The decision came after it became clear that Nortel's latest strategy of selling off key parts of its business meant it would not be able to honour the contract with LOCOG - the Games' organising committee - which spanned Nortel's entire portfolio.
London 2012 CEO Paul Deighton explained: "We continue on a path to deliver the most connected Games possible. We part with Nortel on good terms.
"Nortel acknowledges our fixed deadlines and our desire to have a single supplier for our entire network infrastructure have been impacted by Nortel's decision to move towards standalone businesses," said Deighton.
He added its decision was not a reflection of the vendor's capabilities, "this is all about meeting our fixed deadlines."
LOCOG invited Cisco to bid for the contract in late June, and a deal was officially struck on Friday to make the networking giant the official network supplier to London 2012.
"We are delighted to be working with LOCOG to provide the network infrastructure for London 2012," said a diplomatic Phil Smith, Cisco UK and Ireland boss
"In the UK, Cisco enables businesses, public services and ultimately communities to enhance the way they operate. We will work hard to deliver the infrastructure for London 2012, which promises to be the most connected Games ever," he added.
Nortel did not provide comment.
