Broadband Single-Mode Fiber Coupler
The fiber couplers produced by Shanghai Hanyu using mature fused biconical taper (FBT) technology feature low loss, low cost and mature processes, and are suitable for making single-mode, multimode and other optical couplers. However, because the coupling region produced by the fused biconical taper (FBT) technology is wavelength-sensitive, it is subject to constraints such as wavelength and fiber type. Currently, our company can provide single-mode fiber couplers of various wavelengths. The 1x2/2x2 standard fused biconical taper fiber couplers are made of Corning SMF-28 single-mode fiber. The operating wavelength can be set to 1310nm, 1480nm, 1550nm, 1625nm, etc. Other operating wavelengths in the 1280nm-1650nm range can be specified. The fiber couplers produced by fused biconical taper technology offer accurate wavelength and provide a settable splitting ratio within a certain bandwidth, and by bandwidth can be divided into narrowband, wideband and ultra-wideband types. The most basic unit is the 2x2 (1x2) type, but various structures of optical couplers can be made by cascading. Shanghai Hanyu's single-window wideband single-mode fiber couplers can ensure that all performance specifications are fully met within an operating bandwidth of +/-40nm around the center wavelength, while having very low excess loss (typical value less than 0.05dB). Therefore, the devices have excellent long-term stability and reliability, and the comprehensive specifications of the products represent the world-leading level.

Multi-axis fibre-optic couplings regulate the design through high precision five-axis; maintain the interface and fibre-optics in motion; align the positions of the inner lenses X and Y, respectively; and align the Z-axis orientations with the angles of the Z-axis based on the three Z-axis regulators; and meet the user ' s laser alignment/associate straightness functional needs. The overall structure is compact; it is easy; it is heat-stabilized; it is high resolution-to-structure; it is suitable for long-term or short-term alignment/precision. In addition; the position of the K key at the fibre-optic interface can be reconciled with three fixed screws of screwdrivers; and the alignment of the fibre-optics for protection purposes. The locks on the Z-axis adjuster can be locked by locking the wrench; fixed lenses can be leaned over and tilted at an angle. The panel position contains a tight screw with an X/Y axis regulator; the X/Y axis regulator can be fined up by the adjustment tension. X/Y axle adjuster with a lock screw on the side X/Y axle; normally without locking; if in a larger vibration and impact environment; if a lock screw lock is required Tight

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.
