A fiber optic connector includes: a housing and an integrated ferrule assembly. N positioning keys are formed on an outer periphery of a ferrule tail seat of the ferrule, wherein N is an integer equal to or greater than two, the N positioning keys are spaced at an equal angle around the outer periphery of the ferrule tail seat, and one of the N positioning keys corresponding to an eccentric orientation of an optical fiber secured in the ferrule is cut out to form a cutting portion; (N-1) positioning slots, which correspond to (N-1) positioning keys on the ferrule tail seat, respectively, are formed in the housing, and there is no positioning slot formed in a part of the housing corresponding to the cutting portion, such that the integrated ferrule assembly may be inserted into the housing only when the N-1 positioning keys are aligned with the (N-1) positioning slots respectively. Thus, the fiber optic connector is adapted to be assembled and detached in the field, preventing effectively the ferrule assembly of the fiber optic connector from being inserting into the housing thereof in an incorrect orientation angle.

The present invention relates to an apparatus for damping and monitoring emissions from a light emitting device, particularly a vertical cavity surface emitting laser (VCSEL), comprising: a semi transparent substrate (116), preferably glass; a light emitting device (114) for generating light emission; a damping layer (112) deposited on a surface of the substrate (116); and a pair of electrodes (110,111), each of which being in direct contact with the damping layer (112). The damping layer is adapted to decrease the power level of the light emission of the light emitting device by absorption, to a desired level, for instance, to a level that meets eye safety limits. In addition, the damping layer is photosensitive to the light emission of the light emitting device, thereby allowing the pair of electrodes to output an electric signal corresponding to the power level of the light emission of the light emitting device. In an array arrangement, the damping regions (112) are isolated from each other by a polymer layer (118).

Disclosed is a fiber cable terminal which comprises a cable assembly, a cable fixing portion and a thermal shrinkable tube. The cable assembly includes: an inner sheath through 5 which the fiber can pass; and a protection layer provided outside of the inner sheath. The cable fixing portion includes: an insertion portion to be inserted between the protection layer and the inner sheath; and a fixing portion connected with the insertion portion and positioned outside of the protection layer. The thermal shrinkable tube wraps a part of the fixing portion and a part of the protection layer and fixes the cable fixing portion and the 10 cable assembly together. All the members of the fiber cable terminal are pre-assembled into a sealed one-piece, the sealing performance between the cable fixing portion and the protecting layer is thus improved. The fiber cable terminal is mated with the through hole of the supporting body to improve the sealing performance between the fiber cable terminal and the supporting body.

A plug and receptacle assembly (100) comprises a plug assembly (102) having a pluggable connector (108) and a receptacle assembly (104) having an assembly housing (116) that includes a communication port (105) for receiving the pluggable connector. The plug assembly includes a thermal interface region (120) coupled to the pluggable connector (108). The thermal interface region comprises a series of spaced apart transfer plates that extend parallel to each other. The receptacle assembly includes a heat sink (118) coupled to the assembly housing (116), the heat sink comprising a series of spaced apart transfer plates that define a series of plate-receiving slots of the heat sink. The transfer plates of the thermal interface region are received by the plate-receiving slots of the heat sink such that the transfer plates of the thermal interface region transfer thermal energy generated within the pluggable connector to the transfer plates of the heat sink.
