Variable optical attenuators

The high-speed Eclipse variable optical attenuators are solid-state and fit in a 1.03 x 0.4-in. package. Optical-signal strength can be adjusted over the complete 20-dB range in less than 500 µs. Depending on the application, the device can be set to maintain an electronically adjustable value of either attenuation or output power.
