An optical fiber connector includes an outer housing, a rear member sleeved on a rear end of the outer housing, a polarity key, and a release pull lever. The polarity key includes a body part extending from the rear member and located on one side of the outer housing, a latching part formed with a cutout and having a first sloping surface, and a locking protrusion extending from the latching part. The release pull lever is disposed on the outer housing and has a driving portion protruding into the cutout and being in sliding contact with the first sloping surface, such that rearward movement of the release pull lever drives the locking protrusion to move close to the outer housing.

A new boot for a fiber optic connector has a ribbed back portion, a center portion, and a forward extending portion that can be used to insert and remove the fiber optic connector to receptacle. The ribbed back portion has grasping elements and is connected to the center portion. The center portion is removably connected to a crimp body that is in turn connected to the connector housing. The front extension is connected to the fiber optic connector and also provides a keying feature depending on the side of the fiber optic connector on which it is installed.

An outdoor rated ingress protected one-piece adapter with a first and second end. First end accepts a fiber optic adapter configured to accept a LC, SN, CS, SC or MPO fiber ferrule assembly. A second end accepts a cable gland assembly that secures a cable therein. The first end is configured to accept an outdoor rated connector having a fiber connector therein. The connector/adapter assembly is rated for outdoor use.

Systems and methods of using a multiport assembly and associated components are disclosed. The multiport assembly can include a multiport device that communicatively couples multiple sets or pairs of connectors, such as optical connectors or electrical connectors, together. The multiport assembly can also include an auxiliary port device that couples to the multiport device to expand the capacity of the multiport assembly. Both the multiport and auxiliary port devices can be selectively configured to receive specific types of connectors by selectively coupling to different types of adapters, where the types of adapters correspond to the types of connectors. When coupled to the multiport or auxiliary port devices, the adapters facilitate the formation of the communication between its corresponding set of connectors.

A ferrule holder assembly can support groupings of a transceiver ferrules in an optical connector interface of an optical transceiver. A first holder body holds a first grouping of transceiver ferrules and has a holder-to-holder interface. A second, typically identical, holder body holds a second grouping of transceiver ferrules. The holder-to-holder interface of the first holder body engages the holder-to-holder interface of the second holder body to operatively align the first holder body with the second holder body to position the first grouping of transceiver ferrules and the second grouping of transceiver ferrules in the optical connector interface for making optical connections to one or more optical connectors plugged into the optical connector interface. The ferrule holder assembly can be used in combination with pre-terminated fiber arrays to couple an optical interface to a circuit board in a transceiver.

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.

A fiber optic cable assembly includes a fiber optic cable and a fiber optic connector. The cable includes a jacket having an elongated transverse cross-sectional profile that defines a major axis and a minor axis. Strength components of the cable are anchored to the connector. The fiber optic connector includes a multi-fiber ferrule defining a major axis that is generally perpendicular to the major axis of the jacket and a minor axis that is generally perpendicular to the minor axis of the jacket. Certain types of connectors include a connector body defining a side opening that extends along a length of the connector body; a multi-fiber ferrule configured for lateral insertion into the connector body through the side opening; and a cover that mounts over the side opening after the multi-fiber ferrule has been inserted into the connector body through the side opening.

Waveguide substrates, waveguide substrate assemblies, and methods for fabricating waveguide substrates are disclosed. In one embodiment, a waveguide substrate includes an input edge, an output edge, and at least one waveguide within the waveguide substrate. The waveguide substrate further includes at least one input alignment feature within the input edge adjacent to the input end of the at least one waveguide, wherein the at least one input alignment feature is fabricated from a material of the waveguide substrate. The waveguide substrate may also include at least one output alignment feature within the input edge adjacent to the output end of the at least one waveguide, wherein the at least one output alignment feature is fabricated from the material of the waveguide substrate.

An optical connector system includes: a first optical connector that includes a first shutter; and a second optical connector to be connected to the first optical connector. The first shutter opens by inclining toward the second optical connector when the first shutter comes into contact with the second optical connector.

An assembly for assembling optical fiber with at least two pairs of MPO contacts. The optical contacts being of the multifiber push-on type. The assembly includes a socket including MPO contacts cooperating with a plug. The plug includes, through axial openings configured to receive the MPO contacts, a first positive-location element positioned in each axial opening of the plug and a second positive-location element positioned on each corresponding MPO contact. A holding element configured to hold the MPO contacts in the plug. The plug shape cooperates with the shape of the socket to ensure coupling thereof. The socket includes locking elements to lock the MPO contacts. Each MPO contact of the plug is locked with the corresponding MPO contact in the socket.
