1550nm Bandpass Filter

The Bandpass Filter is a micro optics device based on environmentally stable thin film filter technology. It is widely applied to blocking the unwanted noise signals in EDFA and fiber pump laser systerms, to get the signals needed. The components are characterized with high isolation, low insertion loss, high return loss, excellent environmental stability and reliability and high power handing capability.
