Single-Mode FBT Fiber Optic Coupler-PON Network Fiber Coupler

FBT fiber optic coupler is an optical device based on fiber optic technology, which can couple optical signals from multiple fibers into one output fiber.FBT fiber optic coupler usually consists of one input fiber and multiple output fibers, and distributes optical signals from the input fiber to multiple output fibers through special fiber optic coupling devices to realize the distribution and multiplexing of optical signals.

FBT fiber coupler has the advantages of small size, light weight, low cost and easy to use, which is widely used in optical communication, optical sensing, optical waveguide, optical metrology and other fields. In the field of optical communication, FBT fiber coupler can be used in fiber grating, fiber spectrometer, fiber sensing and other devices.

There are two main methods of making FBT fiber couplers, one is hot-press welding method and the other is mechanical cutting method. The FBT fiber coupler made by hot-press welding method has higher coupling efficiency and lower insertion loss, but the production cost is higher; the FBT fiber coupler made by mechanical cutting method has lower cost, but the coupling efficiency and insertion loss are higher.
