Fibre Optic Band Pass Filter
The Band pass Filter is a micro optics device based on environmentally stable Thin Film Filters technology. It is used to block out unwanted noise signals in EDFAs and DWDM systems. The components are characterized with high isolation, low insertion loss, high return loss, excellent environmental stability and high power handling capability.
