There have been rumours circulating about the Magpies' squad being divided, with suggestions that the club's sizeable French contingent is largely apathetic to the team's current Premier League plight.
The St James' Park outfit are lurking just three points above the drop zone and in serious danger of being relegated to the Championship.
But Cabaye told the Chronicle: "In the dressing room, everything is OK here.
"The French players all want to adapt well. We are all focused together.
"We have stayed focused on being safe and playing in the Premier League next season. That is the most important thing.
"We know we are going to play well if we are focused together and stay together."
Regarding the goalless draw at Upton Park on Saturday - following on from their 6-0 home defeat by Liverpool seven days earlier - Cabaye added: "I think we had a good response from last week but we did not win the game.
"It is going to be very important to get three points against QPR.
"It is only about us now, not Wigan, Norwich or anybody else."
