Polarization Controllers and Scramblers
Frequently Asked Questions
A fiber optic polarization controller is a device that allows for the control and adjustment of the polarization of light traveling through a fiber optic cable. This is important for applications such as telecommunications, where polarization can affect signal quality.
A fiber optic polarization scrambler is a device that randomly changes the polarization of light traveling through a fiber optic cable. This is useful for testing and characterization of fiber optic components and systems, as it simulates real-world conditions where the polarization of light can be random.
The use of a fiber optic polarization controller or scrambler can improve the quality and reliability of fiber optic communications by ensuring that the polarization of light is controlled or randomized as needed. This can reduce signal degradation and improve overall system performance.
Factors to consider when choosing a fiber optic polarization controller or scrambler include the wavelength range of the device, the polarization mode dispersion (PMD) performance, the insertion loss, the polarization extinction ratio (PER), and the repeatability and stability of the device.
In telecommunications, fiber optic polarization controllers are used to ensure that the polarization of light is aligned with the polarization axis of the receiving equipment, which can improve signal quality and reduce noise. Fiber optic polarization scramblers are used for testing and characterization of fiber optic components and systems, as well as for simulating real-world conditions where the polarization of light can be unpredictable.
Fiber optic polarization controllers and scramblers have a wide range of applications beyond telecommunications, including in optical sensing, optical microscopy, and quantum optics.
The cost of fiber optic polarization controllers and scramblers will vary depending on the specific device and its features. Basic devices can cost several hundred dollars, while more advanced devices with higher performance specifications can cost several thousand dollars.
