Huawei Shows 400G and Peta-bit Cross-Connect

At this week's OFC/NFOEC 2012 Conference in Los Angeles, Huawei is showcasing ultra long-haul (UHL) 100G optical transport, next gen 400G, and its Petabit Cross-Connect technology.

Some highlights:

100G Coherent Solutions with Hard-Decision Forward Error Correction (HD-FEC) and improved performance Soft-Decision Forward Error Correction (SD-FEC) for high-capacity, Ultra Long-Haul (ULH) applications;
Next-generation 400G technology providing a sneak-peek at what is on the horizon for improving spectral efficiency by unlocking higher bit-rate capacities beyond 100G;

Petabit/s Photonic Cross-Connect (PPXC) technology utilizing a scalable, high-capacity switching architecture for management of 100G+ wavelengths at large add/drop sites of the future.

Following its successful ULH transmission of 100G coherent solutions across 3,000km of Corning SMF-28 ULL optical fiber (an ultra-low-loss ITU-T G.652-compliant optical fiber) in the fall of 2011, Huawei is demonstrating its second-generation 100G solution, a single wavelength, Optical Interoperability Forum (OIF) compliant technology utilizing SD-FEC which improves 100G system reach up to 30 percent.

Huawei is also highlighting its first-generation 400G technology utilizing Orthogonal Frequency Division Multiplexing (OFDM) Polarization Division Multiplexing-16 Quadrature Amplitude Modulation (PDM-16QAM), enabling up to 16 Tbps of capacity at 100 GHz spacing or 21 Tbps of fiber capacity by removing guard bands with flex-grid technology.
