The floating pin termini provides exceptional low loss characteristics with high reliability and repeatability. They are designed to fit available formats of standard off the shelf electrical MIL-DTL-38999 cylindrical connectors (i.e D38999/20 & /26). The floating pin eliminates the need of using costly tight tolerance and hard to locate D38999/60 & /61 connector thus lowering the overall cost of ownership.

The floating pin termini will self-align into standard connector formats thus improving the fiber optic pin to socket alignment resulting in improved insertion loss performance with a .006" radial and 3.25 degree angular misalignment. The floating mechanism helps to ensure precision alignment of the fiber ferrules in extreme environmental conditions of shock and vibration.
