- Fiber laser combining or splitting for enhanced power
- Biomedical imaging systems
- Reflective sensor systems
PM Filter DWDM
PM Filter DWDM devices by SANWA use environmentally stable thin film filters and advanced packaging technology to achieve wide passband, low insertion loss, high channel isolation, excellent environmental stability, and high extinction ratio. They can be used individually to perform single-channel add or drop functions or can be used in DWDM systems and fiber sensor systems. SANWA's PM Filter DWDM is designed and manufactured according to Telcordia standards and ITU standards.
PM Filter Coupler
The SANWA Polarization Maintaining Filter Coupler is manufactured by using advanced technology to allow the input signal to be split at various ratios with a high extinction ratio. It supports both polarizations.
PM Filter Coupler Module
The PM Filter Coupler Module offered by SANWA is manufactured using advanced technology to allow the input signal to be split into multichannels at a given splitting ratio with a high extinction ratio, low excess loss, low uniformity, low WDL, and low TDL. It can be widely used in fiber sensors, amplifiers, lasers, etc.
PM Beam Combiner/Splitter
The SANWA Polarization Beam Combiner/Splitter is a compact, high-performance lightwave component that combines two orthogonal polarization signals into one output fiber. The most common application is to combine the light of two pump lasers into one single fiber to double the pump power in EDFA or Raman Amplifier. The device can also be used as a beam splitter.
PM Mini Optical Circulator
The SANWA Mini Fiber Optic Circulator is a compact, high-performance lightwave component that routes incoming signals from Port 1 to Port 2 and incoming Port 2 signals to Port 3. The component provides high isolation, low insertion loss, low PDL, low PMD, and excellent environmental stability. It is widely used in combination with fiber gratings and other reflective components in DWDM systems, high-speed systems, and bi-directional communication systems.
PM Isolator
The SANWA Polarization Maintaining Isolator is characterized by low insertion loss, high isolation, high return loss, high extinction ratio, and excellent environmental stability and reliability. It is ideal for polarization-maintaining fiber amplifiers, fiber lasers, high-speed communication systems, and instrumentation applications.
