Because no real filtering is taking place, Michelson interferometer based optical spectrum analyzers cannot be put in a span of zero nm in order to watch the power at a given wavelength as a function of time.
Grating based optical spectrum analyzers contain either a single monochromator, shown in Figure 13, a double monochromator, shown in Figure 14, or a double-pass monochromator.
The T-BERD 8000 addresses fiber characterization through OTDR and optical spectrum analyzer
modules, CWDM/DWDM and transport layer test, and 10-Gb/s Ethernet test.
There is thus a strong need for a high-performance optical spectrum analyzer
that has none of these limitations.
While all Acterna OSA optical spectrum analyzers
offer high-performance optical measurements over the full wavelength range between 1250nm and 1650nm at high test speed, the OSA-300/301 modules deliver new advantages.
In addition, he said, JDSU has a full range of optical spectrum analyzers
ranging from compact to high performance.
With this capability the OWM can be used to predict failures in the DWDM network before valuable traffic is affected, as well as capturing problematic transient events on DWDM backbones invisible to most optical spectrum analyzers
Currently, optical test equipment, such as optical time domain reflectometers (OTDRs), optical light sources (OLSs), optical power meters (OPMs), and optical spectrum analyzers
(OSAs), are used in combination to qualify components and identify and measure failures in optical networks such as bad splices, bends, crimps, and other reflective and non-reflective events.
Digital Lightwave's OWM is a highly sophisticated DWDM analysis system that provides more functionality and reliability than traditional optical spectrum analyzers
at a significantly lower cost.
EXFO was deemed the market leader for a number of test solutions in the I&M segment including optical loss test sets, chromatic dispersion (CD) analyzers, polarization mode dispersion (PMD) analyzers, handheld optical spectrum analyzers
(OSA), handheld light sources and held strong market positions with its handheld power meters and optical time domain reflectometers (OTDRs).
Electro Rent already offers Anritsu's signal generators, power meters, spectrum analyzers, optical spectrum analyzers
, BER Testers, STM/SONET analyzers and Site Master(TM) cable and antenna analyzers.
Combined with a broad offering of high-end optical- and physical-layer test modules, including optical spectrum analyzers
(OSAs), polarization mode dispersion (PMD) analyzers, chromatic dispersion (CD) analyzers and OTDRs - all contained inside a single unit - EXFO's all-in-one solution allows customers to future-proof their test systems.
