Test & Qualification

Catch it on the bench, not in the field.

Diagnostic tools that simulate live traffic and validate ports across major form factors — from the team that builds the links too.

Port testing without a link partner. Emulates the electrical and thermal load of any pluggable module.

Passive and active loopbacks from 10G to 1.6T. Programmable power emulation of any optical or copper module, up to 60W.

Production test, system bring-up and field troubleshooting from SFP to OSFP1600, 10G to 1.6T.
