Ascentest recently finished the test item of COM (Channel Operating Margin) for 100Gbps QSFP28 high-speed cables, on its fully auto-test system platform of HSCT (High Speed Cable Test system).

By far, Ascentest has completed the full test coverage, including MDNEXT, MDFEXT, ICN & COM, for 100Gbps QSFP28 high-speed cables, according to the standard of IEEE 802.3bj-2014, which entitles Ascentest HSCT to be the first fully automatic test system for 100Gbps QSFP28 cables in the whole industry, with the best Price / Performance Ratio.

HSCT system is based on the functionalities of Agilent/Keysight E5071C (Opt. TDR) and Ascentest MPS-HSCT Multi-Port Switch Matrix. The system automatically and accurately tests the Frequency & Time Domain parameters as well as Eye Diagram for high speed cables with data rate up to 100Gbps, and frequency up to 20GHz.

We are Ascentest, Creating Value through Persistent Innovation!

Notes:

MDNEXT: Mated Test Fixture Multiple Disturber Near-end Crosstalk

MDFEXT: Mated Test Fixture Multiple Disturber Far-end Crosstalk

ICN: Integrated Crosstalk Noise

COM: Channel Operating Margin
