Jokinen was recently placed on waivers by the Hurricanes and cleared. A shootout specialist, the 30-year-old has six goals and 11 points in 33 games this season.
Jokinen had his breakout season in 2009-10, scoring 30 goals and posting 65 points. He finished with 52 and 46 points the past two seasons.
"[He is] a guy I always circle as one of the guys you need to pay attention to on the other team," Penguins coach Dan Bylsma said Wednesday. "A guy who is versatile, plays center, plays wing, plays both special teams, takes faceoffs."
He also has nine goals and 15 points in 27 Stanley Cup Playoff games, including seven goals and 11 points in 18 games during Carolina's run to the 2009 Eastern Conference Finals.
The Penguins are without forward Sidney Crosby for an indefinite period with a broken jaw.
"Obviously, getting healthy would leave different options available," Bylsma said. "You could see [Jokinen] playing on a fourth line and filling specific roles on your team, be it the faceoff or the power play. There are different options that he can fulfill at a point in time when you get everyone healthy."
