The Special Wavelength Coupler offers very low insertion loss, low polarization dependent loss and excellent environmental stability. Accurate coupling ratios from 0.01/99.99 to 50/50 are available with very good uniformity in the operating wavelength range. These components find extensive applications to perform power splitting and monitoring functions in all kinds of optical communication systems.

The Polarization Maintaining Fused Coupler offers very low insertion loss, high polarization extinction ratio and excellent environmental stability. Accurate coupling ratios from 0.01/99.99 to 50/50 are available with very good uniformity at center wavelength. These components find extensive applications to perform power splitting and mornitoring functions in all kinds of optical communication systems.
