J599Ⅲ Series Expanded Beam Fiber Optic Connector

The J599 III series expanded beam fiber optic connector produced by Gigac Technology is a high-performance circular aviation connector designed for demanding military, aerospace, and industrial applications. This connector offers exceptional durability and reliability in harsh environments, ensuring secure and stable optical data transmission under extreme conditions.

Key Features:

• Standard-Compliant Interface: Fully complies with the GJB599B (MIL-DTL-38999) Series Ⅲ interface standard, ensuring broad compatibility and proven performance in critical systems.

• Configurable Environmental Protection: The outer shell can be customized with different materials and coatings to meet specific environmental needs—including corrosion, moisture, and chemical resistance.

• Quick-Lock Coupling Mechanism: Features a rapid three-start thread connection with an anti-loosening design, enabling fast and secure mating even in high-vibration settings.

• Error-Proof Blind Mating: The five-key polarization mechanism ensures correct alignment and prevents misplugging, supporting reliable connections in blind or restricted-access applications.

• Expanded Beam Non-Contact Technology: Incorporates collimating lenses to eliminate physical contact between fiber end faces. The expanded beam profile significantly reduces sensitivity to dust, scratches, and contaminants while enhancing mechanical longevity.

• High Durability: Designed to withstand repeated mating cycles with robust performance under mechanical stress.
