Above is the attenuation of the Ø100 µm core InF3 multimode fiber. The shaded region denotes the specified wavelength range over which the cable is guaranteed to meet attenuation specifications. The patch cable offers ≤0.45 dB/m attenuation (≥90% transmission over 1 m) from 2.0 to 4.6 µm, as denoted by the dotted line. For information on run-to-run variations, please see the Graphs tab.

Features

  • Hermetically Sealed Multimode Step-Index Fiber
    • Ø100 µm Core
    • InF3 for MIR (0.3 - 5.5 µm)
  • Construction Enables use at Vacuum Pressures Down to 1 x 10-8 Torr
  • Compatible with Visible-Wavelength Alignment Beams
  • Cleaned and Shipped in Double-Vacuum-Sealed Packaging

Our Vacuum-Compatible InF3 MIR Fiber Patch Cables are part of our vacuum-compatible product line and are designed to be used in high-vacuum environments at pressures as low as 10-8 Torr. The patch cable incorporates a hermetically sealed microtube containing 0.26 NA step-index multimode optical fiber in a Ø5.2 mm stainless steel interlock furcation tube. The InF3 multimode fiber features two SMA905 connectors on both sides of the cable. Both connectors are constructed using ARCAP, a copper, nickel, and zinc alloy that is useful for vacuum applications. The patch cable is double vacuum bagged to help prevent contamination when transported into a cleanroom environment. 

We also offer a KF40 flange fiber feedthrough that uses Ø100 µm InF3 multimode fiber (Item # VK4F1S). The MFV1L1 patch cable is compatible with this flange, and the two can be mated using a vacuum-compatible SMA mating sleeve, such as the ADASMAV.

This tab contains plots of the attenuation, numerical aperture, and refractive indices of our Ø100 µm core InF3 MIR multimode fluoride fiber as a function of wavelength.

The shaded regions in the plots below denote the specified wavelength range over which the cable is guaranteed to meet attenuation specifications. Our Ø100 µm InF3 patch cables offer ≤0.45 dB/m attenuation (≥90% transmission over 1 m) from 2.0 to 4.6 µm. Out-of-band performance is not rigorously monitored during quality control and may vary from run to run.

We are continuously refining our processes for these new materials in order to reduce the variations between runs.

This plot contains the measured attenuation from six independent draws of the Ø100 µm core InF3 fiber. The blue shaded region denotes the 2.0 - 4.6 µm range the attenuation is specified over. Within the 2.0 - 4.6 µm range, the attenuation is largely consistent from run to run, while greater variation between runs is observed in the visible and NIR.
