1X2(2X2) Polarization-maintaining Fiber Coupler
The 1x2 (2x2) polarization-maintaining fiber coupler fabricated by using special polarization-maintaining fiber and strong-fused tapering process can divide the polarized light into two beams with the same polarization state as the input light, and can support any splitting ratio as required. The product has passed GR-1209-CORE and GR-1221-CORE reliability tests and various military environmental assessment tests. Boasting stable performance and high reliability, the product has been applied in multiple national key projects.
  • High reliability
  • High extinction ratio
  • High impact resistance
  • Low additional loss
  • Good environmental stability
