Full-band and high-performance OSAs for testing optical systems and components
Targeted at providing advanced test solutions, the OSA-160, OSA-161, and OSA-201, JDSU’s field-ready full-band DWDM analyzer modules, use a new grating-based monochromator design (JDSU patents). These analyzers offer high optical selectivity and high measurement speed for accurate measurement of wavelength, power, and optical signal-to-noise ratio (OSNR) in the presence of multiple channels.
JDSU’s OSA-300, OSA-301, and OSA-303 are high-performance DWDM analyzer modules in the family of grating-based spectrum analyzers that are designed for ultra dense WDM applications (UDWDM) with high channel counts and tight channel spacing.
Advanced optical performance
JDSU’s OSA modules offer the full wavelength range of 1250 nm to 1650 nm for DWDM and CWDM (metro) applications, combining outstanding wavelength accuracy and high dynamic range. All instruments are equipped with an internal wavelength reference for on-line 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).
Rugged and fast mechanical design
JDSU’s OSA modules have a new opto-mechanical design based on a maintenance-free, fast galvanometer drive, providing the highest measurement speed and unsurpassed ruggedness for field and lab applications and for continuous operation and monitoring (JDSU patents).
Easy to use
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.
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.
Flexible measurement capability
In-depth analysis, featuring statistical evaluation, long-term monitoring, 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.
Built-in test applications
Test applications for optical amplifiers (EDFA) and laser sources (DFB) facilitate network component verification.
Ready for next-generation networks
With new signal analysis capabilities, all of JDSU’s OSAs are designed for high-precision measurements of power, wavelength, and OSNR in ultra high-speed networks with data rates up to 40G/43G and new modulation formats, such as RZ, CS-RZ, DPSK, and QPSK.
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 Gb/s. 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.
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.
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.
