Description

The Arista OSFP-400G-DR4 is a high-performance 400 Gigabit Ethernet transceiver designed for next-generation data center and enterprise network deployments. Supporting transmission distances up to 500 meters over OS2 single-mode fiber, this module utilizes four independent 100G optical lanes at 1310nm wavelength with MPO-12/APC connectors. Compliant with IEEE 802.3bs and OSFP MSA standards, it delivers low-latency, high-bandwidth connectivity for data center interconnects, cloud infrastructure, and high-performance computing environments.

FAQs

Q: What is the maximum transmission distance for the OSFP-400G-DR4?
A: The OSFP-400G-DR4 supports transmission distances up to 500 meters over OS2 single-mode fiber (SMF) with Forward Error Correction (FEC) enabled.

Q: Can this transceiver be used in breakout configurations?
A: Yes, the OSFP-400G-DR4 can be configured for 4 x 100G-DR breakout applications, allowing a single 400G OSFP port to connect to four separate 100G QSFP-DR transceivers using appropriate fiber infrastructure.

Q: Is the OSFP-400G-DR4 compatible with QSFP-DD form factor switches?
A: No, OSFP and QSFP-DD are mechanically incompatible form factors. However, on the optical side, OSFP-400G-DR4 and QDD-400G-DR4 modules can be interconnected as they follow the same 400GBASE-DR4 optical standards, enabling interoperability between OSFP and QSFP-DD equipped devices.

Q: What fiber type is required for this transceiver?
A: The OSFP-400G-DR4 requires OS2 single-mode fiber (SMF) with MPO-12/APC connectors. It uses four parallel fiber pairs (8 fibers total) to achieve 400Gbps throughput.

Q: What are the typical applications for this 400G transceiver?
A: Common applications include data center interconnects (DCI) within campus or metro areas, high-performance computing (HPC) clusters requiring ultra-low latency, cloud infrastructure backbone connections, and high-density enterprise network aggregation layers supporting 400G Ethernet and InfiniBand interconnects.
