ELSFP

Reliable optical power delivery for CPO / High-density, compact pluggable design / Compatible with PM and single-mode fiber / Designed to minimize high-speed PCB signal-path losses / Supports up to two 12-fiber MT interfaces.

Amphenol ELSFP (External Laser Small Form Factor Pluggable) interconnect solutions provide reliable optical power delivery from external laser sources to co-packaged optics (CPO) engines. The compact, serviceable interface supports PM and single-mode fiber with up to two 12-fiber MT ferrules. Designed for high-density AI, data center, and networking systems, the ELSFP architecture supports OIF-compliant connectivity and up to 100 connector/ cage mating cycles for scalable, field-serviceable optical systems.

OIF-defined ELSFP interface architecture / Up to two 12-fiber MT ferrules per interface / Up to 12 optical fibers per MT ferrule / PM and single-mode fiber configurations / Precision rotational alignment for PM fibers / Front- or rear-panel optical connectivity / Blind-mate pluggable optical interface / Defined electrical, thermal and mechanical interface
