Broadband Single-Mode Fiber Coupler
Shanghai Hanyu fiber couplers use established fused-biconical-taper (FBT) technology for low loss and low cost in single-mode and multimode devices. Because the fused coupling region is wavelength-sensitive, performance depends on wavelength and fiber type. Single-mode couplers are available at various wavelengths. Standard1x2/2x2 FBT couplers use Corning SMF-28 single-mode fiber and can be specified at1310nm,1480nm,1550nm,1625nm and other wavelengths within1280–1650nm. They provide accurate operating wavelengths and specified splitting ratios within a given bandwidth, with narrowband, broadband and ultrabroadband types. The basic2x2(1x2) unit can be cascaded into other configurations. The single-window broadband single-mode coupler meets its performance specifications within±40nm of the center wavelength and offers very low excess loss, typically below0.05dB, for long-term stability and reliability. The source describes its overall performance as world-leading.
