Adapter for optical connectors
An optical fiber connector assembly comprises at least one connector having a latching arm for coupling to an adapter, and a remote release tab having a protrusion configured to cooperate with the adapter to depress said latching arm when the remote release tab is pulled relative to the adapter. The optical fiber connector assembly may further be configured to allow reversing its polarity.
1. An adapter for mating with optical fiber connectors, the adapter comprising:
an outer housing having a first end portion and a second end portion spaced apart along a longitudinal axis, the outer housing comprising a first side wall and a second side wall spaced apart along a lateral axis perpendicular to the longitudinal axis, the outer housing having a width extending along the lateral axis from the first side wall to the second side wall, the outer housing comprising a upper wall and a lower wall spaced apart along a transverse axis oriented perpendicular to the lateral axis and perpendicular to the longitudinal axis, each of the upper wall and the lower wall having an inner surface, the outer housing defining a plurality of channels spaced apart along the width, each of the channels being configured to receive an optical fiber connector, the plurality of channels including first and second channels; and
a first longitudinal rib formed on the inner surface of the upper wall at a location spaced apart along the width of the outer housing between the first side wall and the second side wall and a second rib formed on the inner surface of the lower wall at a location spaced apart along the width of the outer housing between the first side wall and the second side wall, the first and second ribs being aligned along the width of the outer housing, the first rib being spaced apart from the second rib along the transverse axis by a transverse gap,
wherein the first longitudinal rib and the second longitudinal rib are located between the first and second channels.
2. The adapter as set forth in claim 1 , wherein the upper wall comprises a first latch opening aligned with the first channel and a second latch opening aligned with the second channel, the first rib being spaced apart between the first latch opening and the second latch opening along the width.
3. The adapter as set forth in claim 2 , wherein the adapter is configured to receive a first one of the optical fiber connectors in the first channel and a second one of the optical fiber connectors in the second channel such that:
a flexible latch arm of the first optical fiber connector is latched with the first latch opening and a front section of a remote release of the first optical fiber connector is received in the first channel at a location spaced apart from the first latch opening along the longitudinal axis toward the second end portion of the outer housing; and
a flexible latch arm of the second optical fiber connector is latched with the second latch opening and a front section of a remote release of the second optical fiber connector is received in the first channel at a location spaced apart from the second latch opening along the longitudinal axis toward the second end portion of the outer housing.
4. The adapter as set forth claim 3 , wherein the first channel is configured to allow the front section of the remote release of the first optical fiber connector to slide along the flexible latch arm of the first optical fiber connector within the first channel toward the first end portion of the outer housing to depress the flexible latch arm of the first optical fiber connector and wherein the second channel is configured to allow the front section of the remote release of the second optical fiber connector to slide along the flexible latch arm of the second optical fiber connector within the second channel toward the first end portion of the outer housing to depress the flexible latch arm of the second optical fiber connector.
5. The adapter as set forth in claim 4 , wherein the upper wall is configured to unlatch from the flexible latch arm of the first optical fiber connector when the flexible latch arm of the first optical fiber connector is depressed and the upper wall is configured to unlatch from the flexible latch arm of the second optical fiber connector when the flexible latch arm of the second optical fiber connector is depressed.
6. The adapter as set forth in claim 2 , wherein the lower wall is free of latch openings.
7. The adapter as set forth in claim 2 , wherein the lower wall is configured to slidably engage each of the first and second optical fiber connectors without latching.
8. The adapter as set forth in claim 1 , wherein the first longitudinal rib has a first height along the transverse axis and the second longitudinal rib has a second height along the transverse axis, the first height being greater than the second height.
9. The adapter as set forth in claim 1 , wherein each of the first and second channels opens through the first end portion of the outer housing.
10. The adapter as set forth in claim 9 , further comprising a transverse wall extending between the upper wall and the lower wall at a location longitudinally spaced apart from the first end portion of the outer housing.
11. The adapter as set forth in claim 10 , wherein the transverse wall includes a socket in each of the first and second channels configured to receive a ferrule of one of the optical fiber connectors.
12. The adapter as set forth in claim 11 , wherein the socket in each of the first and second channels comprises a pair of cylindrical sockets in each of the first and second channels, each pair of sockets configured to receive a pair of cylindrical ferrules of one of the optical fiber connectors.
13. The adapter as set forth in claim 1 , wherein each of the optical fiber connectors is a multi-fiber connector comprising a multi-fiber ferrule.
