    Abstract: An optical fiber connection system (600) configured to interconnect a plurality of first and second optical fibers (54, 54′) is described. The connection system comprises a first bare fiber holder (620) that includes a clamping plate (540) having an interconnection portion (544) with a generally planar surface, wherein bare ends of the plurality of first optical fibers (54) are disposed adjacent to interconnection portion (544) and wherein the plurality of first optical fibers (54) are secured in the first bare fiber holder (620) at a first distance from the bare ends of the plurality of first optical fibers (54) and a second bare fiber holder (620′) that includes a splicing plate (580) having a plurality of alignment channels (585), wherein a bare end of each of the second optical fibers (54′) extend at least partially into one of the plurality of alignment channels (585) and wherein the plurality of second optical fibers (54′) are held at a second distance from the bare ends of the plurality of second optical fibers (54′).

    Abstract: An optical connector having at least one removable integrated assembly tool for terminating an optical fiber cable is described. The connector comprises a housing configured to mate with a receptacle, a collar body disposed in the housing, a backbone that retains the collar body in the housing, a removable funnel-shaped and a fiber boot. The collar body secures a ferrule secured at a first end thereof, and includes mechanical element disposed in an intermediate portion and a buffer clamping portion near a second end of the collar body. The backbone has a mounting structure surrounding a central bore at one end. The funnel-shaped fiber guide attaches to the mounting structure to facilitate insertion of an optical fiber into the connector, and wherein the fiber boot is attachable to the mounting structure after the fiber guide has been removed.

    Abstract: A ruggedized cable connection structure configured to direct mate first and second ruggedized optical fiber connectors is disclosed. The connection assembly has a housing having a channel extending from a first end of the housing through to the second end of the housing, an adapter secured within the channel near a midpoint of the housing to enable direct mating of the first and second ruggedized optical fiber connectors, and an integral mounting flange extending from the housing to allow connection to a mounting surface.

    Abstract: An optical fiber connector includes a housing configured to mate with a receptacle, a collar body that includes a fiber stub and a mechanical splice device, a backbone to retain the collar body within the housing, and a boot. The backbone includes a fiber jacket clamping portion to clamp a jacket portion that surrounds a portion of the terminated optical fiber upon actuation. The boot actuates the fiber jacket clamping portion of the backbone upon attachment to the backbone. The optical fiber connector can be terminated in the field without the need to use a separate termination platform or tool.

    Abstract: An optical system including first and second optical elements for guiding light therein. For each optical element, the propagating light enters or exits the optical element through a coupling surface of the optical element. The coupling surfaces of the optical elements face, and align with, each other so that light propagating in one of the optical elements exits the optical element through the coupling surface of the optical element and enters the other optical element through the coupling surface of the other optical element. The coupling surfaces are separated from each other and define a region therebetween. The region is filled with a coolant, the coolant substantially surrounding at least one of the first and second optical elements.
