Infinera has unveiled a metro edge packet-optical platform that it says is optimized for bandwidth-intensive cloud-scale applications at the metro edge such as remote PHY, 5G transport and data center interconnect (DCI).

Infinera says the XTM II platform can provide rich Layer 0, Layer 1 and Layer 2 services with high density, low latency and low power consumption for facilities with restricted space and power.

Infinera says the new platform is backwards-compatible to its existing XTM Series chassis and adds new capabilities to the series, including 200 Gbps per wavelength, an eightfold density increase and a reduction in power per gigabit of 3.5 times. The company claims the new portfolio delivers what may be the lowest power consumption in the industry for 100/200G transport, while retaining very high density and low latency for high-performance applications.

The XTM II also features Infinera Instant Bandwidth, an open flexible grid line system and SDN control to give network operators a flexible, open and software-programmable packet-optical solution for Layer 0, Layer 1 and Layer 2 services.

“Service providers are moving packet intelligence closer to the edge of the transport network to support high-capacity and low-latency applications like the remote PHY requirements of cable MSOs,” said Andrew Schmitt, founder and lead analyst at Cignal AI. “The Infinera XTM II supports metro packet-optical applications with WDM uplink speeds up to 200G, while maintaining support for the installed base and the wider XTM Series.”

The new range of 200G-per-wavelength traffic units includes a 400G “flexponder” (a dual 200G muxponder that uses 16QAM for high-capacity transport, or a dual 100G transponder that uses QPSK for longer reach operation),a 200G Layer 1 muxponder that supports a broad range of client signals, and the EMXP440 packet-optical transport switch that provides Layer 2 packet-optical switching with dual 100/200G ports and 12 or 24 10G ports.

The XTM II chassis are already shipping to customers and the 400G Flexponder will be available in Q3, with additional components of XTM II available by the end of 2017.
