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.

Mini Type Manual Variable Optical Attenuator (MVOA) operates by manually moving a shading element into optical beam. The shading element can be adjusted to get any attenuation value in a range. This MVOA features low insertion loss, good resolution, integrating high stability, good reliability and applies for pre-emphasis attenuation, transmitter power control, in-line power equalization and amplifier power control, etc.
