What is FBT coupler?
FBT splitter, or FBT coupler, is an optical splitter that uses the Fused Biconic Taper (FBT) technique. FBT couplers are fused in tree structures to combine optical splitting effects to create power ratio output of 1×N or 2×N, where “N” is the number of desired outputs.
Fiber optic coupler is one type of fiber optic component that allows for the redistribution of optical signals. It covers a wide range of fiber optic devices such as optical splitters, optical combiners, and optical couplers. A fiber optic coupler is a device that can distribute the optical signal from one fiber among two or more fibers, or combine the optical signal from two or more fibers into a single fiber.
Usually, optical signals are attenuated more in an optical coupler than in a connector or a splice because the input signal is not directly transmitted from one fiber to another, but divided among the output ports. For instance, with a 1 x 2 fiber optic coupler, each output is less than one-half of the power of the input signal (over a 3dB loss).
What is the use of optical coupler?
Optical coupler is a semiconductor device, which is designed to transfer electrical signals by using light waves in order to provide coupling with electrical isolation between circuits or systems.
Applications of Fiber Optic Couplers
In local area network (LAN) applications, fiber optic couplers are used in either bus architecture or star architecture. In a star network topology, the stations branch off from a central hub, much like the spokes on a wheel. Each network device connected by the star coupler can communicate with each other.
