The 26 year old Swedish international had been linked with a move to the Liberty Stadium over the summer but the deal was blocked by the Canaries.
Swans boss Garry Monk will look to make good use of the £25m funds accrued from the sale of Wilfried Bony to Man City and will offer Olsson the chance to return to the top flight.
The attack minded full-back six years at Blackburn Rovers before moving to Carrow Road in July 2013 but was unable to prevent his side suffering relegation to the Championship in his first season at the club.
Without a win in four games Monk will be keen to acquire new talents this month so as to keep his side in the top half of the table and one imagines the South Wales side would look to sign a striker to make up for the loss of Bony.
