Abstract: An optical connector holding two or more LC-type optical ferrules is provided. The optical connector includes an outer body, an inner front body accommodating the two or more LC-type optical ferrules, ferrule springs for urging the optical ferrules towards a mating receptacle, and a back body for supporting the ferrule springs. The outer body and the inner front body are configured such that four LC-type optical ferrules are accommodated in a small form-factor pluggable (SFP) transceiver footprint or eight LC-type optical ferrules are accommodated in a quad small form-factor pluggable (QSFP) transceiver footprint. A connector is released by pulling distally on boot assembly until receptacle hook is displaced from receptacle hook recess at a proximal end of connector.

Abstract: Connector assemblies having an adjustable polarity are described. For example, at least two ferrules may be arranged in a housing of the connector assembly within independent frame plugs in a certain polarity. A top portion of the housing may be removed to allow access to the frame plugs. Accordingly, an installer may open the housing, switch the polarity of the ferrules, and then re-couple the top portion to the housing. In another example, the connector assembly may include a latch that may rotate about the connector assembly from a first polarity position to a second polarity position. The connector assembly may include a compression element that may facilitate the rotation of the latch when the compression element is compressed. In this manner, the latch may be rotated to a different polarity position to allow the connector assembly to be connected to an adapter using a different polarity.

Abstract: Multi-fiber ferrules may be produced with tapered bodies and guide pin holes that have fluted internal surfaces with projections for engaging the guide pins, and channels for capturing any foreign material that may accumulate on or around the guide pins, thereby providing improved consistency in fiber connections during mating of the ferrules.

Abstract: A very small form factor multifiber fiber optic connection system includes an adapter and mating connectors with complementary prealignment features for prealigning multifiber ferrules in the adapter to prevent guide pin stubbing. The adapter has a prealignment feature formed on at least one interior side of each individual connector port and the connectors have a complementary prealignment formation along a side wall of the connector housing assembly. Each prealignment feature slidably engages the prealignment formation of a fiber optic connector as the fiber optic connector is inserted into the individual connector port to prealign a multifiber ferrule of the fiber optic connector in the adapter.

Abstract: A new fiber optic connector provides a very small form factor with reduced size. The fiber optic connector may comprise a single-body housing having a front end and rear end in a longitudinal direction, two ferrules accommodated in the housing and protruding from the front end of the housing, a back housing positioned adjacent to the rear end of the housing, two springs positioned between the two ferrules and the back housing to urge the two ferrules to move forward, and a boot assembly connected to the rear end of the housing. The housing comprises a latch arm extending obliquely upwards, and the latch arm is in a depressed state when the fiber optic connector is mating with an adapter.

Abstract: The fiber optic adapter may include a main body having a first end portion and a second end portion spaced apart along a length direction, the first end portion having at least a first port configured for receiving at least one ferrule, the second end portion having at least a second port configured for receiving a fiber optic connector; and a sleeve holder provided within the main body and between the first end portion and second end portion such that the first port is in communication with the second port to establish an optical connection. The first port has holding elements to define a receiving space to receive the ferrule, and the receiving space is configured to be expanded when inserting the at least one ferrule into the first port. The fiber optic adapter may receive a ferrule without the need of an outer housing or a spring.
