Arista Compatible 400G OSFP DR4 Optical Transceiver

Designed for 400G Ethernet data centers, HPC and machine learning clusters, the Arista Compatible 400G OSFP DR4 Optical Transceiver provides 400Gbps throughput in a OSFP (IHS/Finned Top) form factor. It operates at 1310nm over SMF through a MPO-12/APC connector and supports link lengths up to 500m. The module meets CMIS 5.2, IEEE 802.3bs-400GAUI-8, OSFP MSA, IEEE 802.3 bs-400GBASE-DR4 and includes digital diagnostic monitoring for live status readout.

Product Highlights

• OSFP (IHS/Finned Top) form factor, 400Gbps data rate
• Wavelength: 1310nm
• Connector: MPO-12/APC

Built for 400G Ethernet data centers, HPC and machine learning clusters, this OSFP (IHS/Finned Top) module carries 400Gbps over SMF up to 500m per link. The MPO-12/APC interface and 1310nm optics match the standard cabling plant used in modern data halls, so existing trunks can be reused. It is interoperable with Arista Networks platforms and replaces the Arista Networks part OSFP-400G-DR4 directly. The link runs 8x50G-PAM4 modulation, which keeps it aligned with current 400G switch silicon.

Compliance: CMIS 5.2, IEEE 802.3bs-400GAUI-8, OSFP MSA, IEEE 802.3 bs-400GBASE-DR4. For projects standardized on Arista Networks hardware, this product replaces the OSFP-400G-DR4 directly, with identical fit and function. Every unit's EEPROM coding and link behavior are verified on real host equipment in our lab, so what arrives at your site is ready to use.

To order, quote OSFP-DR4-400G together with your quantity. Stock items ship quickly; for OEM orders we support custom labels, retail packing and vendor-specific coding, all handled in our own factory.

Standard packing is an anti-static bag plus blister protection, with cartons sized to keep products from moving in transit. We apply our standard labels by default; neutral packing or customer-branded labels, part number stickers and serial barcodes are all available on request.

Working directly with the manufacturer means no middleman limits. We support OEM and ODM projects, custom cable assemblies, alternative packaging and compatibility coding for major equipment vendors, with engineering support from the same team that designs our standard products.

Most orders travel by international express and arrive within days; palletized freight by air or sea is used for volume orders. If you prefer, we ship on your DHL, UPS or FedEx account, or deliver to your appointed agent in China for onward consolidation.

Every unit we ship is tested in our own test bed on mainstream switch and transport platforms before packing. Our test center has been fully upgraded, which sets us apart from other third party product providers: 10G, 40G, 100G, 200G and 400G transceivers and direct attach cables are verified on the latest top brand equipment, including selected original switches that can hardly be found elsewhere.
