This product measures “polarization extinction ratio” and”“misalignment angle of polarization maintaining axis orientation and its connector key orientation” of PMF patch cords with connectors by inserting the cords into the optical adapter parts. This design enables very reproducible and highly precise monitoring and evaluations. 

Polarization of thin LD modules can be evaluated and optical devices can be assembled (polarization axis adjustment) using excitation units (option). 

* In addition, special orders for fiber array, external units, other wavelength, etc. are also accepted.
