Low Loss Floating Fiber

For MIL-DTL-38999 Style Connectors

Smiths Interconnect's floating pin termini provide 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). 

  • Floating design (< -0.5dB)
  • Low loss fiber
  • Vibration resistant
  • 38999 Size 16 contact platform compliant

Features & Benefits

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.

  • Floating design (< -0.5dB), low loss fiber
  • Vibration resistant
  • Precision floating ceramic ferrules
  • Stainless steel terminus body
  • Designed for use in size 16 cavities of the D38999 Series III connector
