JOONLAN has unveiled its new line of silicon photonics-based 400G optical engines, developed in collaboration with leading semiconductor foundries. The integrated engines combine photonic integrated circuits (PICs) with electronic components on a single chip, delivering high-speed, energy-efficient connectivity for data center switches and servers.
“Silicon photonics is the future of optical communication, enabling unprecedented levels of integration and cost reduction,” said Dr. Chen Hao, Director of R&D at JOONLAN. “Our 400G engines leverage mature silicon manufacturing processes to deliver performance comparable to discrete optical modules, but with a smaller form factor and lower power consumption.”
The new engines feature a through-glass-via (TGV) packaging design, which minimizes signal loss and improves thermal management. They support up to 400Gbps per lane, with options for parallel (DR4) and single-mode (LR4) transmission, making them suitable for both intra- and inter-rack data center connections. The engines are fully compatible with mainstream network equipment from vendors including Cisco, H3C, and Huawei.
Key advantages include:
- High density: The compact design allows for 25% more ports per rack, improving space utilization in high-density data centers.
- Low power: Integrated photonics reduces power consumption by 30% compared to traditional 400G modules, supporting lower cooling costs and reduced carbon footprint.
- Scalability: The modular architecture enables easy upgrades to 800G and beyond, providing a clear path for data center operators to scale their networks.
JOONLAN has already secured initial orders from several hyperscale data center operators, with shipments scheduled to begin in Q2 2026. The company plans to expand its silicon photonics product line to include 800G and 1.6T engines by 2027, further strengthening its position as a leading provider of next-generation optical solutions.
