Teledyne LeCroy announced availability of the SierraNet M1288 Protocol Test Solution, which supports analysis of up to 8 lanes of IEEE 802.3ck based Ethernet traffic and 112GbE four-level Pulse Amplitude Modulation (PAM4). The new M1288 tester enables troubleshooting from the physical layer through the application layer for up to 800 Gigabit Ethernet traffic.
The SierraNet M1288 Protocol Test Solution supports capture and analysis of links utilizing PAM4 or legacy Non-Return to Zero (NRZ) signal modulation techniques, at up to 8 lanes of Ethernet traffic, as well as clause 73 and 162 for auto negotiation and link training. The SierraNet M1288 offers error injection and analysis for all layers of the Ethernet Open Systems Interconnection (OSI) model, which helps design and test engineers shorten product time-to-market by:
- testing link negotiation to ensure it results in good signal quality
- confirming upper layer protocol compliance
- validating overall interoperability and performance
- stressing product designs to find issues early in the test cycle
“In network environments, as signaling rates increase so does the susceptibility to errors. To reduce the error rate, systems negotiate transmission parameters that should maximize signal quality at the receiver. PAM4 systems designers are demanding link-layer analysis capabilities to ensure the negotiation among components is effective” said Nick Kriczky, Vice President of Network Solutions at Teledyne LeCroy. “As the networking industry moves to 800Gb Ethernet, there is an growing need to fully validate Ethernet products. The SierraNet M1288 does this by identifying link-training issues and in validating protocol interoperability between major fabric components such as switches, network interface cards, servers, and Network Attached Storage (NAS).”
