Axiom Memory O14DR4T-AR-AX 400G DR4 OSFP Optical Transceiver

Connect 400G fabric links where an OSFP DR4 optical interface, reach up to 500 m, and Arista-compatible coding are required. Axiom Memory O14DR4T-AR-AX supports both Ethernet and InfiniBand NDR environments, making it suitable for high-bandwidth switch-to-switch, switch-to-server, and fabric interconnect paths that use 400G optical signaling. The OSFP form factor fits platforms built with OSFP optical cages, while the DR4 interface identifies the required 400G optical lane format. Its RHS flat-top configuration is a material selection detail for installations where module thermal geometry must match the target port environment. Select this configuration when the host platform calls for an Arista-compatible 400G DR4 OSFP optic rather than a different coding, reach, or thermal profile. Use the module for data center fabric links, aggregation paths, and high-throughput infrastructure that must carry either Ethernet traffic or InfiniBand NDR traffic. The specific combination of 500 m reach, OSFP packaging, DR4 signaling, flat-top RHS construction, and Arista compatibility distinguishes it within the 400G optic range. Confirm the host port's OSFP and DR4 requirements and ensure the installed optical plant supports the intended link distance before deployment.
