25G SFP28 passive copper cable
This Cisco SFP28 passive copper cable provides a direct 25 Gigabit Ethernet link between two SFP28 ports. It is built for data-centre and high-performance computing environments that need low-power, high-density connectivity without active optics. The 6.56 ft length suits rack-to-rack or intra-rack runs where a fixed copper assembly is preferred.
Fits SFP28 slots with no external power
Each end terminates in an SFP28 male connector that plugs directly into a compatible switch, router or NIC port. Because the assembly is passive it draws no additional power from the host system and requires no separate transceiver module. The fixed cable eliminates the need to stock or manage separate patch cords and optical transceivers for short-reach links.
Passive design maintains signal integrity over
The copper construction delivers consistent 25 Gb/s throughput across the entire 6.56 ft run without the latency or power overhead of active equalisation. Heat output remains negligible, helping preserve thermal headroom in dense chassis. The cable is intended for sustained 25G operation in controlled environments where bend radius and cable management follow standard installation practices.

Questions about this item
What is the maximum data rate this SFP28 passive copper cable supports?
The cable is built for 25 Gigabit Ethernet links using the SFP28 form factor.
Does the passive design generate any heat or require extra power during continuous operation?
No, the passive construction draws no power and produces no measurable heat while running all day.
Which ports must my equipment already have for this cable to plug in directly?
Both ends need an SFP28 male receptacle, so each device must provide a compatible SFP28 cage.
