1X3 Single-mode Fiber Coupler
1X3 single-mode fiber coupler is fabricated by using unique strong-fused tapering process, which is used for light splitting and light combining of the optical path and can divide the input light into three beams. 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
  • Small size
  • High impact resistance
  • Low additional loss
  • Good environmental stability
