Employees of Germany's biggest cable operator, Kabel Deutschland, are pictured at the server room at the Kabel Deutschland playout center in Frankfurt February 25, 2013. Kabel Deutschland is to hike its dividend 67 percent in a move which some traders and investors saw as a first defensive jab to ward off a possible 10 billion euros ($13.4 billion) bid from Vodafone.
