A receptacle includes a cooling channel that is positioned between a top port and a bottom port. A transfer member is positioned in the cooling channel and is configured to direct heat from an inserted plug module into the cooling channel. Air flowing through the cooling channel acts to remove thermal energy from the receptacle. A connector system may include a plug module that can be inserted into such a receptacle and the plug module can include grooves to help allow for direct cooling of the plug module, even when inserted into the receptacle.

A multicore fiber-to-single core fiber adapting device, also referred a fan-in/fan-out (FIFO) device. More specifically, an optical fiber system comprising a multicore fiber, a tapered glass device that it is configured to connect a multicore fiber to a multiple single core fiber, and/or single mode fibers, advantageously having one or more protective layers to protect the tapered device. Associated methods of manufacture.

An optical-fiber holding component disposed in a ferrule holding a plurality of optical fibers, which respectively have at least one core in a region shifted from a region on a center axis and are arranged in a first direction intersecting with the center axis line, is disclosed.

The optical-fiber holding component comprises a holding part defining a position of each of coating removed portions in a plane perpendicular to the center axis and holding the coating removed portions, each of the coating removed portions being obtained by removing a resin coating by a predetermined length from a tip end of each of the optical fibers; and a fixing part arranged side by side with the holding part in a second direction along the center axis, resin coated portions of the optical fibers being fixed to the fixing part.

In one embodiment, a pluggable module has fins along a length of its shell, and a planar gap on its shell in front of the fins. The fins may rise higher than an industry-standard pluggable module. The planar gap provides for a pressure drop as air reaches the fins, and thereby improves air flow. The pluggable module plugs into a port of a cage. A key pattern or rotating door on the port is configured to allow the pluggable module's fins to pass through, while also placing a height limit on non-fin regions of the shell.

A self-cleaning optical fiber connector system for ensuring dust or contaminants are cleared from an optical connection interface is disclosed. In one aspect, the optical fiber connector system includes a connector joining first and second connectors. The adapter has a main body defining a central opening within which the connectors are received. The connectors each include a fiber optic cable secured by a ferrule. In one aspect, the ferrule defines an airflow passageway that narrows between a second opening and a first opening proximate an end face of the cable optical core and cladding. The connectors are constructed such that, as each connector is being inserted into the connector, an air flow is generated through the ferrule airflow passageway, and optionally through an exhaust airflow passageway in the connector. The generated airflow clears debris from the exposed end faces. Electrostatic precipitation may also be used to aid in clearing dust and debris, alone or in combination with air flow effects.
