Bandpass Filter/Isolator Hybrid BFIH Series Features * Wide Operating Wavelength Range * Compact Size * High Isolation * Ultra Low PDL & PMD * Highly Stable & Reliable * Epoxy-Free Optical Path OPLINK's BFIH is a compact combination of a bandpass filter and a olarization insersitive fiber isolator. The built-in bandpass filter blocks the amplifierd spontaneous emission (ASE) in the erbium doped fiber amplifier (EDFA), thus significantly improve the amplifier's performance.
