Full-band, high-performance Optical Spectrum Analyzers for testing optical systems
and components

Targeted at providing advanced test solutions, the OSA-150, OSA-180 and the OSA-500 are the
next generation of JDSU’s DWDM analyzer modules.

A new monochromator design provides ultra high optical resolution, and outstanding wavelength
accuracy in a small and rugged OSA module, offering the best field solution for testing DWDM
and CWDM networks during installation, maintenance and trouble shooting.

The JDSU OSA modules differentiate by the optical measurement resolution and are graded into

three classes:

The OSA-150 is JDSU’s basic OSA with an optical resolution of 100 pm to measure CWDM and •
DWDM networks with moderate channel spacing of 100 GHz to CWDM.

The high resolution OSA-18x DWDM analyzers are suited for testing DWDM networks with •
tight channel spacing down to 50GHz. In addition the OSA-181 provides a unique channel drop
function to isolate single DWDM channels from the spectrum.

The ultra high resolution OSA-500 and OSA-500R have an industry leading resolution band-•
width of 35 pm for measurements in ultra DWDM networks with channel spacing down to
25 Hz.
The OSA-500R is equipped additionally with a new technique to measure the true OSNR in
ROADM systems and 40G systems.

MTS/T-BERD 8000 Platform – Optical Spectrum Analyzers

Advanced optical performance

JDSU’s OSA family combines outstanding wavelength accuracy, high dynamic range and an ultra­high 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 accu­racy 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 Auto­Test mode automatically identifies WDM channels, selects the appropriate wavelength range, and
provides auto scaling and system qualification according to pre-defined parameters.

Instrument setup

Graphical and tabular display showing pass/fail indicators
and out-of-range values

Precise and correct detection of new modulation formats

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 sys­tem 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 mea­surement of total channel power and center wavelength of modulated signals. All results will be
presented in the WDM table.
