A like-for-like exchange is the point of the SFP-10G-DW-63.86: 10G operation in the SFP form factor, mirroring the Arista part of the same number so the replacement inherits the original's role without design changes. Arista hosts accept its coding on first seat and no reconfiguration follows.

It is the -63.86 member of the DW series; adjacent variants differ only by suffix, so orders should carry the full part number. DDM/DOM output is retained, meaning the monitoring picture stays unchanged after the swap. MSA compliance keeps its electrical and management planes standard alongside other conforming optics. Backed by the GreenLights4Life® Limited Lifetime Replacement Warranty. In-stock items ship same or next business day — contact 10.4@tenfouroptics.com to confirm availability and lead time.
