Narrow width adapters and connectors with pull tab release
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.
1. A connection system comprising:
a fiber optic receptacle of one of an adapter or an SFP defining a connector port, the fiber optic receptacle having a top wall and a bottom wall above and below the connector port, respectively, the fiber optic receptacle having a single bendable latch element in the connector port between the top wall and the bottom wall; and
a narrow width fiber optic connector for releasable connection to said one of the adapter or the SFP, the narrow width fiber optic connector comprising:
a plurality of ferrules with at least one optical fiber within each ferrule, the ferrules being arranged in side-by-side relation and defining a ferrule plane;
a housing configured to hold the plurality of ferrules and further comprising a connector recess, the housing being configured to plug into the connector port of the fiber optic receptacle whereby the single bendable latch element engages the connector recess to latch the narrow width fiber optic connector with the fiber optic receptacle;
a cable boot extending rearward from an adjacent portion of the housing along a cable boot length; and
a single pull tab having a distal portion and a ramp area configured to disengage the bendable latch element from said connector recess, the distal portion of the pull tab being located above the ferrule plane and overlying the plural optical fibers, the pull tab being mounted on the housing for movement between a displaced position and an undisplaced position, the pull tab releasing the plurality of ferrules from the fiber optic receptacle;
wherein when the housing is plugged into the connector port, the single bendable latch element is located between the housing and the top wall of the fiber optic receptacle entirely above the ferrule plane and the connection system is free of any component in the connector port between the housing and the bottom wall of the fiber optic receptacle below the ferrule plane.
2. The connection system of claim 1 , further comprising one of a multi-fiber MT ferrule and at least one LC ferrule.
3. The connection system of claim 1 , wherein a pitch between adjacent optical fibers is less than or equal to about 5.25 mm.
4. The connection system of claim 1 , wherein each optical fiber is disposed within an LC ferrule or a multi- fiber MT ferrule.
5. A connection system comprising:
a fiber optic receptacle of one of an adapter or an SFP defining a connector port, the fiber optic receptacle having a top wall and a bottom wall above and below the connector port, respectively, the fiber optic receptacle having a single bendable latch element in the connector port between the top wall and the bottom wall; and
a narrow pitch fiber optic connector for releasable connection to said one of the adapter or the SFP, the narrow pitch fiber optic connector comprising:
a plurality of LC optical ferrules arranged such that a pitch of said narrow pitch connector is less than about 5.25 mm, the plurality of optical ferrules being arranged side-by-side and defining a ferrule plane;
a housing configured to hold the plurality of LC optical ferrules and further comprising a connector recess, the housing being configured to plug into the connector port of the fiber optic receptacle whereby the single bendable latch element engages the connector recess to latch the narrow width fiber optic connector with the fiber optic receptacle; and
a single pull tab having a distal portion and a ramp area configured to disengage the bendable latch from said connector recess, the distal portion of the pull tab being located above the ferrule plane and overlying the plural optical fibers, wherein the pull tab is mounted on the housing for movement between a displaced position and an undisplaced position;
wherein when the housing is plugged into the connector port, the single bendable latch element is located between the housing and the top wall of the fiber optic receptacle entirely above the ferrule plane and the connection system is free of any component in the connector port between the housing and the bottom wall of the fiber optic receptacle below the ferrule plane.
6. The connection system of claim 5 , wherein the pull tab includes a distal end for remotely unlatching the narrow pitch connector.
7. The connection system of claim 5 , wherein the narrow pitch connector is a duplex connector.
8. The connection system of claim 5 , wherein the housing includes a bottom housing and a top housing coupled to the bottom housing.
9. The connection system of claim 8 , wherein the bottom housing includes a side wall configured to open.
10. The connection system of claim 9 , wherein the side wall includes a raised profile at a rear end thereof.
