Gain Flattening Filter and Isolator Hybrid

Gain flattening filters (GFF) are used in amplifiers to equalize the amplified signal power of each channel in DWDM systems. The GFF and Isolator Hybrid for EDFAs is based on thin-film filter technology and metal bonding micro-optics packaging. It has an extremely low error function, low polarization sensitivity, and low insertion loss, as well as high isolation in a compact package. It features stable signal isolation and a flat profile, while operating over wide wavelength/temperature ranges and all polarization states. Shipping volume quantities.
