The FBT Coupler Splitter uses melt taper technology to control the melting and stretching process of optical fibers, forming a special waveguide structure and achieving uniform distribution of optical signals. This technology ensures the stability and consistency of optical signals during the distribution process. Provide multiple coupling ratio options, such as 1×2, 1×4, etc., which can be flexibly configured according to actual application needs. At the same time, its spectral ratio can be monitored in real-time according to needs, and unequal splitters can be made to meet the optical power allocation requirements in specific scenarios, with good thermal stability and power bearing capacity, meeting the needs of various application scenarios.
