AFR's MEMS Optical Switch is based on an electrostatic drived micro-electro-mechanical-system (MEMS) chip. The MEMS chip consists of a tilting mirror to change light coupling between input and output fibers.The components are characterized with low insertion loss, high return loss, excellent environmental stability and reliability. The optical swtich has been widely used in fiber optics communication equipment, fiber instruments, and fiber sensing to switch channels.
The Polarization Maintaining Tap Coupler is manufactured by using advanced technology to allow the input signal to be split at various ratios with high extinction ratio.
Mini Type Manual Variable Optical Attenuator (MVOA) operates by manually moving a shading element into optical beam. The shading element can be integrated and adjusted to get any attenuation value in a range. MVOA features low insertion loss, good resolution, high stability and good reliability. The Manual Variable Optical Attenuator applies for pre-emphasis attenuation, transmitter power control, in-line power equalization, and amplifier power control, etc.
The Mini Polarization Insensitive Isolator series is characterized with very compact package, low insertion loss, high isolation, high return loss and excellent environmental stability and reliability. This optical isolator is specifically designed to help engineers cope with smaller module designs or more components that need to fit into a module/linecard for highly integrated system requirements.
The Isolator Polarization Beam Combiner/Splitter is a compact device that provides both polarization beam combining and optical isolation in one integrated component. 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 Isolator Polarization Beam Combiner/Splitter has extremely low insertion loss, and it can improve the amplifier performance.
