This listing is for one brand-new Arista OSFP-400G-DR4 400 GbE transceiver (part number XVR-10211-40). This high-performance module supports 400GBASE-DR4 over parallel single-mode fiber using an OSFP form factor with an MPO-12 connector and digital diagnostics.

Key Features

• Supports 400 Gbps Ethernet via 400GBASE-DR4, compliant with IEEE 802.3bs.

• Delivers a reach of up to 500 meters over parallel SMF (OS2) using MPO-12 connectors.

• Utilizes 1310 nm wavelength via EML transmitters and PIN receivers, leveraging PAM4 modulation (4×106.25 Gb/s).

• Hot-pluggable OSFP form factor, compatible with OSFP MSA-compliant ports.

• Includes Digital Diagnostic Monitoring (DDM) for real-time monitoring of optical and environmental parameters.

• Power-efficient design (typically ≤9 W), featuring standard temperature operation (0 – 70 °C) for data center environments.

• Ideal for 400G backbone links, breakout applications, and high-density switch uplinks using existing fiber infrastructure.

Ideal For

• Enterprise and data center environments requiring high-throughput fiber links with minimal reach loss.

• Deployment with Arista OSFP-capable platforms and systems needing OEM-grade, hot-swappable 400G optics.

• Future-ready networking upsizes that require flexible, diagnostics-enabled modules for monitoring and maintenance.

• Breaking out 400G into multiple 100G links or integrating seamlessly into high-bandwidth architectures.
