Product overview
Arista lists CAB-S-S-25G-5M as a SFP28 to SFP28 passive direct attach copper twinax cable (25G, 5m). Reach, fibre type and connector have to agree along the whole path, and a patch panel in the middle counts. This assembly is 5m. Send the run length and the fibre already installed and we will match it.
Quotes are itemised down to the accessories, so nothing that is needed to make the part work is left off and discovered later.

Questions buyers ask about this part
- Is CAB-S-S-25G-5M genuine and is the warranty intact?
- Yes — new and sealed, with the Arista warranty and the firmware update path intact. We do not sell refurbished stock as new, and we do not source grey-market units.
- Will CAB-S-S-25G-5M work in my server?
- Tell us the switch at both ends of the link. Optics are frequently vendor-coded, so a module that is electrically correct can still refuse to come up; we confirm the coding for both ends before it ships.
- Do you accept purchase orders and quote at volume?
- Yes. Purchase orders are accepted from qualified organisations, net terms are available on approval, and tiered pricing applies at quantity. Tell us how many you need.

Specifying a system, not just the part?
Optics and cabling are part of the fabric spec on a cluster build — both ends and the switch have to agree.
