Fiber Optic Feedthroughs

MPF Optical Fiber Feedthroughs are designed for ultrahigh vacuum applications and feature extremely low outgassing rates and excellent helium leak rates. The feedthroughs are designed to mate with industry standard connectors (FC/PC, FC/APC, and FSMA).This allows for high transmission and minimal insertion loss at interconnects. You can purchase them as weldable or in CF’s or KF designs. We offer four fibers in single mode and four fibers with broader range frequencies (multimode).

Overall Technical Features:

  • Operating temperature: -25 to 75C
  • Bakeout temperature: 180C
  • Leak Rate: < 1x10 -9 am-cc/sec (He)
  • Installation: Weld, CF, KF, custom plates
