External Laser Small Form Pluggable (ELSFP) is an external laser source architecture that complements and extends CPO deployments, enabling improved thermal management, serviceability, and flexible laser placement in high-density systems.
In ELSFP-based architectures, precise optical interfaces and reliable laser sources are essential for efficiently coupling laser output into optical fibers while maintaining low loss, stable polarization, and consistent performance.
Focuslight provides specialized aspherical micro-lenses optimized for LD-to-fiber coupling, along with high-performance substrate materials for laser integration and packaging, supporting efficient and reliable external laser modules for CPO applications.
