normally it is co-axial cable, i think thts how u spell it, u can get it from any aerial or satalite shop, also ask them from some 'F' types normal or snap and seal 'F' types and a couple of barrels (joiners) jus reconnect the cable using those, and u lose about 1 db signal but tht is nothin it wont effect your broadband in anyway, if optic cable i think it uses same princable 'F' types but not 100% sure, if cable has a metal round small core and and u can see white around it but a bit thicker then its co-axial

maybe tht will help
