Arista OSFP-800G-VSR8 | 800G OSFP Transceiver, VSR8, 850nm, 50m MMF, MPO-16

Q: What breakout configurations does the OSFP-800G-VSR8 support?
A: The OSFP-800G-VSR8 supports flexible breakout configurations including native 800GBASE-VSR8, as well as 2x 400GBASE-VR4, 4x 200GBASE-VR2, and 8x 100GBASE-VR1 breakouts, allowing scalable deployment from 100G to 800G speeds over the same infrastructure.

Q: What fiber cable types are compatible with this transceiver?
A: This module requires multimode fiber with MPO-16 APC (angled physical contact) connectors. It supports OM3 fiber up to 30m and OM4/OM5 fiber up to 50m. The module has a male (pinned) connector and requires cables with female (unpinned) MPO-16 connectors.

Q: Which Arista platforms support the OSFP-800G-VSR8?
A: The OSFP-800G-VSR8 is supported on Arista switches and routers running EOS version 4.35.0 or later. It is designed for high-density data center switches supporting OSFP form factor transceivers, particularly for AI cluster, HPC, and cloud infrastructure deployments.

Q: What is the difference between VSR8 and SR8 for 800G transceivers?
A: VSR8 (Very Short Reach 8-lane) uses an MPO-16 connector with 8 parallel fiber pairs, while SR8 implementations may use dual MPO-12 connectors. Both support 50m over OM4 fiber at 850nm wavelength with 8x 100G PAM4 signaling, offering similar performance for short-reach data center applications.

Q: Can this transceiver interoperate with other vendors' VSR8 modules?
A: Yes, the OSFP-800G-VSR8 is IEEE 802.3 compliant and can optically interoperate with any IEEE 800GBASE-VR8 compliant module regardless of form factor or vendor, provided both ends support the same optical interface standard and fiber infrastructure is properly matched.
