12F ELSFP Testing Cable is a single-sided fiber optic test assembly designed for external laser source interconnect testing in CPO and NPO architectures. Featuring a compact ELSFP interface with a 12-fiber MT ferrule, it enables reliable mating with the corresponding host-side optical connector for test, validation, and system integration.
Precision Interface
Designed for high-precision ELSFP optical connectivity, supporting stable and repeatable test connections in advanced external-laser architectures.
12-Fiber MT Design
A single-sided 12F configuration supports compact fiber routing and efficient connection to ELSFP host interfaces.
