1X2(2X2) Single-mode Fiber Coupler
The 1x2 (2x2) single-mode fiber coupler fabricated by using single-mode fiber and strong-fused tapering process can divide the input light into two identical beams, 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
