A multi-fiber, fiber optic connector may include a reversible keying arrangement for determining the orientation for plugging the connector into an adapter to thereby allow for a change in polarity of the connection to be made on site. The connector housing may be configured to engage with a removable key that may be engaged with the housing in at least two different locations to provide the plug-in orientation, or the housing may have slidably displaceable keys movable between multiple positions on the housing.

Fiber optic connectors, cable assemblies and methods for making the same are disclosed. In one embodiment, the optical connector comprises a housing and a multifiber ferrule. The housing comprises a longitudinal passageway between a rear end and a front end, and a rear portion of the housing comprises a keying portion and at least one locking feature integrally formed in the rear portion of the housing.

An example fiber optic connector label is provided that includes a main body section, a first group of fiber designations, and a second group of fiber designations. The main body section includes a top surface and an opposing bottom surface. The main body section includes a lateral axis extending through first and second side edges of the main body section, the lateral axis dividing the main body section into a first side and a second side. The first group of fiber designations is located on the first side of the main body section. The second group of fiber designations is located on the second side of the main body section.

Indicia elements are added to telecommunications components to identify the source of the telecommunications component. Indicia elements can include at least one of a logo, a specific color (e.g. a color different from a non-indicative base color of the telecommunications component), text information, a barcode, a QR code, and a RFID tag. The indicia elements can aid in identifying or tracing network connections, identifying types of connectors and/or cables, labeling the network connections, and identifying a network operator in a multi-network environment.

A fiber optic connector arrangement includes a printed circuit board coupled to a connector housing. The printed circuit board includes a memory storage device that is configured to store physical layer information pertaining to the fiber optic connector arrangement. The printed circuit board also defines contacts that are electrically coupled to the memory storage device to enable the physical layer information to be read from the memory storage device by a media reading interface. A connector assembly includes at least one adapter assembly; a printed circuit board; and a media reading interface. The connector assembly also may include a tactile pressure sensor. The adapter assembly defines at least a first port and a second port that are configured to connect optical fibers of two connector arrangements. One or more connector assemblies can be mounted to a fiber panel system.

An optically traceable patch cord includes a cable extending from a first connector at a first end to a second connector at a second end. A trace assembly in the cable is located between the first end of the cable and the second end of the cable. An optical tracing fiber extends from the trace assembly to one of the first connector and the second connector.

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.

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.

The present disclosure provides embodiments of fiber optic cable connectors, sleeves for fiber optic cable connectors, fiber optic cable adapters and fiber optic connector assemblies that incorporate intelligent systems that can identify presence and exchange information.

Passive optical couplers having passive optical activity indicators and methods of operating the same are disclosed. An example passive optical coupler for passively coupling first and second optical fibers includes a housing including: a first port configured to receive an end of a first optical fiber, and a second port configured to receive an end of a second optical fiber; and a passive optical activity indicator positioned at least partially within the housing, wherein a first portion of the passive optical activity indicator is exposed through the housing, and wherein the passive optical activity indicator is configured to passively illuminate in response to (i) first light propagating in the first optical fiber when the end of the first optical fiber is received in the first port, and (ii) second light propagating in the second optical fiber when the end of the second optical fiber is received in the second port.
