Applications

Note:

[1] The maximum IL is under all states of polarization and within the full operating temperature and wave-

length ranges specified.

[2] All the parameters are excluding connectors

[3] The mechanical tolerance should be +/-0.2mm on all package dimensions unless otherwise custom specified.

Band Pass Filter/Isolator Hybrid

Combination

BFIH Series

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.
