Agilent's OmniBER offers 2.5 Gb/s Jitter measurements for OTU-1, OC-48/STM-16

NEW DELHI -- Agilent Technologies recently announced that the industry's most accurate 2.5 Gb/s jitter measuring instrument now has low intrinsic OTU-1 and OC-48/STM-16 jitter capability. The 2.5 Gb/s OmniBER communications performance analyser provides the most accurate and repeatable jitter with ITU-T O.172 jitter accuracy maps. It provides a receiver-only, fixed-jitter accuracy error of less than 20 mUI at 2.5 Gb/s. This small error gives much greater assurance of conformance to the 100 mUI industry standard, enabling a higher pass/fail threshold and improving throughput.

The accuracy maps provide the basis for a receiver-only performance calibration and specification, enhancing absolute accuracy and box-to-box consistency. Not only is the accuracy map a method for verifying the accuracy of jitter test equipment, but it is also used to set an optimal pass/fail threshold, thus improving device throughput. It enables a higher pass/fail limit to be applied when compared with the pass/fail threshold that should be used when using the O.172 specification.

In addition, the Agilent OmniBER has been enhanced with an expanded protocol decode coverage by providing a utility to support free-of-charge Ethereal protocol analysis software. This utility allows the encapsulated protocol to be fed into the Ethereal software for further analysis by removing the GFP-F structure; the Ethereal software enables link layer protocols to be captured and analyzed, which means that Ethernet encapsulated higher layer packet transport protocols such as MPLS, IPv6, L2TP, PWE3, etc., can be captured, analysed and debugged; and an USB memory stick support, which vastly simplifies the process of saving captured data on OmniBER and transferring the stored data to Ethereal software for the higher layer protocol analysis.
