【従来の技術】 BACKGROUND OF THE INVENTION
図4を参照するに、従来、多数の光ファイバをシースした多心光ケーブル101が敷設される際に、上記の多心光ケーブル101の多数の光ファイバが局にある光ファイバ集線装置としての光配線盤(MDF: Main Distribution Frame、以下「MDF」と略す)などにおいて光コネクタなどで結線されている。 Referring to FIG. 4, a conventional, multiple in multiple-core optical cable 101 to optical fiber sheath is laid, the optical wiring serving as an optical fiber line concentrator in the number of optical fibers stations of the multi-core optical cable 101 board (MDF: Main Distribution Frame, hereinafter referred to as "MDF") are wired in such an optical connector in such. 上記の多心光ケーブル101は長さが限られているために他の多心光ケーブル101が接続されて延長される。 The above multi-fiber optical cable 101 is extended by another multi-fiber optical cable 101 is connected to the limited length. 図4では第1〜第4多心光ケーブル101A〜101Dが接続されている。 In Figure 4 the first to fourth multi-fiber optical cable 101A~101D is connected.
【0003】 [0003]
近い将来に、FTTH(Fiber−to−the−Home)に代表される光アクセス網が進展し、光ファイバが各加入者まで普及すると予測されている。 In the near future, an optical access network, which is represented by FTTH (Fiber-to-the-Home) is progress, the optical fiber is expected to spread to each subscriber. 局から各家庭までの距離は、たかだか数kmに過ぎないが、一般的に、日本の大都市部の局の加入者数は数万にも達するので、局において、MDFで成端される加入者系の光ファイバも数万に達すると予測される。 Subscription distance to each home from the station, but only at most a few km, in general, since the number of subscribers Bureau of Japan's metropolitan areas reaches even tens of thousands, at a station, which is terminated at the MDF optical fiber Shah systems are also expected to reach tens of thousands. これを単心(1心)光コネクタで成端するとやはり数万のオーダになる。 This becomes the the order of the single-core (one cardiac) again several tens of thousand when terminating an optical connector. そこで、多心光ファイバテープ心線103などの多心の光ファイバを接続するための多心光コネクタとしての例えばMTコネクタ105(Mechanically Transferable Connector)が採用されることで、光コネクタ数を大幅に減らすことができている。 Therefore, by the multi-core ribbon fiber 103 multi-core, for example MT connector as multi-fiber optical connector for connecting an optical fiber 105, such as (Mechanically Transferable Connector) is employed, significantly optical connector number it is possible to reduce.
【0004】 [0004]
一方、光ファイバ心数が数百から千心以上の多心光ケーブル101も実用化され、局へ引き込まれる光ケーブルの本数を減らすことができている。 On the other hand, the multi-fiber optical cable 101 described above Senkokoro from the optical fibers the number of hundreds is commercialized, are able to reduce the number of optical cables drawn to the station. これらの多心光ケーブル101では、通常、4心あるいは8心の光ファイバテープ心線103が多数収納されており、多心光ケーブル101の片端あるいは両端には、4心あるいは8心の多心光コネクタが製造工場にて取りつけられて出荷されている。 In these multi-fiber optical cable 101, typically 4 hearts or 8-core optical fiber ribbon 103 and is a number stored in the one end or both ends of the multi-fiber optical cable 101, multiple-core optical connectors 4 hearts or 8 Heart There has been shipped attached at the manufacturing plant.
【0005】 [0005]
例えば、1000心の光ケーブルは、8心の光ファイバテープ心線103が125本から成り、その一端には125個の8心MTコネクタ105が取り付けられている。 For example, 1000 Heart of the optical cable is made 8-core optical fiber ribbon 103 125 present, are attached 125 of 8-fiber MT connector 105 at one end thereof. 通常、多心光ケーブル101がその先端(引き込み端)から例えばマンホール107A内に引き込まれ、管路(日本の場合は、通常で内径φ75mm)を通して、次のマンホール107Bまで引き通される際に、スプリングアイという金具が先端に取り付けられる。 Usually, the multi-fiber optical cable 101 is drawn from the tip (pull end) for example in the manhole 107A, (in the case of Japan, an inner diameter of φ75mm in Normal) line through, when pulled through to the next manhole 107B, spring bracket is attached to the tip of the eye. なお、各マンホール107A〜107D内では各クロージャ109A〜109Dの中で多心光ファイバテープ心線103の各光ファイバが接続される。 Note that in each manhole 107A~107D each optical fiber of the multi-core ribbon fiber 103 in each closure 109A~109D is connected.
【0006】 [0006]
ところが、多心光ケーブル101の先端が大きくなると、管路内を引き通すことができないことと、マンホール107A〜107Dの間の距離と多心光ケーブル101の長さとの現場での調整の必要性から、通常は多心光ケーブル101の終端末のみにMTコネクタ105が取り付けられて出荷されている。 However, when the tip of the multi-fiber optical cable 101 increases, and can not be passed through pulling the conduit, the need for adjustments in the field of the length of the distance and the multi-core optical cable 101 between the manhole 107a to 107d, Usually is shipped MT connector 105 is attached only at the end end of the multi-fiber optical cable 101. 例えば、図4において、第2多心光ケーブル101Bは第1マンホール107Aから第2マンホール107Bまでの間に引き通されている。 For example, in FIG. 4, the second multi-fiber optical cable 101B is pulled through between the first manhole 107A to the second manhole 107B. 第1マンホール107Aの第1クロージャ109Aの内部では、多数の多心光ファイバテープ心線103がMTコネクタ105により接続されており、第2マンホール107Bの第2クロージャ109Bの内部では、多数の多心光ファイバテープ心線103が融着接続されている。 Inside the first closure 109A of the first manhole 107A, a number of multi-core ribbon fiber 103 is connected by a MT connector 105, within the second closure 109B of the second manhole 107B, a number of multi-fiber optical fiber ribbon 103 is fusion splicing.
【0007】 [0007]
一方、第3多心光ケーブル101Cは第3マンホール107Cから第2マンホール107Bの方向へ、すなわち第2多心光ケーブル101Bとは逆の方向に引き通されている。 On the other hand, the third multi-fiber optical cable 101C is in the direction of the second manhole 107B from the third manhole 107C, that is, the second multi-fiber optical cable 101B is pulled through in the opposite direction. このように、MTコネクタ105による接続と融着接続とがマンホール107A〜107Dで接続毎に交互に繰り返されている。 Thus, the connection and welding connection by MT connector 105 are alternately repeated every connection manhole 107a to 107d.
【0008】 [0008]
大都市部においては、交通渋滞を招く工事は夜間に短時間のみ許可されるのであるが、工場でMTコネクタ105が多心光ケーブル101に取り付けられて出荷されることにより、現場においては多心光ケーブル101の光ファイバ同士を短時間で接続することが可能である。 In metropolitan areas, although construction lead to traffic congestion is being granted only a short time at night, by the MT connector 105 at the factory it is shipped attached to the multi-fiber optical cable 101, in situ multi-fiber optical cable it is possible to connect in a short time optical fibers 101.
【0009】 [0009]
以上は、新しく多心光ケーブル101が敷設されるときに関するものであるが、敷設されてからある期間経過後に当初の需要予測と異なる事態になった場合、敷設された多心光ケーブル101の多心光ファイバテープ心線103の配線替えをせざるを得ない事態に迫られることがある。 Above, new but multi-fiber optical cable 101 is related to when it is laid, when it becomes laid originally forecast different situation after the passage period of time from the multi-fiber optical multifiber optical cable 101 laid it may be forced to rewiring of the fiber ribbon 103 in forced situation. このような場合は、MTコネクタ105で接続したクロージャ109A,109Cを開き、当該MTコネクタ105が脱着されて新しい需要に見合うように配線替えが行われる。 In such cases, closures 109A connected by MT connector 105, open the 109C, rewiring as the MT connectors 105 meet desorbed by the new demand is made. この時、クロージャ109A,109Cには多数のMTコネクタ105が存在するので、誤脱着や誤接続を避けるために個々のMTコネクタ105を個別に識別する必要がある。 At this time, since the closure 109A, a number of MT connector 105 to 109C is present, it is necessary to identify individually each MT connector 105 in order to avoid false desorption or erroneous connection.
【0010】 [0010]
図5及び図6を参照するに、MTコネクタ105としては、JIS(規格番号JIS C 5981)では、2心、4心、8心、10心、12心光ファイバテープ心線用のフェルール111が規格化されている。 Referring to FIGS. 5 and 6, the MT connector 105, the JIS (Standard No. JIS C 5981), 2 heart, 4 heart, 8 heart, 10 heart 12 heart optical fiber ferrule 111 for ribbons It has been standardized.
