Product Details

Single-Mode Star/Tree Coupler
●The Single-mode Optic-fiber Tree /Star Coupler can couple the optical signals in the coupling area, and then re-distribute the light power.
●The key parameters include center wavelength, bandwidth, and excess loss, coupling ratio, PDL and so on.
●All the optical fused couplers which employ FBT technique are proved to have high performance in applications.
