## Abstract

An optical connection system for use with a receptacle and an optical cable assembly includes an adapter and connector. The adapter has an adapter latch element, and the connector has a connector latch element. A delatch actuator with a delatch arm is disposed on the connector housing for movement from a locking position to an unlocking position. One of the adapter latch element and connector latch element is a bendable latch hook and the other is a locking channel. When the connector housing is mated with the adapter, the delatch arm allows the bendable latch hook to latch with the locking channel in the locking position and unlatches the bendable latch hook from the locking channel as it moves to the unlocking position. An actuator lock movably supports a blocking member on the connector for selectively blocking the delatch actuator from moving to the unlocking position.

## Claims

### Claim at position 1

1-26. (canceled)

### Claim 27

An optical connector configured to latch with an adapter, the optical connector comprising:
a connector housing having an adapter interface end portion and a cable end portion and having an interior passage extending from the adapter interface end portion through the cable end portion, the cable end portion being configured to receive an optical cable;
an actuator disposed on the connector housing for movement relative to the connector housing from a first position to a second position whereby the actuator is configured to unlatch the optical connector from the adapter; and
an actuator lock comprising a blocking member supported on the connector housing for movement relative to the connector housing between a blocking position and a release position, wherein in the blocking position, the blocking member is configured to block the actuator from moving from the first position the second position, and in the release position, the blocking member is positioned relative to the actuator such that the actuator can move from the first position to the second position without being blocked by the blocking member.

### Claim 28 (depends on 27)

The optical connector as set forth in claim 27, further comprising a cable boot configured to releasably connect to the cable end portion of the connector housing at a coupled position.

### Claim 29 (depends on 28)

The optical connector as set forth in claim 28, wherein the cable boot in the coupled position is configured to interfere with the blocking member moving from the blocking position to the release position.

### Claim 30 (depends on 29)

The optical connector as set forth in claim 29, wherein the cable boot is movable relative to the connector housing to a displaced position at which the cable boot is positioned so that the blocking member can clear the cable boot to move from the blocking position to the release position.

### Claim 31 (depends on 30)

The optical connector as set forth in claim 30, wherein the cable boot is configured to threadably connect to the cable end portion of the connector housing and threadably adjust from the coupled position to the displaced position.

### Claim 32 (depends on 27)

The optical connector as set forth in claim 27, wherein the actuator lock further comprises a locking plate connecting the blocking member to the connector housing, the locking plate including a guide slot, the blocking member being slidably received in the guide slot for movement between the blocking position and the release position.

### Claim at position 8

33-34. (canceled)
