Abstract: A power plant for a jet-type model airplanes and UAVs includes an electric motor and a cover. The cover receives a portion of the electric motor and a sleeve into which the electric motor is inserted. The sleeve has a plurality of fins to dissipate heat and create openings into the cover. Air from the fan rotor passes through the openings to cool an electronic speed control member and exits a rear opening in the cover. The cover may also have additional openings for air to enter into the cover.

Abstract: A connector is provided for use in fiber to the desk applications. The connector according to the present invention includes a main housing with a passageway therethrough, a ferrule assemble mountable to the main housing, and a splice member. The connector also includes a latch on at least one exterior surface of the main housing to engage a corresponding structure in an adapter sleeve.

Abstract: A multifiber ferrule is provided that includes a ferrule body that defines at least one elongate hole opening through the front face of the ferrule body that, in turn, includes a lead-in portion proximate the front face for guiding the respective alignment member into the elongate hole. The ferrule body at least partially defines one or more elongate holes, such as a guide pin hole or an alignment groove, each having a longitudinal axis extending therethrough. Each elongate hole includes the lead-in portion proximate the front face and an adjacent alignment portion. The lead-in portion expands radially outward from the longitudinal axis in a direction extending from the adjacent alignment portion to the front face of the ferrule body. As such, the opening of the lead-in portion through the front face of the ferrule body is larger in lateral cross-section than the opening of the lead-in portion into the adjacent alignment portion.

Abstract: A jumper management assembly for managing the routing of fiber optic cable jumpers is disclosed. The assembly fits within a conventional equipment rack. The assembly has a panel with two fiber support trays attached on its back side. The assembly also has ports located in the panel near the support trays. An excess length of a fiber optic cable jumper may be routed from the rear of electronics or other components in the equipment rack using the support trays, portals, and panel.

Abstract: A fiber optic cable guide has a curved elongated member that fits between the strain relief boot and optical fiber to allow the fiber optical cable to bend without violating the minimum bend radius of the optical fibers. The fiber optic cable guide also retains at least a portion of the fiber optic cable.

Abstract: The face of a ferrule and ferrule assembly is polished in the present invention so a portion of optical fibers extending therethrough protrude beyond the front face of the ferrules. The ferrules are secured in a polisher and polished with a fibrous material that preferentially etches the ferrule relative to the optical fibers. The front face of the ferrule assembly is polished with a fibrous material having abrasive materials attached thereto, without the need for a slurry.
