Description

Farsince 25G SFP28 passive direct‑attach copper (DAC) is a hot‑pluggable twinax assembly for short‑reach 25GbE connections inside or between adjacent racks. The cable integrates two SFP28 ends and a low‑loss, shielded twinax link to deliver line‑rate 25 Gbps with extremely low latency and no optical modules or external power.  it is ideal for top‑of‑rack switch links to servers, storage, or DPU/NIC ports, as well as edge and 5G platforms where simple, robust patching is preferred.

The passive design minimizes power draw and heat load, while the compact SFP28 form factor and 21.25 mm minimum bend radius support dense routing in crowded panels. Each end is coded to SFP28 MSA for broad device interoperability and includes pull‑tab latches for quick service. Farsince offers multi‑vendor coding, custom labeling and acceptance test reporting, and can supply matched routing lengths to help maintain consistent channel budgets across your deployment.
