J599MT Series Fiber Optic Connector

The J599MT Series Fiber Optic Connector is a high-density, circular fiber optic connector developed on the GJB599Ⅲ platform and designed for harsh-environment applications. By adopting 12-core / 24-core MT fiber contacts, this series enables compact, high-channel-count optical transmission while maintaining excellent mechanical strength and environmental resistance.

With multi-level guidance, blind-mate capability, and anti-mis-insertion design, the J599MT Series ensures reliable performance in demanding defense, aerospace, aviation, and industrial communication systems.
