FAQs

Q: What is the difference between OSFP-400G-XDR4 and OSFP-400G-XDR4-S?
A: The OSFP-400G-XDR4-S uses SN optical connectors instead of the standard MPO-12 APC connectors found on the OSFP-400G-XDR4. Both provide the same 400G XDR4 performance over 2km single-mode fiber, but the connector type differs for specific deployment requirements.

Q: Can this transceiver be used for 100G breakout applications?
A: Yes, the OSFP-400G-XDR4-S supports 4x 100GBASE-FR breakout, allowing a single 400G port to connect to four 100G endpoints. This is ideal for connecting 400G spine switches to 100G leaf switches or servers using appropriate breakout cables.

Q: What platforms support the OSFP-400G-XDR4-S transceiver?
A: This transceiver is designed for Arista 400G OSFP-capable platforms including the 7060PX4 series and other data center switches with OSFP ports. It requires EOS software version 4.24.0 or later for full compatibility.

Q: Is this transceiver compatible with other vendors' 400G XDR4 modules?
A: Yes, the OSFP-400G-XDR4-S follows industry-standard specifications and offers optical interoperability with other 400GBASE-XDR4 and 400GBASE-DR4 modules over appropriate distances, enabling multi-vendor deployments.

Q: What type of fiber cabling is required for this transceiver?
A: The OSFP-400G-XDR4-S requires parallel single-mode fiber with SN connectors. It uses four fiber pairs (8 fibers total) to transmit 100 Gbps per channel over distances up to 2km, making it suitable for intra-data center and campus interconnects.
