Singlemode Dual Window Wavelength Flattened Coupler (SDC Series)
The Singlemode Dual Window Wavelength Flattened Couplers offer very low insertion loss, low polarization dependence and excellent enviromental stability. Accurate coupling ratio from 50/50 to 1/99 are available with very good uniformity in a wide wavelength range of both 1310 nm and 1550 nm windows. These components find extensive applications to perform power splitting and mornitoring fuctions in all kinds of optical communication systems.
