Abstract

An optical fiber rack includes a rack part on which a plurality of termination units arranged in a vertical direction are located, a first optical fiber housing part in which extra length wiring parts of a plurality of first optical fibers connected with each of the plurality of termination units are housed, a second optical fiber housing part in which an extra length wiring part of a second optical fiber connected with any of the termination units is housed, and a partition plate partitioning the first optical fiber housing part from the second optical fiber housing part.

Claims

1. An optical fiber rack comprising:

a rack part on which a plurality of termination units arranged in a vertical direction are located;

a first optical fiber housing part in which extra length wiring parts of a plurality of first optical fibers connected with each of the plurality of termination units are housed;

a second optical fiber housing part in which an extra length wiring part of a second optical fiber connected with any of the plurality of termination units is housed;

a partition plate partitioning the first optical fiber housing part from the second optical fiber housing part;

a plurality of rails positioned on an opposite side of the first optical fiber housing part with respect to the partition plate and provided apart from the partition plate, the second optical fiber being laid on the rails; and

a first cable housing part provided on an opposite side of the first optical fiber housing part with respect to the termination units,

wherein the rack part and the first optical fiber housing part are next to each other,

wherein the termination unit is connected with any of a first input optical fiber laid on an opposite side of the first optical fiber housing part with respect to the rack part or a second input optical fiber laid between the partition plate and the plurality of rails,

wherein the extra length wiring parts of the first optical fibers, the extra length wiring part of the second optical fiber, the first input optical fiber, and the second input optical fiber are arranged so as to not be in contact with each other,

wherein the first input optical fiber is housed in the first cable housing part,

wherein each of the rails further includes a first part and a second part separated from each other,

wherein an opening is provided between the first part and the second part in an extending direction of the rails, and is provided on a back side of the first optical fiber housing part with respect to the partition plate,

wherein each of the first part and the second includes a downward curved portion, and

wherein the downward curved portion of the first part faces the downward curved portion of the second part through the opening.

2. The optical fiber rack according to claim 1,

wherein a fusion optical fiber is provided within at least one of the termination units, and

wherein the termination unit includes a fusion tray configured to house, a portion where the fusion optical fiber is fused to the second input optical fiber.

3. The optical fiber rack according to claim 1,

wherein each of the plurality of rails includes a main part and a disconnect part disconnecting a part of the main part, and

wherein the disconnect part is provided on an back side of the first optical fiber housing part with respect to the partition plate.

4. The optical fiber rack according to claim 3, wherein a part of the main part forming the disconnect part is curved downward.

5. The optical fiber rack according to claim 3, further comprising a tray provided between the disconnect part of the rail located at a lowermost side in the vertical direction among the plurality of rails and a bottom frame part of the rack part, the extra length wiring part of the second optical fiber being put on the tray.

6. The optical fiber rack according to claim 1,

wherein one and the other ends of each of the rails have shapes capable of being coupled with each other.

7. The optical fiber rack according to claim 1, further comprising:

a second cable housing part provided between the partition plate and the rails,

wherein the second input optical fiber is housed in the second cable housing part.

8. The optical fiber rack according to claim 1,

wherein the extra length part of the second optical fiber is provided in the opening.

9. The optical fiber rack according to claim 1,

wherein the first optical fiber housing part, the first cable housing part and the termination units are located on a front side of the second optical fiber housing part with respect to the partition plate.
