The MAX-840 Ethernet tester is a go-anywhere compact, upgradeable solution including 1G to 400G Ethernet testing capabilities based on the latest IEEE standards. It features a journey-to-400G design for ultimate flexibility; go with 400G now or start with up-to-100G testing and upgrade to 400G later. Covering the basics, it includes EtherBERT, TGEN, BERT, RFC2544, Fibre Channel (1X – 32X) and other core testing requirements. It supports a wide range of pluggable transceiver form factors, including SFP28, QSFP28, QSFP-DD, QSFP112, and OSFP.  The MAX-840 includes iOptics, an intelligent pluggable optics test application that can quickly validate any pluggable transceiver from 1G to 400G, as needed.
