高端光学芯片、组件和模块的领先开发商JOONLAN宣布在全球推出其新的800G相干可插拔光学模块，旨在满足人工智能（AI）数据中心对高速、低延迟连接的激增需求。这些新模块采用OSFP/QSFP-DD外形尺寸，利用该公司专有的相干技术和先进的数字信号处理（DSP），在短距离和长距离链路上提供业界领先的性能。
“AI infrastructure is evolving at an unprecedented pace, with hyperscale data centers expanding across multiple sites to accommodate massive workloads,” said Dr. Li Wei, Chief Technology Officer at JOONLAN. “Our 800G coherent modules address the critical need for reliable, high-capacity interconnection between geographically dispersed compute clusters, while minimizing power consumption and operational costs.”
The new 800G modules support IP-over-DWDM architecture, enabling direct integration between routers and dense wavelength division multiplexing (DWDM) systems. This eliminates the need for intermediate transponder equipment, simplifying network design and reducing capital expenditures. With a target transmission reach of up to 120 km, the modules are ideal for data center interconnect (DCI) applications, as well as for metropolitan and long-haul transport networks.
主要特征包括：
超低功耗：与竞争对手的解决方案相比，优化的DSP和激光驱动器设计可将功耗降低20%，支持节能的AI数据中心运营。
High reliability: Built-in thermal management and error correction technologies ensure stable performance in high-density, high-temperature environments.
灵活部署：可插拔的外形便于集成到现有的网络基础设施中，向后兼容400G和100G系统。
JOONLAN reports that early trials with leading cloud service providers have shown consistent signal quality and latency performance, with the modules meeting or exceeding industry benchmarks for 800G coherent transmission. The company plans to begin volume shipments in Q3 2026, with production capacity scaling to meet demand from global data center operators.
