[2] all the parameters are excluding connectors [3] the mechanical tolerance should be +/-0.2mm on all package dimensions unless otherwise custom specifed. s0002 - r11. 20101028 band pass filter/isolator hybrid combination bfih series oplinks bfih is a compact combination of a bandpass flter and a polariza - tion insensitive optical isolator. the built-in bandpass flter blocks the amplifers spontaneous emission (ase) in the erbium doped fber amplifer (edfa), thus signifcantly improving the amplifers performance. ? wide operating wavelength range ? compact size ? high isolation ? u ltra low pdl & pmd ? highly stable & reliable ? epoxy-free optical path ? fiberoptic amplifers ? catv fiberoptic links ? wdm systems ? fiberoptic instruments ? transmitters and fiber laser sensors ? laboratory r&d
