Band Pass Filter/Isolator Hybrid
Combination
BFIH Series
Product Description
Oplink’s BFIH is a compact combination of a bandpass filter and a polariza-
tion 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.
