Tektronix adds critical support for 100G communications test

Tektronix, Inc. announced a significant expansion of its BERTScope Bit Error Rate Tester Series to meet growing 100G testing requirements.

With the introduction of the new Tektronix BSA286C BERTScope,Tektronix becomes the first test equipment manufacturer to offer complete support for standards-compliant testing up to 28.6 Gb/s, including error detection, pattern generation and clock recovery.

As service providers struggle to meet global bandwidth demands, development labs face time-to-market challenges such as extremely small timing and jitter margins as they work to bring compliant 100G components, routers and other products to market. The new BERTScope, with its industry leading sub 300 femtoseconds intrinsic jitter noise floor, brings extremely accurate BER test and root-cause PHY layer analysis to the growing portfolio of Optical Communications Test products from Tektronix.

For debugging applications, engineers can use the BSA286C to perform true jitter measurements on a variety of signals including low probability events, with the added ability to accurately decompose jitter into its random and deterministic components. As speeds increase, crosstalk has become a major source of jitter-related signal noise. The Tektronix BERTScope and Performance Oscilloscopes alike have adopted a jitter decomposition model that separates out bounded uncorrelated jitter (BUJ) for rapid insight into potential design problems related to crosstalk.

For 100G testing, 28.6 Gb/s bit error rate (BER) stressedreceiver testing has emerged as an important requirement for ensuring standard compliance and performance. This data rate provides adequate room for margin verification and forward error correction (FEC) that is required on top of the 25.78125 Gb/s data rate of 100GBASE-LR & ER-4.

The combination of high speed pattern generation and error detection on the BERTScope provides a fast time to answer for complex measurement scenarios that involve debug root cause analysis. For the full spectrum of 100 G design challenges, Tektronix provides instrument capability and measurement expertise for PHY TX, RX and Optical Modulation Analysis. Starting with the Tektronix DSA8300 Digital Sampling Oscilloscope for TX Eye Diagram Analysis along with the OM4000 Coherent Lightwave Signal Analyzer for Complex Modulation testing; the addition of the BSA286C BERTScope provides labs with comprehensive PHY test suite for 100G standards verification and debug.
