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,
Optimized electronic driver.
Operating conditions and general specifications
Design & integration
VOA - W1 - L1 - C1
Customization for wavelength from 500 nm to 1700 nm is available. For
specific requests and customization, please contact us.
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.
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 = Vπ) 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.
The high-speed VOA has a fast response time and the attenuation tuning speed is
typically less than 500 ns (min. attenuation ⇔ max. attenuation).
