Applications

Lasers Sensors

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.
