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.
