The 12F AR-Coated SN-MT Testing Cable is a high-density fiber optic test assembly designed for stable and repeatable testing of SN-MT interfaces. Its AR-coated optical end-face helps reduce Fresnel reflection at the test interface, minimizing reflection-related variation and supporting more consistent measurement results during repeated test cycles.

Designed for optical module validation, production-line testing, master reference connections, and optical test-link optimization, the cable supports high-speed parallel-optics environments, including 400G, 800G, and 1.6T applications. Fiber type, connector configuration, polarity, cable length, and other parameters can be customized to match different test systems and devices under test.
