A micro lens was formed at the end of fiber to couple with active chips in LD and PD modules. Conical and wedge lensed fiber are both available, other shapes can be customized. And AFR can provide one stop service for fiber tail assembly, including lensed fiber, fiber metallization, AR-coating, feedthrough soldering, fiber connectorization, etc.
The PMIWDM series combines Filter WDM and isolator into a compact package to offer a cost saving solution. This device is ideal for fiber amplifier applications to combine signal and pump wavelengths with very stable 1550 nm signal isolation. It is designed and manufactured according to Telcordia standard.
The 1064 nm Polarization Maintaining Isolator is a micro optics device with low insertion loss, high isolation, high return loss, high extinction ratio and excellent environmental stability and reliability. This fiber isolator is ideal for amplifiers, fiber lasers and test instrument applications.
The 2 μm Filter Wavelength Division Multiplexer series is based on environmentally stable thin film filter technology. The devices combine or separate light at different wavelengths in a wide wavelength range. They offer very low insertion loss, low polarization dependence, high isolation and excellent environmental stability. High power handling capability can be achieved through unique pigtail processing and high quality AR coating.
