FBT Singlemode Tree and Star Fiber Couplers are used to distribute optical signals in the coupling area. Singlemode Tree and Star FBT coupler is operating bandwidth is expanding to 1310nm, 1490nm and 1550nm three communication windows. The FBT Tree and Star coupler has the same coupling ratio on 1310, 1490 and 1550nm communication windows, with low excess loss and low PDL.
