Fiber Optic Couplers

    The single mode single window coupler employs bandwidth-extending technology to extend bandwidth up to  +/-40nm at 1310/1550nm channels. Within this broad range, the accurate coupling ratio can  be obtained. Moreover, this kind of coupler can satisfy the requirements of low excess  loss, low PDL, etc. Single-mode single window couplers have already been widely used for  broadband light source, test instruments and broadband optic fiber networks.
