Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an optical frame for branching or connecting a plurality of optical fibers to another optical fiber.

[0002]

2. Description of the Related Art FIG. 6 shows an example of an optical frame conventionally used. In this figure, the optical frame includes a connection unit 2 and a reserved optical fiber terminal connection section 3 inside a frame main body 1. Although not shown, the optical jumper unit is generally installed on a frame prepared separately from the frame body 1. Further, as the connection unit 2, typically, an optical component storage unit that stores an optical component such as an optical coupler can be exemplified. A large number of the connection units 2 are prepared so as to correspond to a large number of optical fibers 4 described later.

[0003] The optical fiber 4 is introduced into the inside of the frame at an introduction portion 1a of the frame main body 1, and as shown in the figure, is performed as an optical cable 5 in which a number of optical fibers 4 are bundled. Then, a large number of optical fibers 4 (for example, about 1000) are drawn out per optical cable 5 inside the frame main body 1. These optical fibers 4 are connected to the frame body 1
It is bent and drawn into the connection unit 2 using the bending maintaining body 6 and the like provided therein. In the figure, the large number of optical fibers 4 are simplified and shown as one solid line.

[0004] Incidentally, the above-mentioned many optical fibers 4 generally include an optical fiber 4a in a holding state (hereinafter referred to as a holding optical fiber) not connected to any terminal and an optical fiber in a connector connecting state to the connection unit 2 (hereinafter referred to as an already connected state). 4b). Of these, the already connected optical fiber 4b is connected to another optical fiber by being connected to the connection unit 2. On the other hand, the retaining optical fiber 4 a is configured such that an optical connector (optical connector plug) provided at the tip thereof is connected to the retaining optical fiber connection terminal 3. The main purpose of this is to protect the optical connector provided at the distal end of the reserved optical fiber 4a in case that it is desired to use the reserved optical fiber as an already connected optical fiber.

[0005]

However, in the optical frame having such a structure, the holding optical fiber 4a and the connected optical fiber 4b are arranged in such a manner that they pass through the same path in the frame body 1. As a result, there has been a problem that the two are always in a state of being easily entangled, and from this, there is a problem that it is inevitably difficult to distinguish between the two.

As described above, the operation of jumping the already connected optical fiber 4b and the operation of connecting the reserved optical fiber 4a to the optical connector of the connection unit 2 are extremely time-consuming. Further, in the above-mentioned conventional optical frame, there is a problem that workability is further deteriorated when an attempt is made to increase the number of corresponding cores by increasing the density of the optical fibers 4a and 4b.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances. It is an object of the present invention to divide wiring of a large number of optical fibers and to be troubled by entanglement between optical fibers even if the number of corresponding fibers increases. An object of the present invention is to provide an optical frame capable of efficiently performing a jumping operation or the like without using the same.

[0008]

The present invention employs the following means in order to solve the above-mentioned problems. That is, the optical frame according to claim 1 is an optical frame for branching or connecting a plurality of optical fibers to another optical fiber. A connection section housing section for housing a connection section in which another optical fiber is connected to the optical fiber drawn from the fiber drawing section, and a light to which an optical fiber drawn into the connection section storage section from the optical fiber drawing section is wired. An openable and closable door that covers the fiber wiring section from the outside, wherein a part of the optical fiber drawn out from the optical fiber drawout section is pulled into the door and is retained so as to be able to be taken out. Things.

According to this, in short, it can be said that a part of the optical fiber drawn from the optical fiber drawer is attached to the door.
As a result, the optical fiber attached to the door is clearly distinguished from the optical fiber that is also directed from the optical fiber lead-out portion to the connection portion storage portion. In addition, the door here is an openable and closable door that covers the optical fiber wiring section drawn into the connection section housing section from the optical fiber draw-out section from the outside. When the door is opened, the optical fiber wiring section is opened. And a space formed between the door and the door separated therefrom is used as a work space for performing a jumping operation of an optical fiber, a transfer operation of an optical fiber between the optical fiber wiring portion and the door, and the like. It becomes possible. The connection portion in the connection portion storage portion is a connector connection portion between optical fibers,
Various types such as a fusion splicing part can be adopted. In addition, the fact that the optical fiber attached to the door is "retained" means that the optical fiber provided on the door other than simply holding (holding) the optical fiber on the door by a tape, a connector holding unit, or the like, for example. Connecting to is also included. That is, it also includes providing an optical connector on the door and connecting the optical fibers to each other.

[0010] The optical frame according to the second aspect is the first aspect of the invention.
In the above, the connection portion storage portion is a termination portion in which a plurality of optical connectors each of which is capable of connecting an optical fiber to a connector can be stored, and from the optical fiber lead-out portion, a connector is provided to the optical connector of the termination portion. A plurality of optical fibers terminated so as to be connectable are drawn out, and the door is provided with a holding section for holding an optical connector at an end of the optical fiber which is not connected to anywhere.

According to the present invention, an optical connector (optical connector plug) is provided at the tip of the optical fiber pulled out from the optical fiber pull-out portion, and a part of the optical fiber is connected to the terminal at the end. . On the other hand, the optical fiber that is not connected to any part of the optical fiber is held toward a door and held in a holding section provided in the door. That is, this optical fiber may be considered to indicate the holding optical fiber described in the conventional example. Further, in this case, the optical fiber connected to the connector at the above-mentioned termination is referred to as “connected optical fiber” in terms used in the conventional example.
It turns out that. Thus, in the present invention, it is possible to strictly distinguish the reserved optical fiber from the other optical fiber in terms of arrangement.

[0012]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1A is a front view showing an outline of a frame for light according to the present invention, and FIG.
Fig. 3 is a view taken along the line XX in Fig. 1 (a). FIG. 2A is a rear view, and FIG.
FIG. 3A is a view taken along the line YY in FIG. 1B and 2B, the holding terminal board 12
Illustrations such as (described later) and the like are omitted. In the drawings referred to in the following description, the same reference numerals are given to the objects that are not different from the configuration of the conventional example, and the description will be made using the same reference numerals.

In FIG. 1 and FIG. 2, a frame for light includes a connection unit (terminated end) 2, an optical jumper unit 10, an optical fiber alignment tool 11, and a retaining terminal board (door) 12 in a frame body 100. It is provided with. The frame body 100 is
For example, a connection frame 102 provided with multi-stage unit storage shelves 101 for storing a plurality of the connection units 2 in the form of a thin external case vertically and horizontally, an optical jumper unit 10 and an optical fiber alignment tool 11 are stored. And a jumper frame 103 to be mounted.

The optical fiber alignment tool 11 and the jumper unit 10 are both thin in appearance as shown in FIG. As shown in FIGS. 1A and 1B, the jumper unit 10 and the optical fiber alignment tool 11 are horizontally supported by a support (not shown) by a jumper frame 103, and are vertically (FIG. a), (b) middle and upper). However, basically, the optical jumper unit 10
And the optical fiber alignment tool 11 form a one-to-one pair, and the number of layers of the two is the same. The overall configuration of the optical jumper unit 10 and the optical fiber alignment device 11 thus stacked corresponds to an “optical fiber lead-out section” according to the terminology of the present invention.

A large number of optical fibers 4 pulled out from the terminal of the optical cable 5a introduced into the jumper frame 103
d is drawn into the target connection unit 2 from the rear side of the connection frame 102 (see FIGS. 2A and 2B). As shown in FIG. 2 (b), each of these connection units 2 is provided with an optical connector adapter 2a which terminates the end of the optical fiber so that a connector can be connected thereto. In addition, the optical fiber 4d passes through a bending maintaining body 6 or the like that appropriately handles slack or the like before reaching the connection unit 2.

On the other hand, similarly to the optical cable 5a, the optical fiber 4c drawn from the terminal of the optical cable 5b introduced into the jumper frame 103 is connected to the optical jumper unit 10 from the back side of the jumper frame 102. In FIG. 3, the optical fiber 4c is terminated by an optical connector 4e and connected to the optical connector adapter 10a of the optical jumper unit 10. In the case without the connector termination, the optical fiber on the optical jumper unit 10 side is used. 4 by fusion connection. Incidentally, such a connection form is also applicable to the connection unit 2 described above.

The optical fiber 4 drawn out of the optical jumper unit 10 is drawn out to the front side of the jumper frame 103 via the optical fiber alignment tool 11, and is drawn into the connection unit 2 of the connection frame 102 therefrom. (Optical fiber 4b) and those drawn into the holding terminal board 12 (optical fiber 4a). In the connection unit 2, the optical fibers are switchably connected to each other via an optical connector.

In FIG. 3, an optical connector adapter 10a is provided on the side of the optical jumper unit 10 alone. The optical fiber 4c connected to the optical connector adapter 10a from the outside is the optical fiber 4c drawn from the optical cable 5b introduced into the frame body 100 as described above. The optical fiber 4 introduced from the introduction section 10c inside the unit 10 is connected to the optical connector adapter 10a via the optical splitter 10b. That is, the optical fiber 4c connected from the outside of the optical connector adapter 10a is branched and connected so as to form an appropriate number of the plurality of optical fibers 4. In the present invention, the number of line branches is not particularly limited, and it is needless to say that the number of line branches can be appropriately changed.

As shown in FIG. 3, the optical fiber alignment tool 11 alone has a wiring through hole 13 through which all the optical fibers 4 coming from the optical jumper unit 10 are bundled and inserted.
a is an optical fiber collecting part 13 which is a portion protruding in the figure.
b, an aligning tool moving unit 13 is provided. The alignment tool moving part 13 has a through-hole 13c for drawing having a central axis substantially perpendicular to the central axis of the wiring through-hole 13a.
13d is provided. Incidentally, as shown by the dotted line in FIG. 3, such an alignment tool moving unit 13 pulls out vertically (in FIG. 5, described later) perpendicular to the direction in which the optical fiber 4 extends. It is possible to move.

The optical fiber 4 passing through the wiring through hole 13a is separated from the optical fiber 4b passing through the drawing through hole 13c and the holding terminal board 1 separately from the optical fiber alignment tool 11.
The holding optical fiber through hole 14 provided in the collecting portion 14 is provided to face the holding optical fiber collecting portion 14 provided in the second side.
The optical fiber 4a passes through the optical fiber 4a. That is, it is necessary to follow a different route from the optical fibers 4a and 4b, and the optical fibers 4a and 4b are arranged in a state of being strictly distinguished. The optical fiber 4a referred to here
Means the holding optical fiber 4a in the present embodiment.

The optical fiber 4b that has passed through the drawing through hole 13c passes through the housing through hole 15a provided in the main body 15 of the optical fiber alignment tool 11. Incidentally, the storage portion through-hole 15a is formed in the optical fiber storage portion 15b provided as a portion protruding from the main body portion 15, and the central axes of the storage portion through-hole 15a and the lead-out through-hole 13c are the same under normal conditions. It is arranged to be on the line. However, when the position of the extraction through-hole 13c changes due to the movement of the alignment tool moving unit 13, the central axis of the extraction through-hole 13c and the storage unit through-hole 15a are on different straight lines. Will be. The storage portion through-hole 15a and the wiring through-hole 13a have a relationship in which their central axes intersect at right angles.

Here, as shown in FIG. 3, the storage portion through hole 15a is surrounded by a side wall 15c except for a surface through which the central axis passes, and a plate-like lid constituting a part of the side wall 15c. By operating 15d as shown by arrow B in the figure, the opening 15e appears.
In other words, the storage portion through-hole 15a is
Is a hole having a U-shaped cross section with one surface provided with the opening 15e. The optical fiber 4 passes through the hole having the U-shaped cross section. If the plate-like lid 15d is opened, a desired optical fiber 4 can be easily selected from the above. The holding optical fiber through-hole 14a has the same configuration as that described here, and has an opening 14b and a plate-like lid 14 as shown in FIG.
c.

In connection with this, the draw-through hole 1
3c has a form in which all surfaces except the surface through which the central axis passes are surrounded by the fixed side wall 13e. In other words, in short, four of the six sides are closed. However, in the side wall 13e corresponding to the upper surface in the drawing, a slit 13f having a width slightly larger than the diameter of the optical fiber 4 is formed obliquely in the direction in which the optical fiber 4 extends. And this slit 13
By using f, selection of a desired optical fiber 4,
It is one that can be taken out. In addition, as the through hole 13 c for drawing, the slit 13 described here is used.
f, but not the above-described storage portion through-hole 15a.
It is good also as a form provided with an opening part like this and a plate-shaped lid.

The optical fiber 4b that has passed through the housing through-hole 15a goes to the connection unit 2, where the optical connector (optical connector plug) provided at the end is connected. On the other hand, the holding optical fiber 4a passing through the holding optical fiber through hole 14a is
Are retained by the holding terminal board 12.

The holding terminal board 12 is a plate-like door (see arrow A in FIG. 3 or FIG. 4) shown on the right side in FIG. )
That is. More specifically, a plurality of aligned connector holding holes (holding portions) 12a are formed and aligned on the inner surface of the door, and the optical connector 7 at the tip of the holding optical fiber 4a is attached to and detached from these connector holding holes 12a. Mounted as possible. In general, a structure that protects the tip of the optical connector 7 or prevents adhesion of dust or the like is adopted as the connector holding hole 12a. However, instead of the connector holding hole 12a, a mode may be provided in which a terminal (holding housing) to be connected to the connector is provided. The extra length of the holding optical fiber 4a is shown in FIG.
(A) Alternatively, as shown in FIG.
a connected to the optical connector 7 and the reserved optical fiber assembly 1
4 and the both ends, the bending process is performed so as to hang down along the surface of the holding terminal board 12. The above-mentioned holding optical fiber collecting section 14 is fixed to the holding terminal board 12 described above or in the vicinity thereof. Therefore, the optical fiber pulled out from the optical fiber aligning tool 11 is shown in FIG. , FIG. 4, and FIG. 5, as indicated by a portion F in FIG. Further, the holding optical fiber 4a may be held in the holding terminal board 12 by any method other than the above.
For example, depending on the case, the optical connector holding means such as the connector holding hole 12a may not be provided at all, and the tape may be simply adhered to the inner surface of the door with a tape.

In FIG. 1A, the draw-out portion 13d and the optical fiber storage portion 15b described with reference to FIG. 3 can be seen. The optical fiber 4b heading toward the connection unit 2 is layered, and the portion of the optical fiber 4b corresponding to the portion after the storage portion through hole 15a and before the connection unit 2 is, as shown in FIG. ,
The bending process is performed in a state of being suspended downward in the frame main body 100. The curved portion corresponds to the “optical fiber wiring portion” 20 in the terms of the present invention. Therefore, the holding terminal board 12 is
It can be seen that the optical fiber wiring portion 20 is attached to the frame main body 100 so as to cover the optical fiber wiring portion 20 from the outside.

The operation and effect of the optical frame having such a configuration will be described below. In particular, the operation of selecting a desired one from the holding optical fibers 4a and connecting it to the terminal of the connection unit 2, ie, the jumping operation The following description focuses on the mode of realizing.

It should be noted that, unlike the conventional optical frame, it is extremely easy to select a desired holding optical fiber 4a from a large number of optical fibers 4 groups. This is because the holding optical fiber 4a connects the optical connector 7 with the connector holding hole 12a on the holding terminal board 12.
And the optical fiber 4b is clearly distinguished from the optical fiber 4b, and the selection can be made only by selecting a desired optical connector 7 from the group of the connector holding holes 12a. It is because of that.
This is apparent from the fact that the conventional example in which the optical fibers 4 are mixed is significantly improved in workability (see FIG. 6).

When the desired optical connector 7 for the reserved optical fiber 4a is selected, it is detached from the reserved terminal board 12, and the operation related to the reserved optical fiber assembly 14 is performed. At this time, the holding optical fiber through hole 14a is
c, the desired holding optical fiber 4
The selection of a is easily performed. That is, the plate-like lid 14c in the closed state may be opened, and the selected holding optical fiber 4a may be pulled out from the opening 14b.

Then, the desired holding optical fiber 4a is drawn toward the wiring through hole 13a from the optical jumper unit 10 side with respect to the wiring through hole 13a. In this manner, up to just before the wiring through-hole 13a,
The state where the optical connector 7 in the desired holding optical fiber 4a is pulled, that is, the so-called plug reset state easily appears.

Subsequently, the holding optical fiber 4a and the optical connector 7 at the tip thereof are oriented in the direction of the drawing through hole 13c, and the holding optical fiber 4a is passed through the slit 13f. A state in which it has also passed through the storage section through hole 15a appears. The latter operation may be performed by opening the plate-like lid 15d of the through-hole 15a, storing the holding optical fiber 4a therein, and closing the optical fiber 4a again. As a result, the holding optical fiber 4a is pulled out of the through-hole 13c and the storage section through-hole 15c.
a through both the through holes. Finally, the optical connector 7 may be connected to a predetermined terminal of the connection unit 2.

The jumper operation for connecting the desired holding optical fiber 4a to the connection unit 2 in this manner starts from the easy selection of the holding optical fiber 4a, and the connection to the connection unit 2 is extremely simple. And will be realized reliably. Of course, the holding optical fiber 4a
At the time of selection, the work of attaching and detaching the optical connector 7 to and from the holding terminal board 12 is extremely easily performed.

The optical frame according to the present invention is not directly involved in the jumping operation itself, but the extra length of the retaining optical fiber 4a, as described above, is Since the optical fiber alignment tool 11 and the like are simply bent in a state in which the optical fiber alignment tool 11 and the like are hung down toward the front side, the extra length portion also has an advantage that appropriate processing is performed without increasing the size of the optical fiber alignment tool 11 and the like. ing.

Further, the frame for light according to the present invention is constructed such that the holding terminal board 12, that is, the
A space P formed between the optical fiber wiring section 20 in FIG.
Can be used as a whole work space. For example, although not described above, when the optical fiber 4b is replaced with another terminal in the connection unit 2 (this is also a kind of jumping work), mainly the through-hole 13c for extraction and the through-hole of the storage unit are used. The work around the hole 15a is mainly performed. At this time, when the holding terminal board 12 is open, as shown in the space P in FIG. 4, the operation can be performed with a sufficient margin in a sufficiently large space. Also, in this case, the optical fiber alignment tool 11
If the work is carried out in a state where the aligner moving part 13 is pulled out “to the front side” as described with reference to FIG. 3, the work of selecting the optical fiber 4b and the like can be performed in the space P. Workability can be improved. FIG. 5 is a perspective view of a plurality of optical fiber alignment tools 11 in which the alignment tool moving portion 13 of one of the alignment tools 11, that is, the draw-out through hole 13c is pulled out "to the front". Things.

Further, in the present embodiment, the following effects can be pointed out regardless of the effect that the jumping operation of the holding optical fiber 4a and the optical fiber 4b can be easily performed. That is, the optical fiber alignment tool 11
However, it is possible to increase the number of optical jumper units by 10 units. For example, if one unit of the optical jumper unit 10 is added now, it is possible to add the single unit of the optical fiber alignment tool 11 accordingly, and without complicating the optical fiber 4, while maintaining an organized state, It is possible to build a frame for light.

In the present embodiment, what can be indicated by the terms introduced as "optical fiber", "optical connector", and "connection unit" is not intended to limit the present invention. That is, as the optical fiber, for example, a multi-core optical fiber core, an optical cord, or the like can be adopted. As for optical connectors, SC type optical connectors (Single fiber Coupling) specified in JIS C 5973
optical fiber connector), MT type optical connector (Mecanically Transferable) specified in JIS C 5981, JIS
MPO type optical connector (Multifiber P
ush On) can be adopted. Further, as the connection unit, for example, an optical component storage unit such as a coupler unit having a built-in optical coupler or the like, a termination unit in which a plurality of connector ends of an optical fiber are arranged, and the like can be applied.

[0037]

As described above, in the optical frame according to the first aspect, a part of the optical fiber drawn from the optical fiber drawer is attached to the door, and the optical fiber drawer is also drawn from the optical fiber drawer. Due to the presence of the optical fiber toward the connecting portion housing, the arrangement of the two optical fibers can be clearly distinguished. Therefore, a situation in which these two optical fibers are entangled does not occur. Further, since the door here is an openable and closable door that covers the optical fiber wiring section drawn into the connection section storage section from the optical fiber drawout section, when the door is opened, The space formed between the door and the optical fiber wiring section can be used as a work space.

In the optical frame according to the second aspect, an optical connector is provided at an end of the optical fiber pulled out from the optical fiber drawer, and a part of the optical fiber is connected to the terminal at the end. It becomes an already connected optical fiber. On the other hand, those optical fibers that are not connected anywhere,
That is, the holding optical fiber is held in the holding section provided in the door. Therefore, according to the present invention, the already connected optical fiber and the reserved optical fiber can be arranged with strict distinction. This also makes it possible to easily carry out a jumping operation, for example, to make the holding optical fiber an already connected optical fiber.
