Amid the dual challenges of surging capacity demand and strict cost control in Data Center Interconnection (DCI) and metro networks, the market has long been calling for an optimal solution: a transmission scheme over tens of kilometers that delivers stable performance, controllable costs, and energy-efficient green operation all at once.
Accelink delivers a definitive answer with its live demonstration at OFC — the QSFP-DD 800G ZR Lite pluggable optical module. This is far more than a new product; it redefines the evolution path of economics and practicality for next-generation metro interconnection.
Today, the AI industry is evolving toward interconnection across multiple intelligent computing centers, with Scale Across technology emerging as the cornerstone for building supercomputing clusters. Against this backdrop, demand for high-speed interconnection between data centers is skyrocketing, and Scale Across interconnection applications impose more comprehensive requirements on the performance, cost, and power consumption of optical modules. Accelink's QSFP-DD 800G ZR Lite pluggable optical module is precisely developed to align with this trend.
The outstanding performance of the QSFP-DD 800G ZR Lite pluggable optical module stems from the deep synergy between Accelink's in-house developed silicon photonic chip and advanced streamlined Digital Signal Processor (DSP). Its core advantages are condensed into the "Two Lows and One Compact" feature set: low cost, low power consumption, and compact form factor. This not only precisely addresses the market's current dual demands for economic efficiency and practicality, but also fully fits the requirements of AI Scale Across interconnection application scenarios.
01 Low Cost
The in-house developed silicon photonic chip breaks through the cost barriers of key components. Combined with a streamlined coherent architecture, it significantly reduces the Total Cost of Ownership (TCO) of the module, making 800G high-speed medium-and long-haul interconnection affordable and clearing the obstacles for large-scale deployment.
02 Low Power Consumption
Compared with conventional 800G coherent modules, it achieves a power consumption reduction of over 20%. This not only translates to a lower Power Usage Effectiveness (PUE) for data centers, but also delivers a sharp drop in cooling costs and higher rack port density, marking a critical step toward green computing.
03 Compact Form Factor
Amid the trend of high-density equipment deployment in AI intelligent computing centers, the QSFP-DD packaged 800G ZR Lite optical module fully demonstrates its compact size advantage. It enables more port configurations in limited rack space, improves space utilization, provides robust support for the compact layout of Scale Across interconnection, and further cuts overall operating expenses (OPEX).
Looking back at Accelink's innovation journey, from the 400G CFP2 DCO that laid the foundation for long-haul transmission, to the 400G/800G ZR/ZR+ series that led the DCI wave, and the L-band solution that expanded spectral efficiency, we have consistently led the evolution of optical interconnection with our full-scenario product portfolio. The launch of the QSFP-DD 800G ZR Lite pluggable optical module once again demonstrates our strong comprehensive capabilities from cutting-edge technology to commercialization, delivering optimal solutions tailored to customers' diverse scenario and budget needs.
