COMMUNICATIONS COMPONENTS

Variable Slope Attenuators

VSA Series

Key Features

• Low insertion loss

• Wide attenuation slope range

• Available in low and high contrast variants

• Available in positive or negative slope variants

• Low tuning voltage

• Mountable on a PCB

Applications

The JDSU variable slope attenuator (VSA) equalizes uneven gain profiles inherent

to the use of optical amplifiers. The VSA is Telcordia GR 1209 and 1221 compliant

and uses hermetic sealing for increased resistance to environmental extremes. It is

available in low contrast and high contrast variants, and offers excellent positive

or negative slope optical performance in either the C or L bands.

• Remove cumulative error function

from amplifiers and filters

• Correct variations in amplifier gain

profile due to add-drop

multiplexing and Raman effect

The attenuation slope is precisely tuned using a stepper motor driven by an

external IC driver. The stepper motor adjusts the slope in small, uniform step

sizes, thus providing high resolution. The VSA is compact in size and can easily be

mounted on a printed circuit board (PCB). It requires minimum voltage. The

electrical pins extrude from the bottom of the package.

• Balance channel power in

reconfigurable networks

Compliance

The spectral diagram on next page shows the transmission spectrum after passing

through the VSA. Both positive and negative slope profiles are available.

• Telcordia GR 1209 and 1221
