Fused Single Wavelength Singlemode 1X2 and 2X2 Fiber Optic Coupler/Optical Signal Splitter.

   Gould's singlemode Single Wavelength Fiber Optic 1X2 and 2X2 couplers and optical signal splitters are used to split light with minimal optical loss from one to two fibers or to combine light from two fibers into one fiber. These components are excellent for duplex transmission on a single fiber, CATV systems or within fiber optic test sets.
Features
  • Low Excess Loss (EL)
  • Low Optical Insertion Loss (IL)
  • Low Polarization Dependent Loss
Applications
  • Telecom
  • CATV Systems
  • Testing
  • Duplex Transmission
