The upgrades include new 40 Gigabit Ethernet (GbE) and 100GbE service interfaces. The DTN also can now be fitted with DWDM line-cards that support serial 40-Gbps coherent transport. Infinera demonstrated the 40-Gbps coherent capabilities last Thursday as part of its DTN-X demonstration. The company showed one of the DTN-X 500-Gbps superchannels running alongside a 40-Gbps wavelength generated by a DTN.
Infinera sources told Lightwave that the company already has orders for the 40-Gbps line card and expects to recognize revenue from them in the fourth quarter.
One upgrade that you won’t see on the DTN is the addition of the 500-Gbps photonic integrated circuit (PIC) at the heart of the DTN-X. The DTN’s backplane won’t support the capacity the 500G PIC enables, the Infinera sources said.
