While it was previously known that Ciena was going to be picked, AT&T confirmed that the vendor will be one of its domain suppliers for optical networking and transport gear.
Perhaps the only thing new here is that AT&T made an official announcement that Ciena is going to be its second optical domain vendor. AT&T, like many of its RBOC compatriots, tends to be a bit tight lipped about their vendor choices.
As suggested in a Light Reading article, Ciena became a favorite when it outbid Nokia Siemens Networks for Nortel Networks' Metro Ethernet Networks division. One of the things that made Nortel's MEN assets attractive to AT&T was its coherent 100 Gbps transport technology.
In the process, Ciena replaced Nokia Siemens Networks as one of AT&T's optical domain suppliers, while Fujitsu remains the second domain supplier.
