In November Andre van Deventer was convicted of assault and crimen injuria, after an argument with 50-year-old Gloria Kente in 2013.
Kente previously told the court that he grabbed her pyjamas, verbally assaulted her and spat in her face.
Van Deventer admitted to the crimen injuria charge, but denied assaulting her.
After his last court appearance on December 12, Van Deventer told Kente that he planned to apologise to her in person at his next appearance.
Prosecutor Andy Hess previously suggested community service be imposed, with a possible placement in the African National Congress Women's League, arguing that this would be a way for Van Deventer to learn to get along with women and black people.
Testifying in mitigation of sentence, Van Deventer said he had written a letter of apology to Kente and had apologised on national television.
"I have been attacked from all sides because of this case and it has had a huge impact on my life," he said.
The Cape Town Equality Court, in a separate case involving the same incident, ruled on October 24 that Van Deventer pay Kente R50 000 in compensation.
