BFIH

Band Pass Filter/ Isolator Hybrid Combination BFIH Series Features Wide Operating Wavelength Range BAND PASS FILTER/ISOLATOR HYBRID COMBINATION Oplink’s BFIH is a compact combination of a bandpass filter and a polarization insensitive optical isolator. The built-in bandpass filter blocks the amplifiers spontaneous emission (ASE) in the erbium doped fiber amplifier (EDFA), thus significantly improving the amplifier’s performance.
