product description
An inline polarizer is an optical device specifically designed to control the polarization state of light. Its main function is to allow light with specific polarization directions to pass through while effectively blocking light with orthogonal polarization directions. This design enables the inline polarizer to convert non polarized or partially polarized light into polarized light with high extinction ratio, thus playing an important role in applications that require high polarization extinction ratio.
The application of inline polarizers is particularly important in high-speed communication systems and testing instruments, as the signal transmission quality in these systems often depends on the polarization characteristics of light. Here are some key characteristics and applications of inline polarizers:
High extinction ratio: Linear polarizers can provide high extinction ratio, which means they can effectively attenuate unwanted polarized light, improving signal quality and reliability. For example, the CUBE-ER100 polarization extinction ratio tester can measure polarization extinction ratios up to 52dB, making it suitable for fiber optic and free space optical applications
Low insertion loss: The inline polarizer is designed to minimize the loss of optical signals passing through, ensuring efficient signal transmission.
Excellent polarization properties: Linear polarizers utilize their excellent polarization properties to improve the extinction ratio of signals, which is crucial for precise polarization control and signal quality.
Environmental stability: Linear polarizers can maintain stable performance under various environmental conditions, which is particularly important for fiber lasers and testing instruments that need to operate in variable environments.
High power processing capability: The inline polarizer can withstand high-power optical signals, making it suitable for high-power fiber laser and instrument applications.
Wide operating temperature range: The inline polarizer can operate reliably within a temperature range of -5 ° C to+70 ° C, ensuring stable performance under different environmental conditions.
Customizable fiber types and connectors: Linear polarizers offer multiple fiber types (such as SMF-28 or Panda fiber) and connector types (such as FC, SC, LC, etc.) to meet different application needs.
Flexible coupling ratio options: Linear polarizers can provide different coupling ratios to accommodate different power allocation requirements.
These characteristics of inline polarizers make them an ideal choice for fiber lasers, fiber amplifiers, coherent communication systems, fiber optic gyroscopes, and other high-performance network applications. By precisely controlling the polarization state of light, an inline polarizer helps improve the overall performance and reliability of the system.
