Anritsu releases 400GbE PAM4 BER Test

Anritsu announced the commercial release of its 64-Gbaud PAM4 Pulse Pattern Generator (PPG) and 32-Gbaud PAM4 Error Detector (ED) for use in 400GbE testing.

The new PAM4 BERT modules can be installed in the Anritsu Signal Quality Analyzer-R MP1900A series to implement a bit-error-rate test solution using either the 26.5625 Gbaud PAM4 x 8 lanes or 53.125- Gbaud PAM4 x 4 lanes methods. When using the PAM4 method to encode data as four amplitude levels, the gap between signal levels is one-third compared to the NRZ method, which reduces the unit time per symbol at higher baud rates, emphasizing the importance of signal quality in achieving high-speed transmissions.

Anritsu adds 53 Gbaud upgrade for PAM4 optical signal analysis

Anritsu has released new firmware downloads for the BERTWave MP2110A Sampling Oscilloscope that boosts its PAM4 analysis function from 26 Gbaud to 53 Gbaud for the production and inspection of optical modules.

Anritsu notes that current optical modules such as CFP8s use 26-Gbaud PAM4 optical signals, while future mass-produced QSFP-DD and OSFP modules will use 53-Gbaud PAM4 optical signals. Its solution can be used to support the development and production-line inspection of next-generation QSFP-DD optical transceivers expected to be deployed in data centers.

The BERTWave MP2110A is an all-in-one measuring instrument with built-in multi-channel Bit Error Rate Tester (BERT) and Sampling Oscilloscope, supporting bit error rate (BER) measurements, Eye Mask tests, Eye pattern analyses, high sampling speed of 250 kSample/s and low-noise (3.4 μW) high-sensitivity O/E interface. The BERT and Sampling Oscilloscope are required instruments for evaluating optical modules used by optical communications systems.

As well as NRZ technology, the MP2110A also supports PAM4 signal measurements including TDECQ, which enable all-in-one quality evaluations of optical modules at speeds from 25 to 400 G. In addition, the MP2110A, thanks to its high-speed measurement and PAM4 analysis, will play a key role in improving optical module production-line productivity. Moreover, adding 53 Gbaud support for quality evaluation of next-generation optical modules helps cut capital equipment renewal costs.

Teledyne LeCroy's Protocol Analyzer adds PAM4 50G-400G Ethernet

Teledyne LeCroy introduced a trace capture and analysis solution for the 802.3cd and 802.3bs 50/100/200/400GE four-level pulse amplitude modulation (PAM4) Ethernet specifications.

The new capability, which is available as a license for the company's SierraNet T328 protocol analyzer, enables higher data rates and enhanced reliability for future-generation data centers and cloud-based services.

Teledyne LeCroy notes that PAM4 signals are more susceptible to errors in noisy environments. To reduce the error rate, systems negotiate transmission parameters that maximize signal quality at the receiver. PAM4 Systems designers are demanding the link-layer analysis capabilities to ensure the negotiation among components is effective.

The SierraNet T328 can now help identify and reduce link-interoperability problems between major fabric components such as switches, routers, network interface adapters, servers, and Network Attached Storage (NAS).

"By providing real-time trace capture, decode, and analysis of the auto-negotiation and link-training functions, the SierraNet T328 has become the de facto standard for high-speed protocol analysis in development, debug, and test applications," stated David J. Rodgers, Ethernet and SAN Product Line Manager at Teledyne LeCroy.
