Insertion loss Polarization dependance Transient response characteristics - Ordering information High-speed optical devices & components > Sub-microsecond high-speed variable optical attenuator The voltage controlled high-speed VOA (variable optical attenuator) is based on

electro-optic elements offering high-speed performances as well as compact

dimensions for easy integration or limited space environments.

The main characteristics are:

• Sub-microsecond attenuation tuning speed (full range),

• Low power consumption,

• Compact dimensions,

• Optimized electronic driver.

Design & integration

VOA - W1 - L1 - C1 Example:

Customization for wavelength from 500 nm to 1700 nm is available. For

specific requests and customization, please contact us.

(standard VOA) * Due to the design and assembly of the components, the VOA module has a

considerable flexibility when positioned on a circuit board. The dedicated driver board

with the VOA mounted is compact and can be integrated easily.

Typical characteristics Insertion loss The unique and patented configuration of the electro-optic element in the high-speed

VOA can make the driving voltage as low as around 25 V.

The insertion loss at the minimum attenuation (V = V_π) is lower than 1.5 dB for a

large temperature range and the wavelength loss dependence is typically smaller

than 0.5 dB.

Polarization dependance loss (PDL) The PDL is very small when V = Vπ for a large range of temperature within the

specified wavelength operation band as it can be seen on the following experimental

measurements. The PDL is smaller than 0.5 dB even for larger attenuations.

Transient response The high-speed VOA has a fast response time and the attenuation tuning speed is

typically less than 500 ns (min. attenuation ⇔ max. attenuation).
