Fulton has slipped down the pecking order at the Liberty Stadium and wants more competitive action with the chances at the Swans seemingly limited.
There were high hopes for Fulton this season but it seems unlikely he will see much action with the form of the Swans current midfield and the likes of Leon Britton and Matt Grimes also ahead of him waiting for their own chance.
Former Falkirk youngster Fulton joins Oldham, who are currently under the guidance of caretaker boss David Dunn, on a deal which runs until December 19.
He will team up with former Swansea colleague Dai Cornell at Boundary Park.
