FBT Coupler
FBT Coupler: Expert in efficient distribution of optical fiber networks
FBT coupler, also known as a fiber coupler, is an optical passive device that bundles one or more optical fibers together, melts, and stretches them on a tapering machine, and it can also show the changes in the splitting ratio in real time. When the splitting ratio reaches the design requirements, the melting and stretching ends, and one end retains one optical fiber as the input end, and the other end is used as a multi-channel output end. This splitter can couple the optical signal transmitted in the optical fiber in the coupling area of a special structure to redistribute the optical power.

Widely used
Suitable for telecommunication fiber optic networks, digital multimedia transmission systems, CATV systems, fiber optic sensors, fiber optic local area networks, etc.
The classification of FBT coupler can be divided from different perspectives, mainly including the following:
1. Classification by transmission medium
Single-mode optical splitter: Optimized for single-mode optical fiber, the operating wavelength is usually in the range of 1310nm and 1550nm, and is used in long-distance, high-bandwidth optical fiber communications.
Multimode optical splitter: Optimized for multimode optical fiber, usually operating in the range of 850nm and 1310nm, used for short-distance, low-bandwidth applications such as local area networks (LANs).
2. Classification by manufacturing process
FBT coupler splitter (Fused Biconic Taper Coupler): The splitting function is achieved by welding multiple optical fibers together from the side of the optical fiber. FBT splitters have low cost and customizable splitting ratios, suitable for general optical network applications.
PLC splitter (Planar Lightwave Circuit Coupler): uses planar lightwave circuit technology to achieve splitting function through optical waveguide. PLC splitter has high working wavelength flexibility and good stability, and is suitable for a wide range of wavelengths.
3. Classification by splitting ratio
According to the different splitting ratios, it is divided into several types of FBT splitters such as 1:2, 1:4, 1:8, 1:16, 1:32, 1:64, etc., and 2:N optical splitter or non-uniform splitting optical splitter can also be selected.
4. Classification by application scope
Optical splitters can also be classified according to single mode (1310nm) and multimode (850nm).
5. Classification by port form
Including X-type (2×2) coupler, Y-type (1×2) coupler, star type (N×N, N＞2) coupler, tree type (1×N, N＞2) coupler, etc.
These classifications reflect the diversity and flexibility of fused taper splitters in different application scenarios. Users can choose the appropriate splitter type according to specific network requirements.
