Produts Details
Product Name: Singlemode Broadband Coupler (SBC Series)
The Singlemode Broadband Coupler offers 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. These components find extensive applications to perform power splitting and mornitoring functions in all kinds of optical communication systems.
