Product Description
The J599E6 Series Expanded Beam Fiber Optic Connector is designed with an interface fully compliant with GJB599B (MIL-DTL-38999 Series III) and optical performance meeting ARINC 801 requirements.
By adopting expanded beam lens technology and non-contact optical mating, the connector delivers exceptional durability, contamination tolerance, and long service life, making it ideal for harsh and mission-critical environments.
Key Features
- Interface compatible with GJB599B / MIL-DTL-38999 Series III, ensuring seamless system integration
- Optical performance compliant with ARINC 801 standards
- Expanded beam lens design with non-contact optical coupling, eliminating end-face wear
- Sealed ceramic ferrule with O-ring structure, significantly extending mating cycles
- High resistance to dust, contamination, and harsh environments due to expanded beam technology
- Easy installation and removal using standard contact tool M81969/14-03
- Ideal for avionics, defense, aerospace, and ruggedized optical systems
