Single-mode coupler module box Fiber Optic Couplers Adfiber
Single-mode dual-wideband tree/star coupler / 1x4 - Operating wavelength: 1310/1550±40 (*1310/1550±20) or Customized Single-mode dual-wideband tree/star coupler / 1x4 - Maximum insertion loss: 7.3 (*7.2) Single-mode dual-wideband tree/star coupler / 1x4 - Uniformity: 1.6 (*1.4)
Fused biconical tapering brings two or more stripped fibers together in a defined arrangement, fuses them under high heat and simultaneously stretches them from both sides to form a special double-taper waveguide in the heated region for optical power coupling. A splitter/coupler distributes one optical input to multiple or two outputs, or combines multiple or two inputs into one output. Port configurations include X, Y, star and tree couplers.

Electro-optic deflectors (EODs) are optical devices used to steer or deflect light beams by applying an electric field to a specialized optical crystal. Unlike mechanical beam steering systems that rely on moving mirrors, electro-optic deflectors enable high-speed, non-mechanical beam control with exceptional precision and responsiveness. They are widely used in laser scanning, optical communications, microscopy, laser printing, spectroscopy, and scientific research, where rapid and accurate laser beam positioning is essential.
For low-frequency RF, electromagnetic testing and power combining systems, conventional resistive power dividers bring high insertion loss, while standard directional couplers cannot provide equal-amplitude signals with 180° phase shift. They fail differential circuits, balanced amplifiers and signal cancellation systems.
