Direct-attach 25 GbE cable
This three-metre passive copper assembly carries 25 Gigabit Ethernet between two SFP28 ports without an external power source. It suits data-centre racks or campus switches where a short, low-latency link is required. The RoHS-6 compliant jacket is coloured black with an orange pull tab for quick identification.
Passive design removes power draw
Because the cable is passive it adds no heat load and needs no configuration on the switch side. The integrated SFP28 male connectors plug straight into compatible transceivers, reducing cabling bulk compared with active optical alternatives. Environmental certifications confirm restricted hazardous-substance content.
9.84 ft reach defines the use case
At 9.84 ft the assembly spans adjacent rack units or neighbouring top-of-rack switches but cannot cross longer rows. Buyers needing greater distance must choose active copper or fibre options instead.

Questions about this item
Will the passive copper construction need any firmware updates or active-component replacements over time?
The cable is entirely passive copper with no active electronics, so it requires no firmware updates and has no replaceable components during its service life.
What length-related signal limit appears first when running 25 Gbps links continuously?
At 9.84 ft the passive design stays within the SFP28 3 m reach specification, so insertion-loss margin is the first limit encountered under sustained 25 Gbps operation.
Does the cable generate measurable heat or draw extra power during all-day 25 Gbps traffic?
Being fully passive, the assembly draws zero power and produces no measurable heat beyond the negligible resistive loss of the copper conductors.
