Abstract

An optical connector includes a holder configured to hold at least three or more optical connector plugs. The optical connector plugs and the adapters are arranged in an intersecting direction intersecting with a connecting direction. The optical connector plugs include a first optical connector plug and a second optical connector plug. Any of the first optical connector plug and the adapter to which the first optical connector plug is connected has a latch mechanism configured to engage the first optical connector plug with the adapter. Any of the second optical connector plug and the adapter to which the second optical connector plug is connected does not have a latch mechanism configured to engage the second optical connector plug with the adapter.

Claims (38)

1. An optical connector comprising at least three or more optical connector plugs collectively connected to a plurality of adapters along a connecting direction, wherein

the optical connector includes a holder configured to hold the at least three or more optical connector plugs,

the optical connector plugs and the adapters are arranged in an intersecting direction intersecting with the connecting direction,

the optical connector plugs include a first optical connector plug and a second optical connector plug,

any of the first optical connector plug and the adapter to which the first optical connector plug is connected has a latch mechanism configured to engage the first optical connector plug with the adapter, and

any of the second optical connector plug and the adapter to which the second optical connector plug is connected does not have a latch mechanism configured to engage the second optical connector plug with the adapter, wherein

both of the first optical connector plug and the second optical connector plug have an optical fiber and a ferrule configured to hold the optical fiber, and

an end portion of the ferrule of the second optical connector plug is located on the adapter side beyond an end portion of the ferrule of the first optical connector plug.

2. The optical connector according to claim 1 , wherein

the second optical connector plugs are individually disposed on both end sides in the intersecting direction, and

the first optical connector plugs are disposed between a plurality of the second optical connector plugs.

3. The optical connector according to claim 1 , wherein

the second optical connector plug protrudes on the adapter side beyond the first optical connector plug.

4. The optical connector according to claim 1 , comprising

a grip part configured to grip the holder.

5. The optical connector according to claim 1 , comprising

at least one or more connector plug groups having six optical connector plugs arranged in the intersecting direction.

6. An optical connector comprising at least three or more optical connector plugs collectively connected to a plurality of adapters along a connecting direction, wherein

the optical connector includes a holder configured to hold the at least three or more optical connector plugs,

the optical connector plugs and the adapters are arranged in an intersecting direction intersecting with the connecting direction,

the optical connector plugs include a first optical connector plug and a second optical connector plug,

the holder including a plurality of plug holding parts, wherein

some of the plurality of plug holding parts hold first optical connector plugs, and the remaining of the plurality of plug holding parts hold second optical connector plugs, and

the plug holding parts holding the second optical connecting plugs protrude on the adapter side beyond the plug holding parts holding the first optical connector plugs.

7. The optical connector according to claim 6 , wherein

the second optical connector plugs are individually disposed on both end sides in the intersecting direction, and

the first optical connector plugs are disposed between a plurality of the second optical connector plugs.

8. The optical connector according to claim 6 , wherein

both of the first optical connector plug and the second optical connector plug have an optical fiber and a ferrule configured to hold the optical fiber, and

an end portion of the ferrule of the second optical connector plug is located on the adapter side beyond an end portion of the ferrule of the first optical connector plug.

9. The optical connector according to claim 8 , wherein

the second optical connector plug protrudes on the adapter side beyond the first optical connector plug.

10. The optical connector according to claim 6 , comprising

a grip part configured to grip the holder.

11. The optical connector according to claim 6 , comprising

at least one or more connector plug groups having six optical connector plugs arranged in the intersecting direction.
