Disclosed are structures and methods for active optic cable (AOC) assembly having improved thermal characteristics. In one embodiment, an AOC assembly includes a fiber optic cable having a first end attached to a connector with a thermal insert attached to the housing for dissipating heat from the connector. The AOC assembly can dissipate a suitable heat transfer rate from the active components of the connector such as dissipating a heat transfer rate of 0.75 Watts or greater from the connector. In one embodiment, the thermal insert is at least partially disposed under the boot of the connector. In another embodiment, at least one component of the connector has a plurality of fins. Other AOC assemblies may include a connector having a pull tab for dissipating heat from the assembly.

The invention relates to a transparent auxiliary ring for the adjustment, for the long-term stable operation and for protection of fiber-coupled laser arrangements.

An optical transceiver includes a housing, a rib structure mounted on an inner surface of the housing, an optical communication module accommodated in the housing, and a heat conductive module. A gas flow passage is formed between each pair of adjacent ribs of the rib structure. The optical communication module includes a substrate and an optical communication component, and the optical communication component is in thermal contact with the housing. The heat conductive module is in thermal contact with the rib structure and the optical communication component.

A ferrule includes a ferrule matrix, an optical fiber, and a dielectric reflective film. The optical fiber is disposed in an accommodating through hole of the ferrule matrix, and the dielectric reflective film covers an optical transmission surface of the optical fiber and a surface that is of the ferrule matrix and that faces a matching ferrule. The dielectric reflective film has a through hole, such that the dielectric reflective film does not shield a main optical path area of the optical transmission surface of the optical fiber. A reflective band of the dielectric reflective film includes at least a part of a communication band of the optical fiber. In this way, when light from the matching ferrule is transmitted to the ferrule matrix and the optical fiber, the dielectric reflective film reflects the light.

A fiber optic connector including a connector body and a cable, the cable including optical fibers and a non-circular jacket. The fiber optic connector additionally including a resilient jacket, the resilient jacket is rotatable relative to the non-circular jacket. The resilient jacket is enabled to rotate by an insert which includes an outer profile which engages with an inner profile of the resilient jacket. The insert includes an inner profile which prevents relative rotation between the insert and the non-circular jacket.

An optical fiber heat exchanger includes an outer body and an inner body inserted into the outer body. The inner body includes a plurality of guide walls to guide a cooling liquid through the optical fiber heat exchanger to exchange heat from an optical fiber inserted in the optical fiber heat exchanger, a first set of parallel straight channels, extending along an inlet portion of the inner body, formed by a first subset of the plurality of guide walls, a set of U-shaped channels, extending through a transition section of the inner body, formed by a second subset of the plurality of guide walls, and a second set of parallel straight channels, extending along an outlet portion of the inner body, formed by a third subset of the plurality of guide walls.
