Abstract

A termination unit includes: a plurality of first optical fibers fusion-connected to a multicore cable; a tray slidable in a first direction, the tray being provided on one end side of the termination unit in the first direction; and a plurality of adapters which are provided in a line on the tray, to which a plurality of second optical fibers are connected from each of one end sides of the adapters, and to which the plurality of first optical fibers are connected from each of the other end sides of the adapters, in which the tray has a cover part for protecting the plurality of adapters, and in which the cover part is rotatable with a shaft that extends along a second direction, and the cover part rotates downward when the tray has slid in a direction toward the one end side from the other end side.

First claim

The invention claimed is:

1. A termination unit located in a rack part of an optical fiber rack, comprising:
a plurality of first optical fibers fusion-connected to a multicore cable introduced from an outside of the optical fiber rack;
a tray slidable in a first direction, the tray being provided on one end side of the termination unit in the first direction; and
a plurality of adapters which are arranged in a line on the tray, to which a plurality of second optical fibers are connected from each of one end sides of the plurality of adapters, and to which the plurality of first optical fibers are connected from each of the other end sides of the plurality of adapters,
wherein the tray includes a cover part configured to protect the one end side of the plurality of adapters, and the tray includes a support part configured to lock and support the cover part, the support part being provided side by side with the cover part in a second direction intersecting the first direction, and
wherein the cover part is rotatable with a shaft that extends along the second direction as a supporting shaft, and the cover part is configured to rotate downward when the tray has slid in a direction toward the one end side from the other end side.

2. The termination unit according to claim 1 ,
wherein the support part has a fan shape in a plan view.

3. The termination unit according to claim 1 ,
wherein the support part includes a guide configured to guide the plurality of second optical fibers toward the first direction, and
wherein the guide is located along an outer edge of the support part.

4. The termination unit according to claim 3 ,
wherein the guide includes a part extending in a direction of approaching the tray.

5. The termination unit according to claim 4 ,
wherein an inclined angle from the first direction of the part is 5° to 30°.

6. The termination unit according to claim 1 ,
wherein the one end side of the termination unit corresponds to a front end side of the termination unit.

7. A termination unit located in a rack part of an optical fiber rack, comprising:
a first optical fiber fusion-connected to a multicore cable extending toward an outside of the optical fiber rack;
a tray slidable in a first direction, the tray being provided on a front end side of the termination unit; and
an adapter on the tray and in the termination unit, the adapter including a first end and a second end opposed to each other in the first direction,
wherein the first end is connected to a second optical fiber and the second end is connected to the first optical fiber,
wherein the tray includes a cover configured to protect the first end of the adapter,
wherein the cover part is rotatable with a shaft that extends along a second direction intersecting the first direction as a supporting shaft, and the cover part is configured to rotate downward when the tray has slid toward the front end side in the first direction, and
wherein the tray includes a supporter configured to lock and support the cover, the supporter being provided side by side with the cover in the second direction.

8. The termination unit according to claim 7 ,
wherein the supporter has a fan shape in a plan view.

9. The termination unit according to claim 7 ,
wherein the supporter includes a guide configured to guide the second optical fiber toward the first direction, and
wherein the guide is located along an outer edge of the supporter.

10. The termination unit according to claim 9 ,
wherein the guide includes a part extending in a direction of approaching the tray.

11. The termination unit according to claim 10 ,
wherein an inclined angle from the first direction of the part is 5° to 30°.
