Fiber Tunable coupler with tunable coupling ratio Tunable Directional Coupler (SMF) Fiber tunable directional coupler (FTDC) has an all-fiber construction and provides the tuning range of 0-100% coupling ratio with negligible optical loss. It is based on evanescent field coupling using two side polishedfibers where the coupling ratio is tuned by adjusting the core-to-core geometric offset. Customer specified fibers and operating wavelengths are available including single-mode fibers, polarization maintaining fibers andother specialty fibers. Any design or specification can be changed without prior notice. |
