According to a Canadian Press report, Nokia Siemens Networks (NSN) has asked a US bankruptcy court to reject Ciena as the winning bidder for Nortel Networks’ optical networking and carrier Ethernet businesses and suggested it would be willing to pay more. NSN and its partner One Equity Partners said they would be willing to pay US$810 million in cash for the business, topping the US$530 million in cash plus US$239 million of convertible notes due June 2017 that made up Ciena’s winning bid.
