The J599 III series fiber optic connectors use a five-key circular identification positioning system. The five-key positioning system has blind insertion and anti-misinsertion functions, as well as vibration resistance. The connectors are made of 316L or aluminum alloy materials. They feature low loss, high reliability, and removable fiber components for easy on-site installation. The outer casing can be made of different materials and coatings to meet different environmental requirements.
