A cable-jetting installation sleeve can be used to advance a fiber-optic cable through a conduit. The cable-jetting installation sleeve can include a housing and an expandable section. The expandable section can include an opening which can be expanded to receive or remove an end of the cable and contracted to engage the cable with the expandable section. A parachute can be positioned on one end of the cable-jetting installation sleeve. The parachute can be pushed by compressed air in the conduit to advance the cable-jetting installation sleeve through the conduit.
