偏振無關擾偏器 PS-700

偏振無關擾偏器 PS-700

FiberControl’s polarization-independent polarization state scrambler, PS-700, provides
high speed scrambling of optical signals with low insertion loss and is independent of the
input state-of-polarization. This robust all fiber design provides a wide optical bandwidth,
and enables the use of high signal powers, thereby making it suitable for DWDM

Our unique RF-modulated format provides near pseudo-random scrambling as indicated by
the broad RF electrical spectral response, unlike other scramblers, whose spectral response
reveals well-defined resonances. The high-speed scrambling provides coverage over a
large portion of the Poincaré sphere. Fully Patented.



  • Polarization independent
  • Broad optical bandwidth
  • High optical power throughput
  • Low back-reflection, low insertion loss
  • Connectorized or fiber input/output
  • Instant on (no warm-up)
  • Wide temperature range


  • Component level PDL measurements
  • Sub-system PDL testing
  • Reduce polarization-dependent effects
    within EDFA optical transmission systems
    (PDG, PDL)
  • Reduce PDL in test-bed measurements of
    third-party optical equipment
