Additional information

  • Wavelength selection available. Visit Special Selection category for online selection from stock or contact us for more options.
  • Key-aligned connector will has its key aligned to slow axis of the PM fiber and the direction of polarization of the laser output. For connector not specified to be key aligned, the key will be in arbitrary angle with the polarization of the laser output
