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 Coarse WDM Module is expanding the bandwidth of Metro/Access Networks. The 4 channel and 8 channel CWDM modules are based on Coarse Wavelength Division Multiplexer devices. They can act as MUX/DEMUX with 20 nm channel spacing. It has low insertion loss, low PDL, high isolation and good thermal stability.
The High Power Polarization Insensitive Isolator is characterized with low insertion loss, high isolation, high power handling, high return loss, excellent environmental stability and reliability. The optical isolator is ideal for fiber laser and instrumentation applications.
The Polarization Insensitive Isolator Core is a Faraday Rotator based component for in-line fiber optic isolator. It can also integrate with other components to block back reflection or to enhance component isolation. It is insensitive to the input beams polarization state and has high isolation, low insertion loss, low PDL and low PMD.
The Singlemode Dual Window Wavelength Flattened Coupler offers very low insertion loss, low polarization dependent loss and excellent environmental stability. This coupler series offers accurate coupling ratios from 1/99 to 50/50 and is available with very good uniformity in a wide wavelength range of both 1310 nm and 1550 nm windows. These components find extensive applications to perform power splitting and mornitoring functions in all kinds of optical communication systems.
The Polarization Insensitive Tap Isolator combines a tap coupler and polarization insensitive isolator into a single compact package. It has low polarization dependent loss and very low insertion loss variation. This optical isolator is ideally suited for fiber amplifiers and fiberoptic systems where signal monitoring is required.
