WaveLogic 6 Extreme
There’s only one coherent 1.6 Tb/s
Optimize performance across any distance
WaveLogic™ 6 Extreme (WL6e) is purpose-built for high-capacity environments. Featuring industry-leading 1.6 Tb/s coherent technology and the ability to extend 800G across the longest network links, WL6e delivers exceptional reach and spectral efficiency. With WL6e, you can scale capacity, optimize footprint, and drive the lowest cost per bit across metro, long-haul, and submarine networks.
Features and benefits
-
Breakthrough 1.6 Tb/s capacity
Deliver highest-capacity connectivity, up to 1.6 Tb/s, to meet accelerating AI- and cloud-driven bandwidth demands with unprecedented scale
-
Double capacity, fewer transceivers
Transport twice the capacity per wavelength in existing 6500 and Waveserver® platforms, reducing transceiver counts while lowering cost and complexity
-
Ubiquitous 800G connectivity
Extend efficient 800G across the longest network links, including transpacific routes, to deliver global high-speed connectivity that sets your network apart
-
More value from every fiber
Streamline network design and extract maximum value from every fiber pair with advanced DSP algorithms that provide a 15% increase in spectral efficiency in a fraction of the footprint, optimizing C-band and C+L-band spectrum use
-
50% lower space and power per bit
Deliver at least double the capacity within the same power and space envelope—cutting watts per bit, reducing rack requirements, and supporting sustainability goals
-
Built-in, real-time network intelligence
Gain deeper visibility into network conditions with high-speed streaming telemetry for faster troubleshooting, improved resiliency, and smarter operations
