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.
The Fiber Optic Tunable Filter is based on fiber Fabry-Perot interferometer technology. Activated by a piezoelectric transducer, the device can be tuned across the entire C + L band. It is ideal for applications in signal selection, noise rejection, and spectrum analysis. Two thermistors are mounted in the filter package for temperature monitoring.
AFR provides Hermetic Fiber Feedthrough by hermetically attaching gold plated metal ferrule to fiber cables base on different applications to guarantee excellent hermetic feedthrough performance. SM, MM, PM individual fiber or ribbon fiber available upon request. The hermetic feedthrough is commonly used in PLC module, LD packaging and integrated optics packaging for hermetic sealing purpose.
The 2 × 2 Polarization Maintaining Optical Circulator is a compact, high performance lightwave component that routes incoming signals from Port 1 to Port 2, incoming Port 2 signals to Port 3, and incoming Port 3 signals to Port 4. This optical circulator provides high isolation, low insertion loss, high extinction ratio, and excellent environmental stability.
The PM RGB Combiner enables three primary colors in the visible wavelength region to be combined. The PM Combiner is based on environmentally stable thin film filter technology and is characterized with high extinction ratio, low insertion loss, and high return loss.
