NS-type Polarization Scrambler Module
The NS-type Polarization Scrambler Module by Photonwares Corp. is a fully integrated module that scrambles the polarization of input light. It is finely-tuned at room temperature before shipment to ensure the Degree of Polarization (DOP) specified in the datasheet is met for all input polarization states. The module has a power supply connector (12V), a polarization scrambler, an optical input, and an optical output.
Introduction
The NS-type fiber-optic polarization scrambler (NOPS) is based on a high-speed
electro-optical (EO) material plate functioning as a phase retarder. Three EO
plates are oriented at 0, 45, and 0 degrees, respectively. The three EO plates
are driven at three different sinusoidal waves that are not synchronized. The
driving board internally produces the sinusoidal waves. NOPS has three
versions currently, of which the maximum frequency is 5MHz, 2MHz, and 300kHz,
respectively. Figure 1 shows the OEM type of NOPS on the driver.

Product Usage Instructions
- Connect the 12VDC power supply to the DC port #1 of the module.
- Connect the optical input to the input port of the module.
- Connect the optical output to the output port of the module.
- The module will automatically scramble the polarization of input light.
The instrument type of NOPS is currently available only for the 300kHz version, as shown in Figure 2, where the NOPS is packaged in one enclosure to minimize the external impact on the DOP performance.
The NOPS is delivered with one 12VDC power supply.
Operation
This NOPS is a fully integrated module and ready to use. The user only needs
to plug the power supply into DC port #1, as shown in Figure 1, the NOPS will
automatically scramble the polarization of input light.
Performance
The performance of NOPS is finely-tuned at room temperature before shipment to
ensure the DOP specified in the datasheet is met for all input polarization
states. So, please don’t change any pre-setting on the driving board.
Figure 3 shows the setup for a fine-tuning process by using a polarization
controller (PC) and polarization analyzer.
Figure 4 shows one example measurement using an HP polarization analyzer.
