1545nm High Power Singlemode PM Fiber Bandpass Filter
DESCRIPTION
Haphit provides fiber based passive components. The Bandpass Filter is made by thin film coating and micro-optics package technology with Polarization Maintaining (PM) fiber in and PM fiber out. It features flat-top spectrum, high Suppression Ratio and high Extinction Ratio. The Bandpass Filter will pass the signal light while block the unwanted/ASE light. The high power version can withstand high continuous wave (CW) optical power while maintaining high performance and stability. Y Type or X type is recommended to guide out high power ASE/unwanted light out. Customer can select only slow axis working (High ER Type) or both axis working option. Various pass bandwidth and fiber types are available, customized on bandwidth and consigned fiber type are also available on request.
