Arista OSFP-400G-XDR4-Arista | 400G OSFP Transceiver, Single-Mode, 2km, PAM4, MPO

Q: What is the difference between 400G-XDR4 and 400G-DR4?
A: 400G-XDR4 extends the reach of 400G-DR4 from 500 meters to 2 kilometers over single-mode fiber. Both use four 100G optical lanes at 1310 nm with PAM4 modulation and MPO-12 connectors, but XDR4 is optimized for longer intra-datacenter links between spine and leaf switches.

Q: Can this OSFP transceiver be broken out into multiple 100G connections?
A: Yes, the OSFP-400G-XDR4 can be broken out into 4 x 100GBASE-FR connections when used with an MPO-to-LC breakout cable, enabling connectivity between 400G switches and 100G QSFP28 switches or servers.

Q: Is this transceiver compatible with QSFP-DD ports?
A: No, OSFP and QSFP-DD are different form factors with distinct mechanical and electrical interfaces. This OSFP transceiver requires an OSFP-compatible port such as those found on Arista 7060PX4 Series switches.

Q: What switches support the OSFP-400G-XDR4 transceiver?
A: This transceiver is supported on Arista switches with OSFP ports, including the 7060PX4-32 and other 400G-capable OSFP platforms. Consult Arista's Transceiver and Cable Compatibility Guide for the full list of supported platforms and minimum EOS software versions.

Q: Does this transceiver require a software license?
A: No, Arista optical transceivers operate without additional software licensing. However, advanced switch features and EOS functionality may require appropriate software subscriptions on the host platform.
