The Three Window FBT Coupler employs bandwidth extending techniques to change the wavelength and to make the coupler meet the requirement of light wave accurate distribution in 3 windows. 

The single mode Three Window FBT Couplers are used to "combine 3 networks together", they can realize 2-way transmission of 2 / 3 waves by 1 single optical fiber. 

Also, customers can specify your required coupling ratios for this Three Window Splitter. FC/UPC or APC, SC/UPC or APC, LC/UPC or APC and ST/UPC or APC fiber optic connectors are available.
