Each QSFP-40G-ER4-A-ENC is individually programmed in-house and then Spirent® tested for performance and functionality as well as compatibility tested in target Arista Networks platforms. Old and new revisions of Arista Networks operating software are used for testing to ensure 100% compatibility. Our test lab contains Spirent® traffic emulation equipment, along with more than 80 of today's most popular switches, routers, and servers. All ENET Arista Networks compatible transceivers are MSA compliant for seamless integration and RoHS compliant for environmental conformity.
