Optical Fiber Coupler

Description

Neurotronix dual-wavelength Fused Bi-conical Taper splitter (FBT) 1×N star optical fiber splitter is the series connection of N-1 pieces of 1×2 splitter. The bandwidth of +/-40nm under 1310nm and 1550nm, or 1310nm and 1490nm makes the splitter meet the requirement of ratio accuracy under both the two wavelengths.

And it has feature of low additional loss and low polarization sensibility loss.

Features

  • Dual Broadband
  • Low loss
  • Low polarization sensibility loss.
  • Can resist the change of environment.

 

Applications

  • FTTP (FTTH, FTTO)
  • FTTB, FTTC, FTTN
  • HFC
