A 2*2 50/50 FBT coupler distributes an optical signal between two output paths at an approximately equal power ratio. Because it has two input ports and two output ports, it can support bidirectional coupling and signal distribution configurations.
Yes. The coupling ratio, fiber length, fiber coating, package dimensions, and connector configuration can be customized according to the system requirements. This version uses Corning HI1060 fiber, 250 μm bare fiber leads, a 3 * 50 mm steel-tube package, and no connectors.
