 an electrical wire emplaced within the rod, providing an electrical path, and 
 an optical fiber emplaced within the rod; 
   wherein the electrical wire extends continuously out of the end of the rod into the tool; and   wherein the electrical path extends to an electrical connector at the end of the tool, providing access to the electrical path on the exterior side proximate to the end of the tool.   
     
     
         2 . The system of  claim 1  wherein the optical fiber extends into the tool. 
     
     
         3 . The system of  claim 2  wherein the tool further comprises a first chamber and a ported chamber, and wherein the electrical wire extends into the first chamber of the tool. 
     
     
         4 . The system of  claim 3  wherein the electrical path extends through the ported chamber to the electrical connector at the end of the tool. 
     
     
         5 . The system of  claim 3  wherein the ported chamber is isolated from the first chamber. 
     
     
         6 . The system of  claim 3  wherein the pressure in the ported chamber is isolated from the first chamber. 
     
     
         7 . The system of  claim 3  wherein the optical fiber is optically connected to a sensor in communication with the ported chamber. 
     
     
         8 . A system for providing an electrical path from an intervention rod to the end of a tool, the system comprising:
 a semi stiff wellbore intervention rod;   a tool mechanically attached to an end of the intervention rod;   wherein the intervention rod further comprises
 an electrical wire emplaced within the rod, providing an electrical path, and 
 an optical fiber emplaced within the rod; 
   wherein the tool further comprises a first chamber and a ported chamber;   wherein the electrical wire extends continuously out of the end of the rod into the first chamber of the tool;   wherein the optical fiber extends to a sensor in communication with the ported chamber;   wherein the pressure in the ported chamber is isolated from the first chamber; and   wherein the electrical path extends through the ported chamber to an electrical connector at the end of the tool, providing access to the electrical path on the exterior side proximate to the end of the tool.   
     
     
         9 . An electrically-enabled semi-stiff wellbore rod and guide nose system, the system comprising:
 at least one electrical cable disposed in a semi stiff wellbore intervention rod;   a termination housing having one end connected to the end of the rod, the termination housing containing fiber optic sensors and the at least one electrical cable;   a crossover connected to the other end of the termination housing;   a ported coupling comprising:
 a first end connected to the end of the crossover, and 
 a lower termination disposed on a second end of the ported coupling for connection to devices; 
   wherein
 the at least one electrical cable extends through the interior of the crossover from the termination housing and to the ported coupling, and 
 one or more pressure-tight tubes surround the at least one electrical cable in the interior of the crossover; and 
   wherein
 the at least one electrical cable is not in pressure communication with the interior of the crossover, and 
 the at least one electrical cable terminates for electrically connectable reception by devices at the lower termination.
