Description
NVIDIA Mellanox MCP2M00-A00A 25GbE SFP28 Passive Copper Cable, 0.5m: This is a 0.5-meter passive direct-attach copper (DAC) cable for 25Gb/s Ethernet (25GbE) point-to-point links between SFP28 ports. The connectors are factory-terminated and the cable carries no optics or active electronics. This is a refurbished unit.
Engineering Context
The MCP2M00-A00A is the shortest length in this DAC family and is intended for back-to-back or stacked-switch links inside a single rack — ToR-to-ToR, MLAG peer links, or storage-controller cross-connects. Passive copper at 0.5m has the lowest possible insertion loss and sub-nanosecond cable delay. The integrated EEPROM identifies length, AWG class, and OEM to the host. Compliant with IEEE 802.3by 25GbE.
Deployment & Use Cases
MLAG / VPC peer links between two Top-of-Rack 25GbE switches. ToR-to-ToR stacking interconnects. Direct connection between adjacent storage controllers. ScaleIO/Ceph mesh links inside a chassis. Lab and bench testing of 25GbE NICs and switches at the lowest practical reach.

Compatibility & Hard Constraints
Compatible with NVIDIA Spectrum SN2010, SN2100, SN2410, and SN2700 switches at 25GbE, and with ConnectX-4 Lx, ConnectX-5, and ConnectX-6 Lx EN adapters. Requires SFP28 ports configured for 25GbE. Not a breakout cable; not compatible with QSFP28 ports directly. Length is fixed at 0.5m — too short to bridge between non-adjacent racks. Bend radius must be respected at this short length to avoid stress on the connectors.
Frequently Asked Questions (FAQ)
Q. What is the MCP2M00-A00A?
The MCP2M00-A00A is a 0.5m passive copper DAC with SFP28 connectors on both ends, rated for 25GbE Ethernet.
Q. Is this a splitter cable?
No. It is a straight 1-to-1 SFP28-to-SFP28 point-to-point assembly.
Q. Will T.E.S IT-SOLUTIONS confirm the configuration of MCP2M00-A00A before shipping?
Yes. T.E.S IT-SOLUTIONS (tes-itsolutions.com) inspects each unit and verifies vendor markings before dispatch from EU stock.
