Description

The Arista OSFP-800G-2VSR4 is an 800 Gigabit twin-port OSFP transceiver designed for high-density data center and AI cluster interconnects. Supporting 800GBASE-SR8 over multimode fiber, it delivers up to 50m reach on OM4 fiber using dual MPO-12 APC connectors. The module operates at 850nm and supports breakout configurations including 2x 400G, 4x 200G, and 8x 100G for flexible deployment in spine-leaf architectures and server connectivity.

Features

Twin-port OSFP design enables 64 ports of 400G in a 32-port OSFP switch chassis
- 8x 100G PAM4 parallel optics over dual 4-channel MPO-12 connectors
- Hot-swappable with finned top heat sink for air-cooled switch environments
- Supports 800G Ethernet and InfiniBand NDR applications
- Built-in Broadcom DSP and VCSEL technology for low latency and low BER
- Digital diagnostics monitoring (DDM) with CMIS 5.0 interface
- Backward compatible with 400G OSFP ports (platform dependent)
- Ideal for short-reach rack-to-rack interconnects in AI training clusters
- Low power consumption optimized for high-density deployments
- Class 1 laser safety rating

FAQs

Q: What fiber type and connectors does the OSFP-800G-2VSR4 require?
A: This transceiver requires OM3 or OM4/OM5 multimode fiber with dual MPO-12 APC connectors. The module has male (pinned) connectors and must be used with female (unpinned) fiber cables.

Q: Can this module break out to multiple lower-speed connections?
A: Yes, the OSFP-800G-2VSR4 supports multiple breakout configurations: 2x 400GBASE-SR4, 4x 200G, or 8x 100G, enabling flexible connectivity to 400G and lower-speed network equipment.

Q: Is this transceiver compatible with 400G VR4 infrastructure?
A: Yes, the module can connect to two 400G VR4 transceivers via two 12-core multimode fiber patch cords, allowing seamless migration from 400G to 800G networks using existing fiber infrastructure.

Q: What platforms support the OSFP-800G-2VSR4?
A: This transceiver is designed for Arista's high-density 800G switches such as the 7060X6 series, and is compatible with AI cluster, HPC, and data center spine-leaf architectures.

Q: What is the difference between OSFP and QSFP-DD form factors?
A: OSFP and QSFP-DD are different physical form factors and are not interchangeable. OSFP modules have a larger size to accommodate higher power consumption and thermal requirements for 800G speeds.
