AFR's MEMS Variable Optical Attenuator is based on an electrostatic drived micro-electro-mechanical-system (MEMS) chip. The MEMS Variable Optical Attenuator chip consists of a tilting mirror to change light coupling between input and output fibers. The components are characterized with low insertion loss, fast response and compact size. The MEMS Variable Optical Attenuator is widely uesd in WDM networks, power control or gain variation in EDFA.
Variable Optical Delay Line provides precision optical path variation of more than 15 cm (500 ps). The compact, rugged design makes the device ideal for integration in network equipment, test instruments, and optical for integration in network equipment, test instruments, and optical coherence tomography (OCT) systems for precision optical path length or timing alignment.
The 2 μm Fused Wavelength Division Multiplexer combines or separates light at 1570 nm (800 nm) and 2000 nm windows. They offer very low insertion loss and excellent environmental stability.
The PMFCM series is manufactured by using advanced technology to allow the input signal to be split into multiple channels at a given splitting ratio with high extinction ratio, low excess loss, good uniformity, low WDL and low TDL. It can be widely used in fiber sensors, amplifiers, various laser applications, etc.
