A preconnectorized outdoor cable streamlines the deployment of optical waveguides into the last mile of an optical network. The preconnectorized outdoor cable includes a cable and at least one plug connector. The plug connector is attached to a first end of the cable, thereby connectorizing at least one optical waveguide. The cable has at least one optical waveguide, at least one tensile element, and a cable jacket. Various cable designs such as figure-eight or flat cables may be used with the plug connector. In preferred embodiments, the plug connector includes a crimp assembly having a crimp housing and a crimp band. The crimp housing has two half-shells being held together by the crimp band for securing the at least one tensile element. When fully assembled, the crimp housing fits into a shroud of the preconnectorized cable. The shroud aides in mating the preconnectorized cable with a complimentary receptacle.

An optical sense signal generator for medical device's having a photonic catheter containing optical conductors conducting light energy in two directions between electronics at a catheter proximal end and electrical stimulation and sensing components at a catheter distal end. An optical unit receives light delivered from the catheter proximal end and transmits a first portion of the light while diverting a second portion of the light. The transmitted light is fed to an opto-electrical converter for conversion into electrical stimulation signals. The diverted light is directed to one or more optical modulators that modulate the diverted light output under an applied electrical signal. An electrical circuit generates electrical sense signals corresponding to one or more sensed physiological conditions and provides the signals to the optical modulator(s). This results in modulation of the diverted light output into optical sense signals that are transmitted to the catheter proximal end.

An optical connector 20 in which an urging means 26 which urges a ferrule 24, in which an optical fiber 22 is installed and fixed and which has a polished front end face 23, toward the tip face 23 is positioned behind a connecting mechanism 25 which connects the optical fiber 22 on the ferrule 24 side with a separately inserted optical fiber 22a on the rear end side of the ferrule 24 on the opposite side to the tip face 23. Since the mechanism 25 is constituted by utilizing a mechanical splice and opened/closed by means of an opening member inserted into a port 39 opened in the transversal direction to the aligning axial direction, the operating/closing operation does not interfere with the urging means 26 and the workability is improved. A housing 21 for optical connector for housing the ferrule 24 of the optical connector 20. When this housing 21 is used, the workability of the assembling work of the connector 20 can be improved, because the connector 20 can be assembled easily by only inserting the ferrule 24, connecting mechanism 25 which connects the optical fibers to each other on the rear end side of the ferrule 24, and a stop ring 27 housing the mechanism 25.
