Circadiant Introduces Electrical Stressed Eye Testing Capability

Controlled degradation aimed at emerging standards.

Allentown PA - Circadiant introduced electrical stressed eye testing capability packaged in the same instrument with optical stressed eye capabilities at SUPERCOMM 2004. The electrical test capability is aimed at emerging standards such the OIF Common Electrical I/O (CEI) project. Circadiant has the largest market share in the optical stressed receiver test market according to Frost & Sullivan.

The use of degraded eye test signals in standards is important to system vendors in order to guarantee equipment interoperability.  Circadiant’s new electrical features will test the XFP transceiver's XFI electrical interface and may be used to test 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.  

The electrical test capability will be available on the Circadiant Optical Standards Tester (OST) platform enabling a variety of automated tests.  The new electrical degradation capabilities are intended to begin addressing new standards and include include control over jitter, filter, interfering source, and SNR.

Pricing varies with the selection of available options.  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 and optical power 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, and SNR 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.
