AGILE OPTICAL COMPONENTS
Electrostatic MEMS Variable Optical Attenuator
ESVOA Series
Key Features
• Low insertion loss
• Low wavelength dependent loss
• Low polarization dependent loss
• Multiple devices easily packaged into common housing
Applications
• Power equalization in multi-channel,
optically amplified networks
• Gain-tilt control in erbium doped
fiber amplifiers (EDFAs)
• Power control in narrowband
wavelength division multiplexers
(WDMs) and configurable networks
• Photoreceiver trimming
• Receiver protection/switch during
transmitter turn-ons
The JDSU Agile Optical Components family includes modulators, switches,
attenuators and tunable filters. These products provide the basis for spectrally
efficient DWDM transmission utilizing dispersion tolerant modulation, channel
monitoring, wavelength switching, remote power control and dynamic channel
selection. They support a wide range of flexible functionalities at lower
operational expenses for the Agile Optical Network. In addition, we have a
complete line of tunable lasers assemblies and sub-assemblies in our Agile
Transmission Module family.
JDSU Electrostatic MEMS Variable Optical Attenuators (ESVOA) focus on key
network optical power management applications. JDSU offers ESVOA series
attenuators in normally open and normally closed states. ESVOA series
attenuators fully comply with the Telcordia 1221 reliability program. Key features
include a small size, low wavelength dependent loss (WDL), and high reliability.
The ESVOA series attenuator achieves highly repeatable optical attenuation over
C and/or L bands using an electrostatic rotatable mirror. Applied voltage/power
actuates the mirror to rotate, changing the light coupling between the input fiber
and the output fiber of the ESVOA series attenuator.
