Devices, systems, and methods for extending an optical distribution network to an end point in a user's premises over a power line drop cable that supplies metered power to the premises are disclosed. An existing power line drop cable to the premises serves as an intermediate medium to transmit high-bandwidth data from an optical distribution network to a transceiver in a user's premises. Fiber from an optical distribution network connects to an outside-plant optical-to-electronic device comprising at least an optical network unit and a domain master. The device is powered by electricity from the electrical network to which the first power line drop cable is attached. The device can have an electromagnetic-interference filter.

A casing for housing a fiber optic transceiver for use in a fiber optic connector can include a top surface, a bottom surface and one or more lateral surfaces, wherein the top surface and at least one or more lateral surfaces are at least in parts electrically conductive, and wherein the bottom surface of the casing comprises one or more solder pads.

The present invention provides modular trays having cutout features that are configured to engage with a mounting feature of one or more removable rails. The removable rails may be removably secured to a tray body in a plurality of positions to allow a user to install or uninstall rails to support different sized fiber optic modules. For example, a tray may support a twenty-four optical fiber module, two twelve optical fiber modules, or three eight optical fiber modules. Fiber optic enclosures housing the trays can be affixed to the outside of a fiber optic enclosure and allow for easy stacking and unstacking.

An optical receptacle connector includes a receptacle housing defining a contact cavity, an optical cavity, and a card slot at a front of the receptacle housing configured to receive an edge of an optical module circuit board. A contact assembly having receptacle contacts is received in the contact cavity and extend into the card slot to supply power to the pluggable optical generator module to operate a light source. The optical receptacle connector includes a receive optical connector coupled to the receptacle housing having a ferrule holding at least one optical fiber configured to be mated with a supply optical connector of the pluggable optical generator module to receive optical signals from the supply optical connector.

A fiber optic cassette including a body defining a front and an opposite rear and an enclosed interior. A cable entry location is defined in the body for a cable to enter the interior of the cassette. The cable which enters at the cable entry location is attached to the cassette body and the fibers are extended into the cassette body and form terminations at connectors. The connectors are connected to adapters located at the front of the cassette. A front side of the adapters defines termination locations for cables to be connected to the fibers connected at the rear of the adapters. A cable including a jacket, a strength member, and fibers enters the cassette. The strength member is crimped to a crimp tube and is mounted to the cassette body, allowing the fibers to extend past the crimp tube into the interior of the cassette body. A strain relief boot is provided at the cable entry location.

A medical device optical connector lead for coupling with a guidewire including optical fiber is described herein. The connector can include or use a housing defining an aperture, an optical receptacle disposed within the housing, the optical receptacle configured to receive an exposed optical fiber end of the guidewire extending through the aperture, and a chuck configured to clamp around the guidewire. The chuck can be slidable within the housing between a first chuck position wherein the chuck is positioned closer to the optical receptacle than to the aperture and a second chuck position wherein the chuck is positioned closer to the aperture than to the optical receptacle. An actuator can laterally move the chuck between the first position and the second position and concurrently tighten or loosen the chuck.

A network device includes an enclosure, a multi-chip module (MCM), an optical-to-optical connector, and a multi-core fiber (MCF) interconnect. The enclosure has a panel. The MCM is inside the enclosure. The optical-to-optical connector, which is mounted on the panel of the enclosure, is configured to transfer a plurality of optical communication signals. The MCF interconnect has a first end coupled to the MCM and a second end connected to the optical-to-optical connector on the panel, for routing the plurality of optical communication signals between the MCM and the panel.

Fiber optic connectors and connectorized fiber optic cables include connector housings having locking portions defined on the connector housing that allow the connector housing to be selectively coupled to a corresponding push-button securing member of a multiport assembly. Methods for selectively connecting a fiber optic connector to, and disconnecting the fiber optic connector from the multiport assemblies allow for connector housings to be forcibly and nondestructively removed from the multiport assembly.

An optical fiber termination system includes a housing, a cable, and a catch. The housing defines a portion of a passageway and a surface surrounding the passageway. The passageway defines a central axis and the surface defines an interior of the housing. The cable is receivable through the portion of the passageway. The cable includes an optical fiber and defines a longitudinal axis. The catch is receivable in the housing and attachable to and extendable from the cable in a direction transverse to the longitudinal axis such that the catch limits movement of the cable in a direction away from the interior of the housing when the catch is received in the housing and the cable is received through the portion of the first passageway.

The box houses and holds a connection terminal (TC), coupling an end connector (CE) of a drop cable (CD) and an end plug (PE) of an optical cord (CO) of a user and with a base (10) having a front face (10a) including a jaw (20) at a first edge (11) that receives and holds the drop cable (CD), a pair of lateral claws (30) in the middle locking the connection terminal (TC), and a stop (18) at a second edge (12) with a middle window (18a) enabling the optical cord (CO) to pass through. The box also includes a cover (60) with a front wall (61), and end walls (62) with windows (62a) that surround a portion of the jaw (20) and the middle window (18a) of the stop (18), and longitudinal walls (63), that can be locked on the front face (10a) of the base (10).
