Bring a large pot of water to boil, add fettuccine noodles and return water to boil. Cook until noodles are al dente. Drain well.
Meanwhile, in a large skillet, melt butter over medium heat, add shrimp and cook about 3 minutes, until shrimp turn pink. Remove shrimp from heat and set aside.
Pour wine and lime juice into the skillet used to cook the shrimp. Bring the mixture to a boil. Boil until the mixture is reduced by half, about 2 minutes. Return shrimp to skillet. Add cilantro, cayenne pepper and salt and pepper. Stir to heat the mixture through, about 2 minutes. Toss with pasta and serve.
