Circadiant to Demonstrate Automated 10 Gigabit Ethernet Stressed Receiver Conformance Test at SuperComm
IEEE 802.3ae 10 Gigabit Ethernet market growth increases
demand for test equipment.
Allentown PA - Circadiant Systems, Inc., the company making optical
testing simple, today invited SuperComm 2003 attendees to visit
the Circadiant exhibit booth (#21574) and observe the award winning
Optical Standards Tester (OST) measure a transceiver's compliance
to the 10 Gigabit Ethernet IEEE 802.3ae stressed receiver conformance
specification.
"We are seeing the demand for OSTs grow rapidly
as component and systems companies implement and expand their IEEE
802.3ae stressed receiver conformance testing," said Paul
Fitzgerald, Director, Sales & Marketing for Circadiant Systems. "New
generations of components and line cards are constantly being developed
to address the growing 10 Gigabit Ethernet market and they all
need to be tested for compliance."
A 10 Gigabit Ethernet compliant Xenpak transceiver,
provided courtesy of Intel Corporation, will be used as an example
device under test. "There is an increasing demand for our
optical transceivers that are compliant to the new 10 Gigabit Ethernet
stressed receiver conformance test and this reflects a growing
10 Gigabit Ethernet market," said Bob Zona, Senior Product
Marketing Manager, Intel Optical Products Group, responsible for
Intel's 10 Gigabit transceiver enterprise strategy.
The Circadiant Optical Standards Tester automatically
makes stressed receiver conformance tests. All degradations are
factory calibrated, Bit Error Rate vs. OMA is automatically plotted
on Circadiant's Straight-line BER chart, and a simple pass or fail
is indicated at the conclusion of the test.
The IEEE 802.3ae 10 Gigabit Ethernet standard was
adopted in June 2002 and includes the new stressed receiver conformance
test specification that all manufacturers of 10 Gigabit Ethernet
receivers and systems are required to meet. This new requirement
is intended to simulate worst-case conditions 10 Gigabit Ethernet
system will encounter so interoperability between 10 Gigabit Ethernet
systems is assured.
The stressed receiver conformance test defines a
degraded signal and the Bit Error Rate a 10 Gigabit Ethernet system
must maintain with specified Optical Modulation Amplitude. Signal
degradations include a poor extinction ratio, filtered rise and
fall times, a horizontal jitter mask, and applied vertical jitter.
The overall affect is to shrink the "eye" of the signal.
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.
