A Sydney technician who stole explicit photos off multiple women's phones while connecting their homes to the NBN has been spared time behind bars.

Aydin Agar was given a 16-month jail sentence at Downing Centre Local Court on Monday but will serve it in the community by way of an intensive correction order.

The 25-year-old sent himself more than 80 images - some naked, some topless and others with lingerie - and a video of a sexual act from four women's phones while working as an NBN sub-contractor in 2017.

He told them he needed access to their devices to connect them to Wi-Fi and then accessed their image galleries.
