Nexans Data Communications Competence Center Analyzes OM3 and OM4 Reach Capabilities for 40G/100G Ethernet

Berk-Tek OM4 Pre-Terminated Fiber Assemblies Successfully Exceed 800m. Distance

New Holland, PA, April 15, 2011 - Nexans’ Data Communications Competence Center (DCCC), in New Holland PA, recently challenged the performance boundaries of Berk-Tek Pre-Terminated Optical Fiber Assemblies with rigorous experiments using a variety of test configurations and platforms. The results demonstrated that Berk-Tek’s GIGAlite-10 OM3, GIGAlite10-FB OM4, and GIGAlite10-XB OM4+ cables consistently exceed the IEEE Standard for both 40G and 100G Ethernet by a substantial margin.OM4 Pre-Term Assembly

“At the DCCC, we continually push performance boundaries” said Eric Lawrence, VP Emerging Technologies & Technical Director. “The fact that we perform Frame Error Rate testing, which is far more stringent than Bit Error Rate testing means that our tests run hundreds of times longer than the industry requires and our cables continue to exceed the industry standards. Using multiple connection points is also important because in real-world applications, our customers need to know that our cable can perform reliably and dependably in a variety of configurations.”

To provide solid, real-world performance results and to ensure interoperability, the DCCC utilized multiple test platforms and transceivers. The strong relationship with many component manufacturers has solidified the DCCC’s leadership position in the field and ensures maximum performance for customers in a wide variety of configurations.

The DCCC results are particularly noteworthy not only for the distances achieved, but also due to the utilization of Frame Error Rate testing instead of the more commonly used Bit Error Rate testing. In Frame Error Rate Testing, a single bit error will cause the entire frame to be discarded. This approach more accurately reveals the impact of errors on the application than BERT and is therefore a more meaningful metric. This testing arrangement means that the systems successfully exceeded the desired 10-12 Frame Error Rate for 40G over five hours rather than the 32 second minimum duration of Bit Error Rate testing.  Likewise, the 100G channels were tested successfully over two hours instead of the 13 second minimum BERT duration. In addition, the multi-connector channel configurations made the tests more challenging.
During the 40G Frame Error Rate testing using Avago 40G QSFP+ transceivers, the Berk-Tek standard OM3 fiber achieved 202 meters, which is double the reach specified by the IEEE 40GBASE-SR4 standard. Even more impressive were the results of the OM4 tests with a 10-connector channel where the Berk-Tek Pre-Terminated Optical Fiber Assemblies successfully transmitted beyond 800 meters, more than five times the reach specified by the standard. Separately, during the 100 Gb/s Frame Error Rate testing, Berk-Tek’s OM3 fiber met a 10-12 Frame Error Rate over 252 meters with three connections while the OM4 fiber reached 352 meters with 4 connections, more than double the reach of the IEEE 100GBASE-SR10 standard.
“Obviously, we are very pleased with the results,” stated Alfred Flores, Berk-Tek Pre-Terminated Optical Fiber Product Manager. “Successfully going 800 meters across 10 connection pairs using OM4 fiber clearly demonstrates what can be achieved when you combine our outstanding quality optical cable and connectors in support of next generation communications technologies.” 
 “These types of studies are part of the value that Berk-Tek brings to the customer beyond simply the components themselves.” said Mike Connaughton, Fiber Optics Products Business Manager for Berk-Tek, a Nexans Company. “The fact that the Competence Center successfully transmitted both 40G and 100G Ethernet to distances beyond those defined by the standard with our OM3 Pre-Term products was very positive. But more important than that, the stellar results of our OM4 grade fiber, when combined with the Avago transceivers, create a new benchmark in the industry and underscore the superiority of our OM4 cable assemblies for higher speed Ethernet applications.”
