This　paper　investigates　entanglement　between　two　atoms　in　two　distant　cavities,　which　are　connected　by　an　optical　fiber.　We　give　an　exact　expression　of　the　evolution　of　the　whole　system,　and　study　the　entanglement　between　the　two　atoms.　We　find　that　even　the　fiber-cavity　coupling　constant　is　smaller　than　the　atom-cavity　coupling　constant,　high　degree　entanglement　between　the　two　atoms　is　obtainable.　This　result　gives　a　new　prospect　for　experimental　realization.　©　2009　Elsevier　B.V.　All　rights　reserved.
