Variable Optical Attenuator
PN L-6001-VOAxx-1
DESCRIPTION
The VOAxx-1 is a Variable Optical Attenuator module that plugs in to theXBERT and ParalleX™ Chassis. Versions for single mode (VOASx-1) andmultimode (VOAMx-1) use are available, covering wavelength ranges of1270-1350nm/1510-1590nm (SM), and 800-1000nm (MM). The module
also incorporates a coupler with monitor output, allowing for simultaneous
measurement of optical power. When used in the XBERT chassis withEBERT, Clock, XFP and power meter modules, users can performreceiver sensitivity tests with one instrument.

XBERT PLATFORM: LETS YOU START SMALL AND GROW BIGXBERT is a low-cost, modular Bit Error Rate Test
Platform used for verification and test of 10Gb/s andabove optical and electrical chip, sub assembly andsystem designs. ParalleX™ allows users to performseveral BER tests at once using a single clock source.
The system is ideal for developers desiring to run
simultaneous BER tests on parallel interfaces or multiple
independent interfaces. XBERT and ParalleX™ arescalable so users can start off with a single channel andadd modules to grow the system. Manufacturers canrealize great savings by taking advantage of the XBERTand ParalleX™ system’s scalability to perform parallel
testing in volume production environments.

Sensitivity measurement
When used in the XBERT chassis with EBERT, Clock,
XFP/SFP+ and power meter modules, users canperform receiver sensitivity tests with one instrument.
The optional LabViewTM based Control Software
provides automatic sensitivity measurements of ROSA
(Receiver Optical Sub-Assembly) and receive sectionsof transceivers (XFP, SFP+ etc). The software isintended for automated test in mass production andoffers pattern dependant and frequency dependant
BER curves versus optical input power.
