Polarization Maintaining Fiber Optic PM DWDM Device for ICT AI Computing

Polarization Maintaining Fiber Optic PM DWDM Device
PM DWDM Device Overview
The In-line Polarizer is engineered to transmit light with one specific polarization while effectively blocking the other polarization with a high extinction ratio. This device delivers low loss, high extinction ratio, and exceptional return loss performance. It can also convert unpolarized light into polarized light with superior extinction ratio characteristics, selectively passing light along either the slow or fast axis while blocking the orthogonal polarization.
Key Features
  • Low Insertion Loss
  • High Return Loss
  • High Isolation
  • High Stability and Reliability
