Circadiant Completes Stressed Eye Testing Capabilities with 850nm and 1310nm Wavelengths
Has more than 90% market share in the stressed receiver
conformance testing market.
Allentown PA - Circadiant Systems announced
at SUPERCOMM 2004 that Optical Standards Testers (OSTs) are now
available at 850 nm and 1310 nm in addition to the previously supported
1550 nm wavelength. This completes Circadiant’s ability
to make IEEE 802.3ae stressed receiver conformance tests at the
three 10 Gb/s wavelengths used in the standard. OSTs make optical
testing simple with factory calibrated degraded signals that automatically
test 10GBase-SR, 10GBase-LR and 10GBase-ER optical interfaces for
compliance to the stressed receiver conformance specification making
them ideal instruments for measuring XFP and other transceivers
as well as line cards from 10 GigE routers, 10 GigE switches, 10
GigE servers, SONET/SDH (OC-192 / STM-64), OTN (10.709 Gb/s) and
DWDM transmission systems.
"Circadiant is the undisputable market share leader in the
stressed receiver conformance testing market, generating more than
90 percent of the sales of complete instruments so far in 2004.
This leadership position is the direct result of Circadiant's OST
product feature innovation, including the optical methodology it
uses to degrade the optical eye, its compact size, its integrated
solution, and price", says Jessy Cavazos, Industry Analyst
and Sector Leader for the Communication Test Sector at Frost & Sullivan.
OST layer 1 degradations include added jitter, extinction ratio
level, OSNR level, interfering signal level, 4th order Bessel-Thompson
filter, optical power level, and PRBS errors. Errors and
alarms may be added in the layer 2 and 3 protocol signals (SONET/SDH,
PoS, 10 GigE WAN, 10 GigE LAN and OTN.) OSTs automate customary
R&D and manufacturing tests including BER vs. OSNR, optical
path penalty, optical overload and sensitivity.
The new OST 10E includes features that enhance testing: Secured-Accuracy(TM)
calibration confirms the OST’s accuracy and repeatability. Straight-Line
BER(TM) reveals unexpected DUT behavior immediately and conclusively to the
user. IntelliPass(TM) minimizes testing time. IntelliTime(TM) optimizes statistical
measurements. IntelliScript(TM) sequences tests and controls external instruments
such as oscilloscopes, environmental chambers and power supplies.
Pricing varies with the selection of available options. OST 10E
volume production begins in Q1 2005.
About Degraded Signal Testing:
Degraded signals are carefully specified to mimic real-world type worst-case
conditions instead of the traditionally used near-perfect signals. The IEEE
802.3ae specification included a degraded signal test, called the stressed
receiver conformance test, to provide 10 Gb/s Ethernet users with the same
Ethernet experience they were accustomed to - just plug the equipment in
and it works. This testing philosophy carried over to other standards, i.e.
10 Gb/s FibreChannel, and is growing in popularity as a way to test components
and line cards to assure interoperability. Optical degradation includes control
over jitter, OSNR, interfering source, filter, extinction ratio, optical
power and PRBS errors as well as the ability to inject errors into the layer
2 and 3 protocol signals. Electrical degradation includes control over
jitter, filter, interfering source, SNR and PRBS errors, as well as the ability
to inject errors into the layer 2 and 3 protocol signals. .
About OSTs:
OSTs are pre-packaged test instruments which cover most of the tests required
by line card and transceiver/transponder manufacturers. OSTs make optical
testing simple by including sophisticated algorithms and complex testing
procedures all calibrated and automated by Circadiant. OSTs are used
in R&D or in global manufacturing applications to shorten a new product's
time-to-market and reduce manufacturing cycle times. The components
and instruments that measure layer 1, 2 and 3 that are commonly used to test
optical communication systems are consolidated into an OST. Individual and
group test results are displayed on appropriate scales with statistical confidence
levels clearly shown to help users understand the behavior of a Device Under
Test. An OST also allows the user to degrade test signals to simulate
worst-case operating conditions.
