The bandpass filter isolator hybrid is a compact combination of a bandpass filter and a polarization insensitive fiber isolator. The passband can be freely customized on user demand basis.   A gain flattening filter restores all wavelengths to nearly the same power. USIX’s gain flattening filters are manufactured based on customer specification and offer a highly reliable way to flatten the gain for both C-band and L-band fiber amplifiers.   This is single component solution for gain flattening and isolation. It enables both in-line compensation of gain flattening of EDFA and blocking of back scattered light power.   High performance fiber optic isolators are designed to achieve reliability requirements that meet Bellcore standards. They provide very low insertions loss in combination with very high isolation, polarization dependent loss and polarization mode dispersion over full temperature and wavelength ranges.   .
