A factory processed and assembled optical fiber arrangement is configured to pass through tight, tortuous spaces when routed to a demarcation point. A connector housing attaches to the optical fiber arrangement at the demarcation point (or after leaving the tight, tortuous spaces) to form a connectorized end of the optical fiber. A fiber tip is protected before leaving the factory until connection is desired.

An optical connector includes: an optical fiber; a ferrule with an insertion hole that accommodates the optical fiber; a housing that accommodates the ferrule and that includes two lock holes formed therein; two springs that sandwich the optical fiber therebetween, and that bias the ferrule in a forward direction of the optical connector; and a support portion that supports the two springs from a rear direction of the optical connector. The support portion includes a first divided member that is combined with a second divided member and two latch portions locked in the two lock holes. When the insertion hole extends is the front and the rear directions, the two springs are disposed along left and right directions of the optical connector, and a vertical direction is orthogonal to the front, rear, right, and left directions, the two latch portions are disposed side by side in the vertical direction.

A connection structure of the adapter and the connector includes an adapter and a connector engaging with the adapter in a snap-fit manner. The adapter is provided with a mounting hole. A first positioning boss is disposed on the inner wall of the mounting hole. The connector includes a connector housing and a ferrule flange. The connector housing engages with the adapter in a snap-fit manner. A sliding recess and a first positioning recess that communicate with each other are disposed on the connector housing in the axial direction of the connector housing. The first positioning boss is configured to selectively match the sliding recess or the first positioning recess. A first end of the ferrule flange engages with the outer end face of the connector housing in a snap-fit manner. A second end of the ferrule flange extends into the adapter.

The disclosure provides an optic fiber connector, including a ferrule, a holder, a connector body having a plurality of first locking slots, a spring sleeved onto the holder, and a retainer having a plurality of locking hooks. The ferrule is assembled to the holder. The spring, the holder, and the ferrule are received in a space formed between the retainer and the connector body by locking the locking hooks with the locking slots respectively, wherein the spring is compressed by locking such that the retainer, the holder, the spring, and the connector body are abutted with each other.

The present disclosure relates to a ferrule boot for mounting in a multi-fiber ferrule. The ferrule boot may include a body member that has a distal end and a proximal end. The body member may define a plurality of openings that extend lengthwise therethrough with each opening being configured for receiving a respective one of a plurality of optical fibers.

A fiber optic connector along with a tool allows for the changing of the polarity of the fiber optic connector. Keys may be installed in both the top and the bottom of the fiber optic connector, one in a first position and the other in a second position. Using the tool in one back-and-forth motion, the polarity of the fiber optic connector can be changed. The keys have a configuration that resist an incorrect insertion and provide better retention of the keys in the correct configuration due to a better retention force.

A housing for a fiber optic connector includes an opening extending between a front end and a rear end, and having an integral spring stop surface between the front end and the rear end. A front section receives an elastic member into the opening from the front end and the elastic member is engageable with the integral spring stop of the housing. There is a middle section of the main body to transition optical fibers between a fiber optic ferrule and a fiber optic cable. A rear section of the main body has an outer surface to engage a crimp ring.

Devices and methods for connecting optical fibers are provided. In some embodiments, connectors and adaptors for two-fiber mechanical transfer type ferrules are disclosed. In some embodiments, MT connectors, such as simplex, duplex, and quad micro-MT adaptors are disclosed. In some embodiments, MT adaptors, such as simplex, duplex, and quad adaptors are disclosed. In some embodiments, optical fiber cables that modularly coupled with at least one optical fiber connector, adaptor, and other optical fiber cable the cable is configured to provide a remote release from an adaptor receptacle.

A receptacle for receiving and securing one or more fiber optical connectors and ferrule assembly opposing each other in a secured position deploying an interconnect assembly. A first side of the interconnect assembly has one or more sets of opposing hooks at a first end to accept and secure a connector or ferrule assembly. A second end of the interconnect assembly receives a ferrule assembly secured with a stopper.

Fiber optic connectors, cable assemblies and methods for making the same are disclosed. In one embodiment, the optical connector comprises a housing and a ferrule. The housing comprises a longitudinal passageway between a rear end and a front end, and, a part of the rear portion of the housing comprises a round cross-section and a part of the front portion of the housing comprises a non-round cross-section with a transition region disposed between the rear portion and the front portion.
