Direct-attach 25 Gb/s SFP28 cable
The Mellanox MCP2M00-A003 is a passive copper SFP28 cable built for 25 Gb/s Ethernet links between network devices in a rack. It suits data-centre operators who need a fixed-length, low-power interconnect for top-of-rack or switch-to-server runs.
Thermals noise and power draw
As a passive assembly it draws no external power and adds no active cooling noise to the cabinet. The 28 AWG copper pair operates within the IEEE 802.3by and SFF-8402 limits at a 3.13 GB/s transfer rate without generating measurable heat.
Build quality and daily handling
Each end carries an SFP28 connector with an onboard EEPROM that the host reads for link validation. The black 9.84 ft jacket routes cleanly between adjacent ports, and the single-pair construction keeps the bend radius practical for dense patch-panel work. Buyers needing longer reaches or active equalisation will need a different cable type.

Questions about this item
How do I install the SFP28 connectors on the Mellanox MCP2M00-A003 cable, and what step is often missed?
Align each SFP28 connector with the switch or NIC port and push until the latch clicks. The step often missed is confirming the EEPROM data appears in the host system, which verifies the link is fully seated and recognised.
What maintenance or replacement will the 3 m, 28 AWG passive copper cable need over time?
No scheduled maintenance is required. Inspect the SFP28 latches and cable jacket periodically; replace the cable if the latch no longer holds, the jacket shows kinks or cuts, or link errors appear at 25 Gb/s.
What limit appears first when the cable runs at 25 Gb/s continuously?
The 3 m, 28 AWG passive construction reaches its signal-integrity limit before active or optical alternatives, so sustained 25 Gb/s traffic may show rising bit errors if the link exceeds the IEEE 802.3by passive-copper reach specification.
