Optical Fiber Feedthroughs

Product catalog summary
Overview: The document provides technical specifications and features of optical fiber feedthroughs designed for vacuum applications, compatible with FC/APC or FC/PC connectors.
Specifications:
  • Insertion Loss: Low insertion loss with specific values for singlemode and multimode fibers. Singlemode fibers have an insertion loss of less than 0.5 dB for SM1310 and less than 1 dB for SM633, SM780, SM850. Multimode fibers have an insertion loss of less than 0.5 dB.
  • Fiber Types: Various singlemode and multimode fibers are available with specific mode field diameters and numerical apertures (NA).
  • Materials: Housing is made of stainless steel 1.4404 (316L), and ferrules are made of ceramic (ZrO2).
  • Flange Systems: Compatible with KF, CF, and QCF flange systems.
  • Bakeout Temperature: Ranges from 180 °C to 250 °C depending on the product.
  • Helium Leak Rate: Less than 1 x 10-10 mbar l/s, ensuring UHV compatibility.
Accessories:
  • Optical fiber cables are available in any length for use on the atmosphere or UHV side.
  • Bolt-style feedthroughs are ideal for easy replacement in high-vacuum applications.
  • Custom-made optical fiber feedthroughs are available, including CF flange with 9 feedthroughs, with other designs available upon request.
