Abstract: An optical connector assembly having an adapter with a first and second end. Either end can accept a connector with a removable, detachable and replaceable coupling nut that when removed, connector outer diameter is substantially reduced, thereby allowing said connector to be inserted through a conduit having an inner diameter substantially less than outer diameter of separable coupling nut.

Abstract: Fiber optic connection assemblies that may include hybrid adapters and connector assemblies are generally described. The hybrid adapter may be configured to connect a first connector type and a second connector type, the first connector type being different from the second connector type. For example, the first connector type may be a micro connector and the second connector type may be an LC connector. A connector assembly may be configured as a micro connector having a tension element configured to facilitate optimized optical performance by spring loading the ferrules while maintaining a small form factor.

Abstract: An in-line dust shutter formed as part an adapter. A hinged dust shutter assembly is secured to an adapter wall. A shutter plate covers an opening formed at either end of the adapter to prevent debris from entering the adapter and distorting the light signal between opposing fiber optic connectors. The shutter plate extends at angle alpha from a rotational axis. The shutter plate is biased closed by a bias spring place about a pin of the rotational axis.

Abstract: Various embodiments disclosed herein are directed to a Network system including: a connector comprising a housing comprising a groove running widthwise on a surface of the housing; and a push-pull tab comprising a complementary groove, wherein the push-pull tab is detachably connected to the housing; and a receiver device comprising one or more ports for receiving the connector, the one or more ports having an interchangeable anchor device including a first portion and a second portion; wherein the groove is configured to receive the first portion of the interchangeable anchor device when the connector is inserted into the receiving element, and wherein the complimentary groove is configured to receive the second portion of the interchangeable anchor device when the connector is inserted into the receiving element, the push-pull tab being configured to disengage the second portion of the interchangeable anchor device from the complementary groove when the push-pull tab is moved in a direction away from the connector, thereby disengaging the first portion of the interchangeable anchor device from the grove of the connector. Other aspects are described and claimed.

Abstract: Optical fiber connectors and adapters are disclosed. A connector assembly includes a sleeve seal positioned near a proximal end of the connector, the seal fits over an alignment sleeve contained within an adapter. The connector may include a heat shrinkable tubing covering a distal end of the connector to prevent ingress of moisture and debris. The sleeve seal is compressed by a proximal face of a connector plug frame. The sleeve seal contains a plural of sealing or mating surfaces to prevent the ingress of moisture through the adapter opening into the plug frame housing a ferrule. The adapter further comprises a washer-seal that is placed between an adapter flange face and a module face plate that secures the adapter with connectors therein to a rack of adapters.

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 connection, and a back body for supporting the ferrule springs. A removable inner front body for polarity change is disclosed. A multi-purpose rotatable boot assembly for polarity change is disclosed. The multi-purpose boot assembly can be pushed and pulled to insert and remove the micro connector from an adapter receptacle.

Abstract: A boot assembly having a boot body with a passageway molded from a proximal to distal end of the body. The passageway accepts a repositioning device made of a malleable material such as metal that retains its shape under internal forces of the boot assembly. The boot assembly further comprises one or more cables for fiber optics or power. Bending the flexible boot assembly from a first position to a second position, the flexible boot assembly retains the second position without returning to the first position under the resilient material of the boot
