Product Description
The Neutral Water Tight expended beam Connector is a high-reliability, non-contact fiber optic connector designed for harsh and underwater environments.
Compliant with MIL-DTL-83526, it adopts a ball-lens beam expended beam structure, effectively reducing end-face contamination sensitivity and improving optical stability under repeated mating cycles.
The trapezoidal threaded coupling ensures secure, error-proof connection with excellent vibration and shock resistance, making it ideal for defense, marine, offshore, and other demanding applications requiring long service life and high sealing performance.
