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

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.

• 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

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.

• Receiver protection/switch during

transmitter turn-ons

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.

Compliance

• Telcordia 1209 and 1221
