FBT fused splitter is an optical device that combines or splits power from optical fibers. Optical splitter divides light from a single fiber into two or more fiber channels.
Features
l Low loss
l Low polarization dependence
l With all bands
l Still being stable under high temperatures
l With mini package dimensions
Applications
l Optic communication system
l Fiber optic sensor
l Photo switch
l EDFA
