Abstract
Narrow width fiber optic connectors having spring loaded remote release mechanisms to facilitate access and usage of the connectors in high density arrays. A narrow width fiber optic connector comprises a multi-fiber connector, wherein a width of said narrow width fiber optic connector is less than about 5.25 mm, a housing configured to hold the multi-fiber connector and further comprising a connector recess, and a pull tab having a ramp area configured to disengage a latch of one of an adapter and an SFP from said connector recess. The pull tab may include a spring configured to allow the latch of one of the adapter and the SFP to engage with the connector recess.
Claims (18)
1. An optical fiber connector configured for mating with a receptacle, the optical fiber connector comprising:
first and second LC ferrules configured to hold first and second optical fibers;
a connector housing assembly having a front end portion and a rear end portion spaced apart along a longitudinal axis, the connector housing assembly configured to hold the first and second LC ferrules such that the first and second LC ferrules are exposed through the front end portion for making an optical connection;
a depressible latching arm connected to the connector housing assembly for latching with the receptacle when the optical fiber connector is mated with the receptacle to releasably retain the optical fiber connector in the receptacle; and
a remote release connected to the connector housing assembly for movement relative to the connector housing assembly along the longitudinal axis, the remote release being configured to be pulled rearward along the longitudinal axis to depress the depressible latching arm for releasing the optical fiber connector from the receptacle;
wherein the connector housing assembly is configured to hold the first and second LC ferrules at a pitch of 4.8 mm or less, and
wherein the remote release is configured to be directly coupled to the connector housing assembly, and the remote release contacts and depresses the depressible latching arm when pulling rearward along the longitudinal axis.
2. The optical fiber connector as set forth in claim 1 , wherein:
the connector housing assembly defines a groove, the remote release being slidably received in the groove;
the remote release comprises a lower portion and an upper portion, the lower portion being wider than the upper portion; and
the groove includes an inner portion and an outer portion, the inner portion being wider than the outer portion, the inner portion of the groove being configured to slidably receive the lower portion of the latch release and the outer portion of the groove being configured to slidably receive the upper portion of the latch release such that the connector housing assembly retains the latch release in the groove.
3. The optical fiber connector as set forth in claim 1 , wherein the remote release comprises a front section and wherein the optical fiber connector is configured such that the front section is yieldably biased forward along the longitudinal axis.
4. The optical fiber connector as set forth in claim 3 , further comprising a resilient biasing member engaging the front section of the remote release to yieldably bias the remote release forward.
5. The optical fiber connector as set forth in claim 4 , wherein the depressible latching arm is configured to engage the front section of the remote release at a first point of contact and the resilient biasing member is configured to engage the front section of the remote release at a second point of contact, the second point of contact being rearwardly spaced apart from the first point of contact along the longitudinal axis.
6. The optical fiber connector as set forth in claim 1 , further comprising a single strain relief boot, the first and second optical fibers extending though the single strain relief boot.
7. The optical fiber connector as set forth in claim 6 ,
wherein the first and second ferrules are spaced apart along a transverse axis perpendicular to the longitudinal axis, wherein the connector housing comprises a single housing piece having first and second walls spaced apart along the transverse axis outboard of the first and second ferrules such that the first and second ferrules are located in a region between the first and second walls along the transverse axis.
8. The optical fiber connector as set forth in claim 1 , wherein the connector housing assembly is provided with a groove on a top where the depressible latching arm is located, and the remote release is slidably received in the groove.
