AGILE OPTICAL COMPONENTS

Key Features

• Low polarization dependence

• Insensitive to vibration and electrostatic discharge (ESD)

• Extremely low wavelength dependence over C and/or L bands

• Mulitiple devices easily packaged into common housing

• Available in both normally open and normally closed states

• Available in three different packages

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 microelectromechanical systems variable optical attenuators (MATT) focus

on key network optical power management applications. JDSU offers MEMS

attenuators in normally open and normally closed states. The MATT series

attenuators fully comply with Telcordia 1221 reliability program. Key features

include a small size, low wavelength dependent loss (WDL), and high

reliability. JDSU provides three different package options: DIL MATT, TO

MATT, and Micro MATT.

The MEMS attenuator design achieves highly repeatable optical attenuation over

C and/or L bands through a thermally-actuated reflective vane that intercepts

light. Applied power/voltage actuates the vane and translates in and out of the

light beam. In a closed loop mode with constantly applied electrical

power/voltage, the MEMS attenuator achieves excellent performance over a wide

temperature range and in a variety of environmental conditions. DIL MATTs

include an internal temperature sensor which can be used to compensate the

temperature dependent performance for accurate open loop operation.
