Lumentum to Showcase DWDM ELSFP Laser Module for AI Data Centers at ECOC 2026
Event summary
- Lumentum will demonstrate an eight-wavelength DWDM ELSFP laser module at ECOC 2026 in Málaga, Spain.
- The module targets OCI MSA requirements for co-packaged optics (CPO) and near-packaged optics (NPO) architectures.
- The module offers up to 24 dBm (~250 mW) of optical output power per wavelength with 12 W power consumption.
- Lumentum expects initial availability of the module in the first half of 2027.
The big picture
Lumentum's demonstration underscores the shift toward CPO and NPO architectures in AI-driven data centers, where compact, standards-based laser sources are critical. The module's design aligns with the OCI MSA, positioning Lumentum to capitalize on the growing need for high-bandwidth, low-power optical solutions. This move reflects broader industry trends toward energy-efficient, scalable connectivity for AI infrastructure.
