NSN thinks it has a place in AT&T's optical plans

Nokia Siemens Networks (NSN) may have lost its spot on AT&T's domain supplier list, but the vendor is confident that it will get a seat at the carrier's optical network table.

Right now, the only vendors that have been officially named as AT&T's domain suppliers have been Fujitsu Network Communications and Ciena. Being on this domain list, means that Ciena and Fujitsu will be the vendors that AT&T will use in upcoming optical networking builds. 

According to a Light Reading article, Fujitsu was apparently a shoe-in, while Ciena replaced NSN because it was able to successfully purchase Nortel's Metro Ethernet Network (MEN) assets.   

Oliver Jahreis, head of DWDM product management at Nokia Siemens Networks, argues that it still has a chance to get AT&T's business because of its experience in 40 Gbps systems based on differential shift keying (DPSK) modulation which the carrier is currently using on its network.

"What is important for a big carrier is whether something fits into their operating system landscape," Jahreis said. "Out of our installed base, I think there's still opportunity open for us."
