ADVA Optical Networking is using Xelerated’s X11 network processor unit (NPU) in the ADVA FSP 3000 Wavelength Division Multiplexing (WDM) system, which enables service providers to extend Carrier Ethernet services into fiber access and aggregation networks. 
The X11’s architecture guarantees deterministic, low latency packet behavior, regardless of packet size, traffic pattern or number of instructions used per packet.

From the Technology Graveyard
You just read about Carrier Ethernet. Here is what it replaced:
Resilient Packet Ring (RPR) served 2004–2010. What ultimately replaced it?
Resilient Packet Ring (RPR) a dual counter-rotating fiber ring with a fairness MAC that shared bandwidth statistically and healed in under 50 ms - SONET-grade resilience with packet efficiency. Its job passed to Carrier Ethernet — but the problem it solved, and the ideas it proved, live on in what replaced it. The standard rests here in the archive. One of 198 technologies here that opened a door and then held it for the next.
