But Cardiff go into Sunday's meeting at the Liberty Stadium hoping to avoid losing both games in a season in the south Wales derby's 82-year history.
"I don't want to see that happen in my time," said on-loan Olofinjana.
"We will give our best towards making sure it stays the same."
Swansea beat Cardiff 1-0 in the November meeting at the Cardiff City Stadium thanks to on-loan striker Marvin Enmes' solo strike.
But both sides are very much in the hunt for automatic promotion to the Premier League with just 10 points separating the top six.
Swansea are currently a point behind second-placed Norwich City and six points behind leaders Queens Park Rangers.
Cardiff, last season's beaten Championship play-off finalists, are on 48 points so trail their Welsh neighbours by two points as they also battle for a place in the top two.
Brendan Rodgers' Swans have won three successive league matches at the Liberty Stadium without conceding a goal.
Dave Jones' men are unbeaten in four but have not won away since 13 November, and the Bluebirds travel to Swansea without a win in Wales' second city since 1997.
"As a team, I don't think we want to look at it as a derby, we want to look at it as one of the games we play in the season," said Olofinjana, who is on a season-long loan from Hull City.
"We know very well it's going to be a difficult game because of the attention the game is going to bring.
They are fantastic ball jugglers and very, very wonderful players, but they are beatable

"I've been privileged to have played in a few derbies and I know what to expect. The game itself is more for the fans.
"We try to tell ourselves to play the game not the occasion. It's a pride thing, a commanding thing, so you can understand the frustration if it doesn't go the way they want the game to go."
And Olofinjana knows Swansea will be ready for whatever the Bluebirds throw at them.
"I think they've got a very wonderful team. They pass the ball very well, they are set in their ways and they know what they want to do and they do it very, very well," he added.
"Without giving too much away, I would say they are the Chelsea of the division in the way they go about everything.
"They are fantastic ball jugglers and very, very wonderful players, but they are beatable."
