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.

40 channel DWDM system

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.

In-band noise measurement of optical channels passing
dierent routes in a ROADM network

MTS/T-BERD 8000 Platform – Optical Spectrum Analyzers

New in-band OSNR measurement technique

In ROADM networks the noise floor in between optical channels is suppressed by the optical fil­ters inside the ROADMs. In systems transmitting
ultra high data rates like 40G/100G at tight channel
spacing of 50 GHz, the modulation bandwidth is
larger than the channel bandwidth thus leading to
overlapping spectra. Both effects make conventional
OSNR measurement based on the IEC interpolation
method unreliable.

The OSA-500R is JDSUs second generation of opti­cal spectrum analyzers performing the in-band
OSNR A new optical polarization splitting (OPS) method (patent pending) is used to suppress the
transmission signal and to get access to the noise value inside the optical channel for measuring the
true in-band OSNR. The only viable solution for any test scenarios, whatever the ROADM filter
types, data rate or modulation formats.

Built-in test applications

Test applications for optical amplifiers (EDFA) and laser sources (DFB) facilitate network compo­nent verification.

EDFA test application

Drift analysis

Oine analysis OFS-100

Drift measurements

For optical performance monitoring it is essential to measure the key parameters over time. The
built-in drift test application provides the result of power, wavelength and OSNR over a customer
definable time frame in a graphical and numerical format. Drift measurements are important in
CWDM networks with uncooled laser, which have a typical wavelength of 0.1 nm/°C.

PMD test options

With the PMD option, the OSA can measure the differential group delay (DGD) for PMD charac­terization of optical fibers and systems. The measurement is based on the fixed analyzer method
(TIA/EIA FOTP-113) together with a broadband source and a variable polarizer.

Channel isolation (drop) and dual-port options

A unique channel isolation option is provided to extract a single DWDM channel from the entire
spectrum for further analysis with a SONET/SDH or Ethernet analyzer at data rates up to 12.5
Gbps. The built-in tracking function provides wavelength locking to the peak of the selected chan­nel in order to avoid channel frequency drift problems during long-term measurements. The
dual-port option (JDSU patents) provides simultaneous measurement of two optical signals, mea­suring the input and output of an optical amplifier at the same time, for example.

Advanced analysis solution

JDSU’s OFS-100 Optical FiberTrace Software is a PC-based software application within a true
Microsoft Windows environment, offering post-analysis capabilities and the generation of detailed,
professional OSA reports.
