In one embodiment, the device comprises a shell, at least one connection port, at least one securing feature passageway, and at least one securing feature. The at least one connection port is disposed on the multiport with the at least one connection port comprising an optical connector opening extending from an outer surface of the multiport to a cavity of the multiport and defining a connection port passageway. The at least one securing feature is associated with the connection port passageway, and the at least one securing feature is disposed within a portion of the at least one securing feature passageway.

Provided is an adapter. The adapter includes a housing and an elastic component. The elastic component is configured to connect the housing with an installation frame. The elastic component includes an installation body, a blocking portion and a clamping elastic piece, the blocking portion and the clamping elastic piece are disposed on the installation body. The installation body is configured to be detachably connected to the housing. A first clamping gap capable of accommodating the installation frame is provided between the blocking portion and the clamping elastic piece.

A light coupling unit includes a first major surface comprising one or more substantially parallel first grooves oriented along a first direction for receiving one or more optical waveguides. A second major surface for slidably contacting a mating light coupling unit comprises an optically transmitting window for propagating an optical signal therethrough, and a region of second grooves and lands configured to capture particulate contaminants in the second grooves.

Disclosed herein are devices and methods for cleaning, verifying cleaning, and coating a ferrule end face in a single housing thereby preventing contamination of the ferrule end face and associated optical fiber end face. Also disclosed herein is a fiber optic assembly including a ferrule; an optical fiber extending through the ferrule to an end face of the ferrule; and a coating on the end face of the ferrule protecting the optical fiber. The coating is prepared by curing a vinyl-terminated polydimethylsiloxane with a crosslinker in the presence of a catalyst.

The present invention provides a dust-proof device for protecting insertion interfaces arranged in the optical receptacle. The dust-proof device comprises a coupling portion and a flexible arm connected to the coupling portion, wherein the flexible arm may swing or scroll at a location where the coupling portion is connected to the flexible arm. Alternatively, in another embodiment, the present invention further provides an optical receptacle having a plurality of coupling structures respectively having a first insertion interface at a first side and a second insertion interface at a second side, each first insertion interface or second insertion interface may couple to the dust-proof device so as to form an optical connector module for preventing the optical receptacle from being contaminated.

The present disclosure relates to systems and method for deploying a fiber optic network. Distribution devices are used to index fibers within the system to ensure that live fibers are provided at output locations throughout the system. In an example, fibers can be indexed in multiple directions within the system. In an example, fibers can be stored and deployed form storage spools.

A factory processed fiber optic ferrule assembly and field installable cable system are configured to pass through tight, microducts when routed to a demarcation point. A connector housing attaches to the fiber optic ferrule assembly at the demarcation point (or after leaving the tight, microducts) to form a connectorized end of the optical fiber. A fiber tip is protected before leaving the factory until connection is desired.

A fiber-optic connector housing (50) and cable (20, 20′) are attached together by an anchor (100, 200). The anchor includes a one-piece main body, a passage (110, 210), and an injection port (130, 230). The passage extends between first (102, 202) and second ends (104, 204) of the anchor. Strength members (40, 40′) of the cable are secured within the passage by a bonding material (90) and are thereby anchored to the connector housing. A proximal end (54) of the connector housing includes first (60) and second housing components (70) which capture the anchor. The passage passes through an optical fiber (30) of the cable. The passage includes first (120, 220), second (170, 270), and third portions (180, 280). The first portion radially positions the optical fiber. The second portion receives the bonding material and the strength members. The third portion receives a jacket (26, 26′) of the fiber optic cable. The injection port delivers the bonding material to the passage. The anchor may further include retention tabs (150) that fit within corresponding receivers (62, 72) within the connector.

Optical filter devices for providing a reflective event in an optical network are disclosed. In one embodiment, the optical filter device comprises an optical filter assembly for reflecting one or more preselected wavelengths and a housing. In one embodiment, the housing comprises a plug end and a receptacle end for optical connection into a link or connection node of an optical network. The housing comprises a passageway between the plug end and the receptacle end, and the plug end comprises a shroud with a single fiber connector footprint. At least a portion of the optical filter assembly is disposed within the passageway of the housing. The optical filter devices disclosed allow the network operator the flexibility to choose where to position a reflective location in the optical network along with the ability to move, add or change the reflective location as desired.
