Description

本発明は、光ファイバ通信ネットワークの構築に利用される分配用光カプラモジュールおよびカプラモジュール収容架に関するものである。   The present invention relates to an optical coupler module for distribution and a coupler module housing rack used for construction of an optical fiber communication network.

ＦＴＴＨ（Fiber To The Home）サービスは、光ファイバを使って高速なインターネット接続を実現するサービスである。
ここで１本の光ファイバを１人のユーザーが使用すると、その導入コストが銅線（電話線）と比べて非常に高くなってしまうため、１本の光ファイバを複数のユーザーで共有するＰＯＮ（Passive Optical Network）が広く利用されている。ＰＯＮとは、伝送路を２〜３２本に分岐させるスター型ネットワークのことであり、ＰＯＮには、1つの光信号を２つ以上の出力に分岐し、また、２つ以上の光入力信号を１つの出力に結合する光カプラが用いられる。光カプラは電源が不要であり、しかもメンテナンスフリーであるため、伝送路の複数個所に光カプラを設置することにより、柔軟なネットワークを設計することができる。 The FTTH (Fiber To The Home) service is a service that realizes a high-speed Internet connection using an optical fiber.
Here, if one user uses one optical fiber, the introduction cost becomes very high compared to copper wire (telephone line), so PON shares one optical fiber with multiple users. (Passive Optical Network) is widely used. A PON is a star network that branches a transmission line into 2 to 32 lines. A PON branches one optical signal into two or more outputs, and two or more optical input signals. An optical coupler is used that couples to one output. Since an optical coupler does not require a power source and is maintenance-free, a flexible network can be designed by installing optical couplers at a plurality of locations on the transmission path.

また近年では、ＧＥ−ＰＯＮ（Gigabit Ethernet-Passive Optical Network）と呼ばれる、ギガビットのＦＴＴＨサービスを実現する技術が開発されている。ＧＥ−ＰＯＮは、ＰＯＮ技術にギガビットイーサネット技術（登録商標）を取り込み、１Ｇｂｐｓという超高速で光ファイバ通信を実現する技術である。   In recent years, a technology called GE-PON (Gigabit Ethernet-Passive Optical Network) for realizing a gigabit FTTH service has been developed. GE-PON is technology that incorporates Gigabit Ethernet technology (registered trademark) into PON technology and realizes optical fiber communication at an ultra-high speed of 1 Gbps.

なお伝送装置側の１本の光ファイバとユーザーの端末側の複数の伝送路との間に光カプラを介在させ、この光カプラによって伝送装置側の光ファイバ（局側光ケーブル心線）を分岐して複数のユーザーで共用できるようにした方式は、ＰＤＳ（Passive Double Star）方式と呼ばれる。 FIG. 7 shows a specific example of the GE-PON system.

Between the two, a single WDM (Wavelength Division Multiplexing) system is used in which a wavelength of 1490 nm is assigned in the downstream (center to subscriber direction) and 1310 nm is assigned in the upstream (subscriber to center direction). It communicates while handling like a fiber.
An optical coupler is interposed between one optical fiber on the transmission device side and a plurality of transmission lines on the user terminal side, and the optical fiber on the transmission device side (station side optical cable core) is branched by this optical coupler. A system that can be shared by a plurality of users is called a PDS (Passive Double Star) system.

上述した従来の分配用光カプラモジュールは、複数のアダプタが横方向に並んだ扁平横長形状をしており、局側光ケーブル心線が各分配用光カプラモジュールから延出して錯綜し、ＰＩＦ盤に接続されている。そのため、例えばＰＩＦ盤には異常はないが光信号が通らない場合や、ＰＩＦ盤に不具合があり交換した正常なＰＩＦ盤に局側光ケーブル心線を差し替えてやる場合などに、これにつながれた分配用光カプラモジュールを、局側光ケーブル心線を辿ることで探し当てる作業は煩雑であるとともに、局側光ケーブル心線を辿る作業工程でケーブルの取り違いを起こしやすく、分配用光カプラモジュールの特定を誤認することもあった。   The conventional optical coupler module for distribution described above has a flat horizontally long shape in which a plurality of adapters are arranged in the horizontal direction, and the optical fiber cable on the side of the station extends from each optical coupler module for distribution and is complicated.

The casing 18 is configured to have a vertically long outer shape in which the lateral width is approximately the same as the lateral width of the PIF board 111 and the height is approximately the same as the height of the optical transmission device 12. Each distribution optical coupler module 10 is arranged to face the front side of each PFI board with a certain distance. A screw hole 31 is formed below the front surface of the casing 18 so as to be fixed to an optical coupler module housing 26 described later.

ケーシング１８内には、局側光ケーブル心線１４の一部と、局側光ケーブル心線を複数（図では８本）の加入者側光ケーブル心線１６に分岐する光カプラ２２と、各加入者側光ケーブル心線の末端に加入者側光ケーブル１６ａを接続するための複数のアダプタ（ＳＣ−ＳＣアダプタ２４）が収容されている。ここで複数のＳＣ−ＳＣアダプタ２４は、ケーシング１８の光伝送装置１２と対向する面（背面）に、縦方向に並んで配置されている。また局側光ケーブル心線１４は、ケーシング１８の背面下方位置から外部に延出し、その先端には光伝送装置１２に取り付けたＰＩＦ盤１１１のＳＣアダプタ１１９に接続するためのＳＣコネクタ１２１が設けられている。   In the casing 18, a part of the station side optical cable core 14, an optical coupler 22 for branching the station side optical cable core cables into a plurality (eight in the figure) of the subscriber side optical cable cables 16, and each subscriber side A plurality of adapters (SC-SC adapters 24) for connecting the subscriber side optical cable 16a are accommodated at the end of the optical cable core. Here, the plurality of SC-SC adapters 24 are arranged side by side in the vertical direction on the surface (back surface) of the casing 18 facing the optical transmission device 12. The station side optical cable core 14 extends from the lower position of the back surface of the casing 18 to the outside, and an SC connector 121 for connecting to the SC adapter 119 of the PIF panel 111 attached to the optical transmission device 12 is provided at the tip. ing.

ケーシング１８の底面に導入された局側光ケーブル心線１４は、ケーシング前面の裏面上部に接着固定された分配用光カプラ２２（スプリッタ）に緩やかに湾曲して接続されている。分配用光カプラ２２は、局側光ケーブル心線１４を複数の加入者側光ケーブル心線１６に分岐する。分配用光カプラ２２から分岐した各加入者側光ケーブル心線１６は、ケーシング１８内で一周程度巻回し、その先端に設けられた各ＳＣ−ＳＣアダプタ２４は、上述のようにケーシング１８の背面に縦位置に並ぶようにして取り付けられている。なおＳＣ−ＳＣアダプタ２４には加入者側光ケーブル１６ａの末端のＳＣ−ＳＣコネクタ１２３が接続され、加入者側光ケーブル１６ａは分配用光カプラモジュール１０と光伝送装置１２との間の空間を通り、下方に導かれた後に、外部へと導出される。なお図２では図面を簡略化するために、最上部にある１つのＳＣ−ＳＣアダプタ２４のみにＳＣ−ＳＣコネクタ１２３が接続され、ここから加入者側光ケーブル１６ａが伸びた状態を示している。   The station-side optical cable core 14 introduced into the bottom surface of the casing 18 is gently curved and connected to a distribution optical coupler 22 (splitter) that is bonded and fixed to the upper back of the front surface of the casing. The distribution optical coupler 22 branches the station side optical cable core 14 into a plurality of subscriber side optical cable cores 16. Each subscriber-side optical cable core 16 branched from the distribution optical coupler 22 is wound about one turn in the casing 18, and each SC-SC adapter 24 provided at the tip of the optical fiber core 16 is connected to the back surface of the casing 18 as described above. It is mounted so that it is aligned vertically. The SC-SC adapter 24 is connected to the SC-SC connector 123 at the end of the subscriber-side optical cable 16a. The subscriber-side optical cable 16a passes through the space between the distribution optical coupler module 10 and the optical transmission device 12, After being guided downward, it is led out. 2, in order to simplify the drawing, the SC-SC connector 123 is connected to only one SC-SC adapter 24 at the top, and the subscriber side optical cable 16a is extended therefrom.

このような分配用光カプラモジュール１０は、後述する光カプラモジュール収容架２６の上に複数個載置されて光伝送装置１２の前面側に一定の距離を空けて配置される。   A plurality of such distribution optical coupler modules 10 are placed on an optical coupler module housing 26 described later, and are arranged at a certain distance on the front side of the optical transmission device 12.

本実施例の分配用光カプラモジュール１０によれば、ケーシング１８を縦長の直方体形状に形成するとともに、アダプタを縦方向に並べて配置し、かつ、分配用光カプラモジュール１０内からの局側光ケーブル心線１４の取り出し位置と局側光ケーブル心線１４の光伝送装置１２との接続位置とを対向させることで、分配用光カプラモジュール１０と、これが接続された光伝送装置１２のＰＩＦ盤１１１との対応関係が明確化される。
また、後述する光カプラモジュール収容架２６を用い、ケーシング１８の光伝送装置１２と対向する面にアダプタ２４を縦方向に並べて配置することで、光伝送装置のＰＩＦ盤と分配用カプラモジュールとの接続距離を短くすることができるため、局側光ケーブル心線の取り廻しを簡素化することができる。 According to the distribution optical coupler module 10 of the present embodiment, the casing 18 is formed in a vertically long rectangular parallelepiped shape, the adapters are arranged in the vertical direction, and the local optical cable core from the distribution optical coupler module 10 is arranged. The optical fiber module for distribution 10 and the PIF board 111 of the optical transmission apparatus 12 to which the distribution optical coupler module 10 is connected are made by making the take-out position of the line 14 and the connection position of the optical fiber cable 14 connected to the optical transmission apparatus 12 opposite to each other. Correspondence is clarified.

As a result, the number of SC-SC adapters of the distribution optical coupler module required can be increased, and the number of lines that can be handled by one rack can be increased.

次に本実施例の分配用光カプラモジュール１０を載置して光伝送装置１２に固定するための光カプラモジュール収容架について説明する。図３は本実施例に用いられる光カプラモジュール収容架の分解斜視図である。   Next, an optical coupler module housing rack for mounting the distribution optical coupler module 10 of this embodiment and fixing it to the optical transmission device 12 will be described. FIG. 3 is an exploded perspective view of the optical coupler module housing rack used in this embodiment.

本実施例の光カプラモジュール収容架２６は、縦長の分配用光カプラモジュール１０をその上に載置・固定するためのもので、光伝送装置１２の前面に受け台状に伸長して取り付けられる。光カプラモジュール収容架２６は金属板を折り曲げることで製作され、光伝送装置１２に固定される収容架母体２６ａと、複数の分配用光カプラモジュール１０を載置し、かつ、収容架母体２６ａに対して引き出しのごとく摺動する収容架本体２６ｂとから構成されている。 The optical coupler module housing rack 26 of the present embodiment is for mounting / fixing the vertically distributing optical coupler module 10 thereon, and is attached to the front surface of the optical transmission device 12 so as to extend in the form of a pedestal. . The optical coupler module housing 26 is manufactured by bending a metal plate, and the housing base 26a fixed to the optical transmission device 12 and the plurality of distribution optical coupler modules 10 are placed on the housing base 26a. On the other hand, it is comprised from the accommodation frame main body 26b which slides like a drawer.

収容架母体２６ａは受け台を構成する上側を開口する略コの字型形状をしており、その末端にはフランジ状の脚部３３が形成されている。収容架母体２６ａは、この脚部３３に開口した開孔にネジを差し入れて、これを位置合わせをした光伝送装置１２のフランジ部１２７の開孔およびラックの開孔に螺合することで、光伝送装置１２とともにラックにしっかりと取り付けられる（図1参照）。
また収容架母体２６ａ底面の左右には、次に説明する収容架本体２６ｂをスライドさせて引き出すために、前後方向に平行する縦長穴３５が開口形成されている。さらに収容架母体２６ａの左右に立設する側壁面には、分配用光カプラモジュール１０のＳＣ−ＳＣアダプタ２４に接続した加入者側光ケーブル１６ａを通して下側方向に取り出すための開口３７が形成されている。 The housing base 26a has a substantially U-shape opening on the upper side constituting the cradle, and a flange-like leg portion 33 is formed at the end thereof. The accommodating frame 26a is inserted into the opening opened in the leg portion 33, and screwed into the opening of the flange portion 127 of the optical transmission device 12 and the opening of the rack, which are aligned, Attached to the rack together with the optical transmission device 12 (see FIG. 1).
In addition, on the left and right sides of the bottom surface of the housing base 26a, vertically long holes 35 that are parallel to the front-rear direction are formed in order to slide and pull out the housing base body 26b described below. Further, openings 37 are formed on the side wall surfaces standing on the left and right of the housing base 26a so as to be taken out downward through the subscriber side optical cable 16a connected to the SC-SC adapter 24 of the distribution optical coupler module 10. Yes.

一方収容架本体２６ｂは、収容架母体２６ａの底面の上面に接する収容架本体２６ｂ底面と、この面の前方において立設する前壁面から形成されており、収容架本体２６ｂ底面には収容架母体２６ａの各縦長穴に対応する位置にボルトを通すためのボルト穴３９が各２箇所形成されている。
また収容架本体２６ｂの前壁面には、前述した分配用光カプラモジュール１０のケーシング１８前面下方のネジ穴３１に対応する高さに、水平方向に細長い横長穴４１が開口形成されている。 On the other hand, the storage rack main body 26b is formed of a bottom surface of the storage rack main body 26b in contact with the upper surface of the bottom surface of the storage rack base 26a and a front wall surface standing in front of this surface. Two bolt holes 39 for passing bolts are formed at positions corresponding to the respective longitudinal elongated holes 26a.
Further, a horizontally elongated horizontal hole 41 is formed in the front wall surface of the housing body 26b at a height corresponding to the screw hole 31 below the front surface of the casing 18 of the distribution optical coupler module 10 described above.

収容架本体２６ｂは、光伝送装置１２に取り付けられた収容架母体２６ａの上に重なるように置かれ、左右各２箇所のボルト穴３９に挿入したボルトを、収容架母体２６ａの縦長穴３５に通し、これを下側からナットで固定することで収容架母体２６ａに固定される。また各ナットを若干緩め、収容架本体２６ｂを引っ張ることで、収容架本体２６ｂを収容架母体２６ａに対して摺動させて引き出すことができる。これにより、必要に応じて光伝送装置１２と分配用光カプラモジュール１０との間の空間を広げることができ、保守・点検時等において、その作業性を向上させることができる。なおこの場合、ケーシング１８から光伝送装置１２に伸びる局側光ケーブル心線１４には、予め収容架本体２６ｂの引き出しを許容するためのゆとりを持たせておく必要がある。   The receiving rack body 26b is placed so as to overlap the receiving rack base 26a attached to the optical transmission device 12, and the bolts inserted into the bolt holes 39 at the two left and right positions are inserted into the vertically elongated holes 35 of the receiving rack base 26a. Then, it is fixed to the housing frame 26a by fixing it with a nut from below. In addition, by slightly loosening each nut and pulling the accommodation rack body 26b, the accommodation rack body 26b can be slid with respect to the accommodation rack base body 26a. As a result, the space between the optical transmission device 12 and the distribution optical coupler module 10 can be expanded as necessary, and the workability can be improved during maintenance and inspection. In this case, the station-side optical cable core 14 extending from the casing 18 to the optical transmission device 12 needs to have a margin for allowing the accommodation rack body 26b to be pulled out in advance.

収容架本体２６ｂの前壁面には横長穴４１が形成されており、これと分配用光カプラモジュール１０のケーシング１８前面下方のネジ穴３１およびこのネジ穴に螺合するネジは、スライド機構を構成する。このスライド機構は、前方から横長穴４１に通したネジを、収容架本体２６ｂに載置した分配用光カプラモジュール１０のネジ穴３１に螺合することで、分配用光カプラモジュール１０を収容架本体２６ｂに固定する一方、このネジを若干緩めることで分配用光カプラモジュール１０の収容架本体２６ｂ上での横方向へのスライド移動を許容する。
このスライド機構により分配用光カプラモジュール１０は、光カプラモジュール収容架２６に載置後に、局側光ケーブル心線１４の光伝送装置１２との接続位置とが対向するように容易に位置合わせをすることができる。 A horizontally long hole 41 is formed in the front wall surface of the housing body 26b. The screw hole 31 below the front surface of the casing 18 of the distribution optical coupler module 10 and the screw screwed into the screw hole constitute a slide mechanism. To do. The slide mechanism is configured to screw the distribution optical coupler module 10 into the accommodation rack by screwing screws passed through the oblong holes 41 from the front into the screw holes 31 of the distribution optical coupler module 10 placed on the accommodation rack body 26b. While being fixed to the main body 26b, this sliding screw is loosened slightly to allow the distribution optical coupler module 10 to slide in the lateral direction on the housing main body 26b.
With this slide mechanism, the distribution optical coupler module 10 is easily aligned after being placed on the optical coupler module housing 26 so that the connection position of the station side optical cable core 14 and the optical transmission device 12 faces each other. be able to.

図４は実施例２に用いられる分配用光カプラモジュールを底面側から見た斜視図、図５は実施例２に用いられる光カプラモジュール収容架の斜視図、図６は光カプラモジュール収容架上に載置した分配用光カプラモジュールを転倒させた状態を示した断面図である。
なお本実施例において実施例１と同様の構成については、実施例１で用いた符号と同様の符号を付し、重複する説明を省略する。 4 is a perspective view of the distribution optical coupler module used in the second embodiment as viewed from the bottom side, FIG. 5 is a perspective view of the optical coupler module housing rack used in the second embodiment, and FIG. 6 is a view on the optical coupler module housing rack. It is sectional drawing which showed the state which fell the optical coupler module for distribution mounted in (2).
In addition, about the structure similar to Example 1 in a present Example, the code | symbol similar to the code | symbol used in Example 1 is attached | subjected, and the overlapping description is abbreviate | omitted.

図４に示したように本実施例の分配用光カプラモジュール１０は、実施例１の分配用光カプラモジュールとほぼ同様の構成を有しているが、ケーシング１８の底面には、外部に取り出した局側光ケーブル心線１４の通行を許容する開口部２８が形成されている。   As shown in FIG. 4, the distribution optical coupler module 10 of the present embodiment has substantially the same configuration as that of the distribution optical coupler module of the first embodiment. An opening 28 that allows passage of the local optical fiber 14 is formed.

一方図５に示した光カプラモジュール収容架２６は、分配用光カプラモジュール１０を載置する収容架母体２６ａと、収容架母体２６ａの先端部に蝶番４３により転倒自在に連結された転倒体２６ｃとからなる。この蝶番および転倒体２６ｃは転倒機構を構成する。
収容架母体２６ａは光伝送装置１２の前面に受け台状に伸長して取り付けられる上側を開口する略コの字型形状をした板材であり、その末端にはフランジ状の脚部３３が形成されていることは実施例１の収容架母体と同様である。また、収容架母体２６ａの底面の左右に立設する側壁面の前方側には、次に説明する転倒体２６ｃの転倒を防止するための転倒防止穴４５が形成されている。
転倒体２６ｃは収容架母体２６ａの先端に蝶番４３を介して接続され、また、その左右両端には直角に折り曲げられた屈曲部４７を有している。この屈曲部には収容母体の左右の側壁面の転倒防止穴４５に螺合したネジを貫通させる１／３円弧状の円弧長穴４９が形成されている。また転倒体２６ｃには、実施例1と同様に、分配用光カプラモジュール１０のケーシング１８前面下方のネジ穴に対応する高さに、水平方向に細長い横長穴４１が開口形成されている。 On the other hand, the optical coupler module housing rack 26 shown in FIG. 5 has a housing base body 26a on which the distribution optical coupler module 10 is placed, and a fall body 26c that is connected to the tip of the housing base body 26a by a hinge 43 so as to be freely turned over. It consists of. The hinge and the fall body 26c constitute a fall mechanism.
The housing base 26a is a plate material having a substantially U-shape that opens on the front surface of the optical transmission device 12 and is attached in a cradle shape. A flange-like leg 33 is formed at the end of the housing base 26a. This is the same as the housing frame of the first embodiment. Further, on the front side of the side wall surface standing on the left and right of the bottom surface of the housing base 26a, a fall prevention hole 45 for preventing the fall of the fall body 26c described below is formed.
The overturning body 26c is connected to the tip of the housing base 26a via a hinge 43, and has bent portions 47 that are bent at right angles at both left and right ends thereof. In this bent portion, a 1/3 arc-shaped arc long hole 49 is formed through which a screw screwed into the fall prevention hole 45 on the left and right side wall surfaces of the housing base is passed. Similarly to the first embodiment, a horizontally elongated long hole 41 is formed in the falling body 26c at a height corresponding to a screw hole below the front surface of the casing 18 of the distribution optical coupler module 10.

上記の分配用光カプラモジュール１０は、転倒体２６ｃを収容架母体２６ａに対して立設させた状態で、分配用光カプラモジュール１０のケーシング１８前面下方のネジ穴３１に、転倒体２６ｃの横長穴４１を通してネジを螺合することで、光カプラモジュール収容架２６に固定される。このとき、収容架母体２６ａの左右側壁面の転倒防止穴４５と転倒体２６ｃの屈曲部４７に形成された円弧長穴４９にはボルト／ナットが貫通して両者を固定し、転倒体２６ｃの転倒を防止している。
一方、保守点検時等には転倒防止穴と円弧長穴を貫通するボルト／ナットを若干緩めることで、転倒体２６ｃの前面側への転倒、すなわち転倒体２６ｃに固定した分配用光カプラモジュール１０の前面側への転倒が可能となる。このとき、分配用光カプラモジュール１０のケーシング１８背面の最下部から外部に延出して光伝送装置１２のＰＩＦ盤１１１に接続される局側光ケーブル心線１４は、図６に示したように、ケーシング１８の底面に形成された開口部２８を通行するため、分配用光カプラモジュール１０の転倒によって局側光ケーブル心線１４が大きく屈曲することなく、逆にケーシング１８内での屈曲が解消されることとなる。
なお転倒体２６ｃの屈曲部の円弧長穴４９は、転倒体２６ｃが収容架母体２６ａの底面と面一となる角度までのみ、転倒体２６ｃの転倒を許容するようになっている（保持機構）。 In the distribution optical coupler module 10 described above, with the falling body 26c erected with respect to the housing base 26a, the horizontal direction of the falling body 26c is inserted into the screw hole 31 below the front surface of the casing 18 of the distribution optical coupler module 10. By screwing a screw through the hole 41, the screw is fixed to the optical coupler module housing rack 26. At this time, the bolt / nut penetrates and fixes both of the fall prevention hole 45 on the left and right side wall surfaces of the housing base 26a and the circular arc hole 49 formed in the bent portion 47 of the fall body 26c. Prevents falling.
On the other hand, at the time of maintenance inspection, etc., the bolt / nut passing through the fall prevention hole and the circular arc hole is slightly loosened, so that the fall body 26c falls to the front side, that is, the distribution optical coupler module 10 fixed to the fall body 26c. Can fall to the front side. At this time, as shown in FIG. 6, the station-side optical cable core 14 that extends outward from the lowermost portion of the back surface of the casing 18 of the distribution optical coupler module 10 and is connected to the PIF panel 111 of the optical transmission device 12 Since the opening 28 formed on the bottom surface of the casing 18 passes, the local optical cable core 14 is not greatly bent by the overturn of the distribution optical coupler module 10, and the bending in the casing 18 is eliminated conversely. It will be.
Note that the circular arc hole 49 in the bent portion of the fall body 26c allows the fall body 26c to fall only to an angle where the fall body 26c is flush with the bottom surface of the housing base 26a (holding mechanism). .

本実施例によれば、必要に応じて分配用光カプラモジュールを取り付けた転倒体を前面側に転倒させることができる。そのため保守・点検時等において、分配用光カプラモジュールの背面を簡易に上向きにすることができ、また、光伝送装置と分配用光カプラモジュールとの間の空間も広くすることができるため、その作業性も向上することとなる。   According to the present embodiment, the overturned body to which the distribution optical coupler module is attached can be turned over to the front side as necessary. Therefore, during maintenance and inspection, the back of the distribution optical coupler module can be easily turned upward, and the space between the optical transmission device and the distribution optical coupler module can be widened. Workability will also be improved.
