The J599 A8 series fiber optic connectors feature a three-thread quick-connect design with five-key positioning, offering blind-mate and anti-misinsertion functionality, as well as vibration resistance. The connectors are constructed from 316L stainless steel or aluminum alloy, ensuring low insertion loss and high reliability. The fiber optic components are removable, making on-site installation convenient. The product features waterproof, dustproof, and corrosion-resistant properties. Currently available specifications include: 2-core, 4-core, 6-core, and 8-core. Customization is also available upon customer request.
