Arista OSFP-400G-PLR4-Arista | 400G Transceiver, Single-Mode, 1310nm, 10km, MPO

Q: What is the primary use case for the OSFP-400G-PLR4-Arista transceiver?
A: This transceiver is designed for high-capacity data centre interconnects and campus backbone links requiring 400G throughput over distances up to 10 km. It is ideal for parallel single-mode fiber deployments and can be broken out into 4x 100G links for migration and flexibility.

Q: Can the OSFP-400G-PLR4-Arista be used with 100G optics?
A: Yes, the 400G-PLR4 supports breakout to 4x 100GBASE-LR and is interoperable with 100G-LR QSFP transceivers. This enables cost-effective migration paths and flexible network design in mixed-speed environments.

Q: What connector type does this transceiver use?
A: The OSFP-400G-PLR4-Arista uses an MPO-12 connector, which is standard for parallel optics applications. It supports up to 10 km transmission over single-mode fiber with parallel lanes.

Q: Is the OSFP-400G-PLR4-Arista compatible with QSFP-DD ports?
A: No, OSFP and QSFP-DD are different form factors and are not mechanically interchangeable. However, both form factors support the same 400GBASE-PLR4 standard, so OSFP-400G-PLR4 and QDD-400G-PLR4 transceivers can optically interoperate over the same fiber link.

Q: What platforms support the OSFP-400G-PLR4-Arista transceiver?
A: This transceiver is compatible with Arista switches that feature OSFP ports, typically found in high-density 400G data centre platforms. Refer to the Arista Transceiver and Cable Guide for specific platform compatibility and minimum EOS software version requirements.
