The Cottagers are keen to get as many of their young professionals playing regular first team football as possible.
A number of U21 stars have been allowed to link up with lower league sides - with Dan Burn, Marcello Trotta, Marcus Bettinelli, Ryan Williams and Cauley Woodrow all heading out of Craven Cottage.
Jol would, however, like to give a few more players the kind of experience Pajtim Kasami got at Swiss outfit Lucerne last season and Omri Altman is getting in Israel with Maccabi Tel Aviv.
He said in the Fulham Chronicle: "My philosophy is it's always necessary for them to get games under their belts and to go on loan.
"We've got a lot of players in our U21s who could do well for lower league clubs - the only thing is I have to find the right clubs for them.
"Hopefully other managers in these leagues will know them and see them.
"They all want experience, so sometimes we have to go abroad."
