Kyocera provides RF absorber lids for fiber-optic communication modules.

  • Outgas-free ceramic RF absorber
  • Solution to cavity resonance and electromagnetic interference (EMI) noise in the cavity
  • Recommended for modules operating at 40Gbps or higher
  • Hermetically sealable lids are available (see photo at left).
    RF absorber is bonded onto the metal lid.

  • Kyocera's RF absorber lid solves cavity resonance in this example. Reference video showing actual "before and after" measurements is available in our Web Presentations.
