The J599 MPO fiber optic connector is based on the J599 circular fiber optic connector, utilizing a standard MPO fiber optic connector. The connector features a three-thread quick-connect design, along with a five-key positioning mechanism, offering blind-mate and anti-misinsertion capabilities, as well as vibration resistance. The connector is constructed from stainless steel 316L material, featuring high contact density and electromagnetic shielding functionality. The fiber optic components are removable, facilitating on-site installation. The connector has low insertion loss and high reliability, and is waterproof, dustproof, and corrosion-resistant. It is primarily used in marine vessel communication equipment, aircraft-mounted equipment, and harsh environments such as acidic, alkaline, hydrochloric acid, and humid conditions, as well as military communication and outdoor harsh environment communication applications. The connector is available in configurations ranging from 2 to 96 fibers.
