2x2 Low Insertion FBT Coupler

                                                             2x2 Low Loss Fiber FBT Coupler

The 2x2 coupler is a common passive optical component primarily used to split an input optical signal into two output ports in a specific ratio or to merge two optical signals into one, featuring bidirectional and symmetric properties. It is widely applied in fiber-optic communication, sensing systems, optical measurement, and laser systems.

The most common structure of this type of coupler is based on the fused biconical taper (FBT) technology, which involves heating and stretching two parallel fibers to form a coupling region, enabling mode coupling between the fiber cores and thus achieving energy exchange.

Specifications

Depending on the fiber type, 2x2 couplers can be categorized as:
Single-mode fiber coupler: Used in communication backbone networks, such as products in the 1310nm, 1550 nm 
Multimode Fiber Coupler: Suitable for industrial sensing, medical imaging, and other fields, such as models with core diameters of Ø200 μm or Ø600 μm.
Polarization-maintaining fiber coupler: Used in high-precision systems (such as fiber optic gyroscopes) to ensure stable polarization state.
