must always be cleaned. This is because, when the end face of the optical connector is dirty and foreign matter adheres, light that should enter the optical fiber or light that should exit from the optical fiber is blocked by the foreign matter, resulting in connection loss. Because.
従来の光コネクタ端面の清掃には、超極細繊維の清掃布を用いる方法、セルロース製長繊維不織布を用いる方法等が知られている。超極細繊維の清掃布を用いる方法として具体的は、NTT−AT社製の商品名OPTIPOPシリーズが例示でき、この技術は特許文献1に開示されている。しかし清掃布または不織布を用いる方法では、異物を拭き取るという動作であるために、清掃布等に付着した異物により光コネクタ端面に傷をつける場合があった。特に光ファイバまたは光コネクタが樹脂製であった場合に、光コネクタ端面に傷をつける可能性が指摘されていた。 For cleaning the end face of the conventional optical connector, a method using a cleaning cloth of ultrafine fibers, a method using a cellulose long fiber nonwoven fabric, and the like are known. A specific example of the method using the ultrafine fiber cleaning cloth is the trade name OPTIPOP series manufactured by NTT-AT, and this technique is disclosed in Patent Document 1. However, in the method using a cleaning cloth or a non-woven fabric, the operation of wiping off foreign matter has caused the optical connector end face to be damaged by foreign matter adhering to the cleaning cloth or the like. In particular, when the optical fiber or the optical connector is made of resin, it has been pointed out that the end face of the optical connector may be damaged.
また圧搾空気等のガスを光コネクタ端面に吹き付けて異物を除去することも行われている。しかしこの方法では、光コネクタ端面の汚れが充分に除去されない場合がある。 Further, foreign substances are removed by blowing a gas such as compressed air on the end face of the optical connector. However, this method may not sufficiently remove the dirt on the end face of the optical connector.
本発明の目的は、光コネクタ端面に傷をつけることなく、簡易で効果的な端面の清掃方法を提供することにある。 An object of the present invention is to provide a simple and effective end face cleaning method without damaging the end face of the optical connector.
前述の課題を解決するために本発明は、光コネクタ端面を粘着面に接触させることにより、該光コネクタ端面の異物を該粘着面に付着させることを特徴とする、光コネクタ端面の清掃方法を提供する。この清掃方法は、前記光コネクタに接続された光ファイバがプラスチック製光ファイバである場合に特に好適である。 In order to solve the above-mentioned problems, the present invention provides an optical connector end face cleaning method, wherein the optical connector end face is brought into contact with the adhesive surface by bringing the optical connector end face into contact with the adhesive face. provide. This cleaning method is particularly suitable when the optical fiber connected to the optical connector is a plastic optical fiber.
本発明は光コネクタ端面を清掃する際に拭き取る動作を採用しないため、除去された異物により光コネクタ端面が傷つけられることが防止できる。また拭き取る動作に起因する静電気の発生も抑制され、ほこり等の異物の付着も防止できる。また用具も簡単であり、複雑な手順が必要ない点で優れる。さらに光コネクタ端面に平面的に付着して拭き取りでは除去しにくい異物であっても容易に除去できる点で優れる。 Since the present invention does not employ an wiping operation when cleaning the end face of the optical connector, the end face of the optical connector can be prevented from being damaged by the removed foreign matter. In addition, generation of static electricity due to the wiping operation is suppressed, and adhesion of foreign matters such as dust can be prevented. In addition, the tool is simple and is excellent in that a complicated procedure is not necessary. Furthermore, it is excellent in that it can be easily removed even if it is a foreign substance that adheres to the end face of the optical connector and is difficult to remove by wiping.
本発明は、光コネクタ端面を粘着面に接触させることにより、該光コネクタ端面の異物を該粘着面に付着させることを特徴とする、光コネクタ端面の清掃方法である。ここで光コネクタ端面とは、光ファイバと、該光ファイバを保持するフェルール等の保持具とを組み立てた後の端面であり、通信用の光が入出射する面を意味する。ただしフェルール等の保持具の側面(曲面)の清掃に本発明の方法を適用することを妨げない。 The present invention is a method for cleaning an optical connector end face, wherein the foreign substance on the end face of the optical connector is attached to the adhesive face by bringing the end face of the optical connector into contact with the adhesive face. Here, the optical connector end face is an end face after assembling an optical fiber and a holder such as a ferrule that holds the optical fiber, and means a face on which light for communication enters and exits. However, application of the method of the present invention to cleaning of the side surface (curved surface) of a holder such as a ferrule is not prevented.
前記光ファイバとしては、石英製であってもプラスチック製であってもよい。特にプラスチック製光ファイバを用いた場合の光コネクタ端面の清掃に、本発明の清掃方法は好適である。プラスチック製光ファイバとしては、アクリル樹脂製光ファイバ、透明フッ素樹脂製光ファイバ等が挙げられる。また前記フェルールとしては、ガラス製フェルール、セラミックス製フェルール、樹脂製フェルール等が例示できるが、特に樹脂製フェルールを用いる場合に好適である。 The optical fiber may be made of quartz or plastic. In particular, the cleaning method of the present invention is suitable for cleaning the optical connector end face when a plastic optical fiber is used. Examples of the plastic optical fiber include an acrylic resin optical fiber and a transparent fluororesin optical fiber. Examples of the ferrule include a glass ferrule, a ceramic ferrule, and a resin ferrule, and are particularly suitable when a resin ferrule is used.
また本発明において粘着面とは、粘着性を有する面であり、平面であっても曲面であってもよい。ここで粘着性を有する面を持つ具体的なものとしては、粘着テープ、粘着性を有する樹脂ブロック等が挙げられる。粘着テープとしては例えば、マスキングテープ、セロハン製テープ、ガムテープ等が例示できる。粘着性を有する樹脂ブロックとしては、ゲル状のウレタン樹脂ブロック、シリコン樹脂ブロック等が例示でき、具体的にはオンゾウ・ラボ社製の商品名ゼロダスト・スタイラスチップクリーナー(レコード針のクリーナー)が挙げられる。 In the present invention, the adhesive surface is a surface having adhesiveness, and may be a flat surface or a curved surface. Specific examples of the adhesive surface include an adhesive tape and an adhesive resin block. Examples of the adhesive tape include masking tape, cellophane tape, and gum tape. Examples of adhesive resin blocks include gel-like urethane resin blocks, silicone resin blocks, and the like, and specific examples include zero dust stylus chip cleaner (record needle cleaner) manufactured by Onzo Laboratories. .
また本発明において接触とは、光コネクタ端面に存在する異物が粘着面に付着する程度に接触させればよく、その押し付ける力は適宜選択される。また異物とは、微小粒状等の立体的な異物のみではなく、溶液が蒸発した後に残る平面的な異物を含み、いわゆる「汚れ」を含む。 Further, in the present invention, the term “contact” is sufficient if the foreign substance existing on the end face of the optical connector is brought into contact with the adhesive surface, and the pressing force is appropriately selected. The foreign matters include not only three-dimensional foreign matters such as fine particles but also planar foreign matters remaining after the solution evaporates, and include so-called “dirt”.
次に具体的な手順で本発明の光コネクタ端面の清掃方法を説明する。常法にしたがって、アクリル樹脂製光ファイバをPPS製フェルールに挿通し、単心のSC型コネクタを組み立てる。この後に、研磨紙を用いて光ファイバの端面を研磨する。このように仕上げられた光コネクタの端面に、ゲル状樹脂ブロックを軽く押し付けて接触させる。この動作により、異物はゲル状樹脂ブロックに付着し光コネクタ端面から異物が除去される。この清掃作業の後直ちにコネクタを所定のアダプタに挿入し、コネクタの接続を完了する。 Next, the method for cleaning the end face of the optical connector according to the present invention will be described in a specific procedure. According to a conventional method, an acrylic resin optical fiber is inserted into a PPS ferrule, and a single-core SC connector is assembled. Thereafter, the end face of the optical fiber is polished using polishing paper. The gel-like resin block is lightly pressed and brought into contact with the end face of the optical connector thus finished. By this operation, the foreign matter adheres to the gel-like resin block and the foreign matter is removed from the end face of the optical connector. Immediately after this cleaning operation, the connector is inserted into a predetermined adapter to complete the connection of the connector.
実際に通常の室内に1週間放置された光コネクタ端面を、上記方法により清掃した後に顕微鏡で観察したところ、異物も傷も観察されなかった。 When the optical connector end face which was actually left in a normal room for one week was observed with a microscope after being cleaned by the above method, no foreign matter or scratches were observed.
本発明の光コネクタ端面の清掃方法は、光コネクタ端面に傷をつけることなく清掃が行え、光ファイバの接続作業における作業性を高め、接続損失の抑制に効果がある。この清掃方法は、光コネクタの着脱の都度行うと、接続損失の増加が抑制できて好ましい。 The cleaning method for the end face of the optical connector of the present invention can perform cleaning without damaging the end face of the optical connector, improves the workability in the optical fiber connection work, and is effective in suppressing connection loss. This cleaning method is preferably performed each time the optical connector is attached / detached because an increase in connection loss can be suppressed.
