FiberPro PS-155A Fiber Optic Polarization Scramble

The FiberPro PS-155A Fiber Optic Polarization Scrambler manages and controls polarization state in fiber optic systems operating at 1550 nm. It deliberately varies the input optical signal’s polarization to eliminate polarization-dependent effects, enabling accurate testing and characterization of optical components. The instrument minimizes Polarization Dependent Loss (PDL) in devices and Polarization Dependent Gain (PDG) in amplifiers, ensuring reliable performance evaluation across optical communications, sensing, and component manufacturing.
