Product Description
The J599Ⅲ Series Fiber Optic expended beam Connector is a military-grade, non-contact fiber optic connector designed for high-reliability optical transmission in harsh environments. Based on the GJB599B (MIL-DTL-38999) Series III interface, it adopts a beam expended beam (collimating lens) principle to significantly improve resistance to dust contamination and end-face damage. With robust mechanical performance, wide operating temperature range, and excellent environmental resistance, this connector is ideal for aerospace, aviation, naval, and other defense communication systems requiring stable and long-life optical interconnection.
Key Features
- Fits GJB599B (MIL-DTL-38999) Series III interface
