Fiber Optic Isolators
Fiber Optic Isolators

  • Very low insertion loss, high isolation and high return loss
  • Minimal polarization dependent loss, and very low polarization mode dispersion
  • All models have an epoxy-free optical path, resulting in increased isolation performance, stability and long-term reliability
  • Compact lightweight assembly allows easy integration in small laboratory, field, and system applications
  • Fiber optic amplifiers
  • Fiber optic ring lasers
  • High-speed and coherent fiber optic communication systems
  • Fiber optic links in CATV applications

Product Description
Newport’s Fiber Optic Isolators are passive, fiber-pigtailed devices that reduce back reflections and backscattering of light (highly desirable in laser applications, for example).
Three models are available to meet your particular isolation requirements.
The standard ISC Model isolator features typical peak isolations of >40 dB and very low polarization mode dispersion.
The enhanced ISS Model and supreme ISU Model isolators feature extremely low polarization mode dispersion and stable performance over a wide wavelength and temperature range.
