WSP's Tap Power Monitors have the industry highest standards in regard to accuracy and long-term stability. They are designed to have the highest responsivity (R) for the tap signal and minimal insertion loss (IL) for the optical through signal. For PM fiber versions, our proprietary design and process preserve the input PM light with high polarization extinction ratio (PER). The selections for basically all types of fibers and connectors are available.
WSP's Tap Power Monitors have long been used in medical instrumentation, sensing and fiber laser industries.
WSP can provide customized designs to meet specialized applications.
