MTS/T-BERD 8000 Platform – Optical Spectrum Analyzers
Advanced optical performance
JDSU’s OSA family combines outstanding wavelength accuracy, high dynamic range and an ultra-
high resolution. All instruments are equipped with an internal wavelength reference for online
calibration without requiring disruption of in-progress measurements. The internal wavelength
calibrator is based on a physical constant reference that guarantees unsurpassed wavelength accu-
racy over the instrument’s lifetime without the need of external recalibration (JDSU patents), saving
recalibration cost.
One-step system qualification
One-button auto-testing guarantees that technicians need no special training to carry out a
DWDM test, making JDSU’s instruments suitable for both novice and expert technicians. An Auto-
Test mode automatically identifies WDM channels, selects the appropriate wavelength range, and
provides auto scaling and system qualification according to pre-defined parameters.
Flexible measurement capability
In-depth analysis, featuring statistical evaluation, and automatic storage capabilities, is provided.
This allows for DWDM system performance verification, including the variation of optical sys-
tem parameters (wavelength, power, and OSNR) as well as a series of measurements over a defined
period of time. Resulting reports are provided with average, minimum, maximum, and standard
deviation values of the measured parameters over time.
Powerful pass/fail link manager
Graphical and tabular display formats can be selected to assist in the installation, verification, and
troubleshooting of multi-channel DWDM systems. Built-in test functions deliver automatic pass/
fail evaluations based on pre-defined alarms, saving time and providing technicians with a quick
and intuitive overview of the complete set of results.
Measurement of signals at high data rates and new modulation formats
Data rates at 10 Gbps or higher have a larger optical bandwidth than the resolution bandwidth of
an OSA, and with new modulation formats like duobinary (DB), differential phase shift keying
(DPSK) or quadratur phase shift keying (QPSK), the spectral shape of a signal will change from one
peak to multiple peaks. Regular OSAs will no longer correctly measure the central wavelength and
the total signal power of such transmission signals.
JDSU OSAs are prepared for these scenarios as they have a new signal analysis for accurate mea-
surement of total channel power and center wavelength of modulated signals. All results will be
presented in the WDM table.
