Circadiant Announces 10 Gigabit Ethernet Stressed Recevier Conformance Test Option at NFOEC
Stressed Eye test is required by new 802.3ae standard.
Dallas TX - Circadiant Systems, Inc., the company making optical
testing simple, today announced its 10 Gigabit Ethernet Stressed
Receiver Conformance Test option for its award-winning Optical
Standards Tester (OST). The option enables 10 Gigabit Ethernet
systems and component manufacturers to measure compliance to the
new 802.3ae standard. Circadiant is demonstrating the OST at this
week's National Fiber Optic Engineers Conference, (NFOEC) booth
#1805.
"Our ability to test the new 802.3ae standard
lifts a burden off the 10 Gigabit Ethernet industry," said
John French, president and CEO, Circadiant Systems. "The Stressed
Eye option automates and simplifies testing to the standard and
accelerates the time-to-market for 10 Gigabit Ethernet components
and systems."
Option 10 for the A3306-A 10 Gb/s OST automates the
802.3ae Stressed Receiver Conformance Test for 10 Gb/s operation.
The option eliminates the need to "rack and stack" a
variety of separate instruments and puts all of the functionality
needed to generate a degraded eye into the OST. Receiver sensitivity,
with the degraded eye, is measured automatically and the instrument
calculates if the Device Under Test passes or fails. The instrument
consolidates many test instruments into one stand-alone or rack-mountable
unit and automates many optical communication tests such as receiver
overload or transmitter dispersion penalty. The OST also tests
10 Gigabit Ethernet LAN, 10 Gigabit Ethernet WAN, SONET/SDH, and
PoS and simultaneously tests layer 1-2-3.
The 802.3ae standard, ratified in May 2002, requires
receivers to operate with a BER of less than 1E-12 when tested
with a degraded input signal. The degradation includes added jitter
and interfering signal. Jitter is swept across a defined frequency
and amplitude range while the BER is monitored at the receiver.
The BER of a 10 Gigabit Ethernet LAN or 10 Gigabit Ethernet WAN
receiver must be compliant across all specified frequencies of
applied jitter and vertical eye closure
"10 Gigabit Ethernet is a new standard and many
companies will need to make these Stressed Eye Tests both in R&D
and in manufacturing to meet the new 802.3ae standard," said
Bill Pence, president, Ward/Davis Communications. "The Circadiant
OST is a quick and easy way for them to do it."
Circadiant has been singled out for their unique
layer 1-2-3 testing approach and savvy design by industry publications
including Lightwave and Test and Measurement World. Additionally,
many industry analysts have praised the value of Circadiant's solutions,
including Frost & Sullivan, whom awarded the company the Product
of the Year award in March.
Delivery of an OST with Option 10 is six to eight
weeks after receipt of order.
About OSTs
OSTs are an important new
class of test instrumentation. They have received
numerous awards as innovative test instruments
that reduce manufacturing test cycle times and
shorten a new product's time-to-market. Components
and instruments that measure layer 1, 2 and 3
that are commonly used to test optical communication
systems are consolidated into an OST. This enables
sophisticated algorithms and complex testing
procedures to be calibrated and automated by
Circadiant, instead of the user, and produces
a test instrument that is fast, accurate and
purpose-built for optical communication system
testing. 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.
Degradation includes control over jitter, OSNR,
interfering source, extinction ratio and optical
power as well as the ability to inject errors
into the layer 2 and 3 protocol signals.
