Product Profile
The High ER Polarization Maintaining Filter Coupler is a passive optical device that combines two or more optical signals into a single output. It can maintain the polarization of the input light signal and achieve low excess loss. This type of filter coupler is designed to work at specific wavelengths and can be customized to meet different coupling ratios and connector types.
OPTICO offers a range of high-quality High ER Polarization Maintaining Filter Coupler products, designed to deliver superior performance and reliability. Our couplers are ideal for a wide range of applications, from telecommunications and fiber optic sensors to test and measurement systems. Trust in OPTICO to provide the highest quality couplers that meet your specific needs.
Product Features
Low Insertion Loss: The High ER Polarization Maintaining Filter Coupler features low insertion loss as low as 0.3 dB by the use of high-quality materials and advanced manufacturing techniques, maintaining the performance of the device over time.
High Return Loss: Carefully manufactured to minimize any reflection or scattering of light, the coupler provides the minimum return loss up to 50dB.
High-Quality Signal
High PER: With a high PER, the device can effectively separate the polarized signal from the unpolarized signal, improving the overall signal quality and minimizing any signal degradation.
