QSFP-100G-XSR4 Arista Compatible Transceiver

Read as shorthand, the model name is the whole description: QSFP-100G-XSR4 — 100G signaling, QSFP28 form factor, XSR4 designation, Arista coding. TenFourOptics supplies it as the compatible equivalent of the Arista part of the same number: it carries host-matched EEPROM data, identifies correctly at insertion, and brings the port to 100G with no manual steps. DDM/DOM output stays available to the platform for day-to-day monitoring of the optic in service. Programming, identification, and diagnostic behavior are all confirmed before the unit is packed. OEM Equivalent: QSFP-100G-XSR4 Interface definitions follow the published MSA without deviation. TenFourOptics covers it under the GreenLights4Life® Limited Lifetime Replacement program. Physically stocked, so it ships same or next business day.
