Operating on a +5V DC supply with TTL control, it utilizes an all-fiber design for low insertion loss and interfaces via fiber pigtails with standard connectors. The device is used to mitigate Polarization Dependent Gain (PDG) in optical amplifiers, reduce PDL-induced fluctuations in fiber sensors, and for component characterization by averaging polarization effects in test and measurement systems. ## Function Scrambles the state of polarization (SOP) of an input optical signal over time. Utilizes high-speed polarization control to randomize the SOP, minimizing polarization-dependent effects in fiber optic systems. Accepts single-mode fiber input and output, operating at specified wavelengths with adjustable scrambling rates and polarization extinction ratio. ## Platform Designed for integration in fiber optic systems, this polarization scrambler operates over standard single-mode fiber interfaces with FC/APC or SC connectors. It is compatible with optical communication test setups and polarization-sensitive measurement instruments, controlled via USB or serial interfaces for real-time polarization state management. Typical applications include testing polarization-dependent devices, simulating polarization mode dispersion in telecom networks, and enhancing system robustness in coherent optical transmission environments. ## Application Designed for optical test systems and network conditioning, this device performs rapid and uniform polarization scrambling to randomize instantaneous polarization states, reducing polarization-related impairments such as polarization dependent loss (PDL), polarization mode dispersion (PMD), and polarization dependent gain (PDG). It facilitates characterization of optical components and systems by enabling PMD emulation, PDL measurement, and elimination of polarization sensitivity in high-speed fiber optic communication environments. Its all-fiber construction ensures minimal insertion loss, low back reflection, and negligible residual phase and amplitude modulation, suitable for lab automation and remote operation via digital interfaces. ## Accessories Four fiber optic connectors (FC/PC standard, FC/APC or SC optional), USB 2.0 Type-B connector for computer control, DB-9 RS-232 serial interface, 5V DC power input jack (2.1mm center positive), external 100-240VAC 50/60Hz switching power adapter included, LabVIEW drivers and GUI software provided, optional rack mount kit for 19" standard equipment rack, TTL trigger input/output BNC connectors for synchronization, front panel LCD display with menu navigation buttons, rear panel SMA connectors for analog control voltage inputs (0-5V) on each polarization channel ## Interface **Interfaces:** Single-mode fiber input/output via FC/PC connectors. TTL trigger input via BNC connector for external synchronization. RS-232 serial interface via 9-pin D-sub connector for remote control and configuration. DC power input via standard barrel connector accepting 12V external power supply. Optical return loss >50dB, insertion loss <0.5dB typical. ## Images - - - - -
