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.
