Manufacturer direct 1550nm high power polarizing fiber circulator package steel tube circulator Fiber jumper circulator
Optical Fiber Circulator
Port ring line is a kind of compact high-performance optical components and the input signal can be transmitted from port 1 to port 2, at the same time another input signal transmitted from port 2 to port 3 this device has high isolation and low insertion loss High extinction ratio and good environmental stability It is a special kind of fiber optic components, with single fiber bi-directional transmission function This feature is typically combined with FBG and other reflective components used in DWDM systems to use bidirectional communication systems for dispersion compensation for EDFA applications and OTDR measurements
