Nokia Siemens Networks says it has successfully demonstrated the operation of native 100-Gigabit Ethernet optical interface interoperability between its hiT 7300 DWDM platform and Juniper Network’s T1600 core router. The trial, conducted at Nokia Siemens Networks’ ResIP Center in Munich, Germany, comes in advance of the commercial roll out of 100-Gbps capabilities on the hiT 7300, now scheduled for the middle of this year.
Pathmal Gunawardana, head of optical networks for North America, Nokia Siemens Networks, referred questions regarding details of the optical interface used in the interoperability demonstration to Juniper, but stressed that the interface offered native 100-Gigabit Ethernet operation.
Meanwhile, on the line side, Nokia Siemens Networks was known to be working with CoreOptics on coherent 100-Gbps serial transmission technology before Cisco purchased the latter. Gunawardana dodged questions regarding its current 100-Gbps technology suppliers, but said that the company had invested a significant amount of money in developing in-house capabilities as a way to keep its options open. He also noted that the number of companies capable of supplying 100-Gbps components, particularly ASICs and DSPs, had grown considerably since the company first began work on its 100G nice cards. Nokia Siemens Networks will demonstrate operation of a prototype 100-Gbps coherent circuit pack at OFC/NFOEC next week, Gunawardana revealed.
The interoperability announcement comes a day after Juniper announced its PTX Series Packet Transport Switch (see “PTX Series Packet Transport Switch starts Juniper Networks down packet-optical transport path”). Gunawardana declined to comment on the Juniper announcement, including whether a PTX platform with fully integrated OTN optics would offer an alternative to the platform pairing that formed the basis of the interoperability demonstration.
