NVIDIA/Mellanox MCP2M00-A003 Compatible 25G SFP28 Ethernet Passive Copper Twinax Cable, 3m (10ft)

Designed for hosts that recognize MCP2M00-A003, this SFP28 to SFP28 cable delivers 25G transmission over a fixed 3m (10ft) assembly. Its DAC construction provides a factory-terminated passive copper link without separate optical modules or patch cords.

OEM Part Number: MCP2M00-A003HT Part Number: MCP2M00-A003

Product Highlights

• Compatible alternative to NVIDIA/Mellanox MCP2M00-A003
• 25G connectivity at 25Gbps
• Interface configuration: SFP28 to SFP28
• Fixed length and part number: 3m (10ft), MCP2M00-A003
• Conductor specification: 30AWG
• Minimum bend radius: 21.25mm

This assembly uses 30AWG conductors, PVC (OFNR) jacket, minimum bend radius 21.25mm. These mechanical characteristics affect how the cable should be dressed behind the equipment. Avoid sharp edges, excessive ties and repeated tight bends close to the connector boots.

At 3m (10ft), this assembly can bridge non-aligned ports or adjacent racks while remaining a single direct-attach link. Support longer horizontal runs with suitable cable management and preserve space for cooling and future maintenance.

MCP2M00-A003 occupies the middle of this family between MCP2M00-A02A at 2.5m (8ft) and MCP2M00-A005AM at 5m (16ft). It adds 0.5m over the shorter option for extra routing clearance, while the next longer version adds another 2m. Measure the managed path and choose this version when its reach is sufficient without creating the slack associated with the longer assembly.

The intended application is 25G Ethernet, Data Center, 5G Wireless. Listed interface and protocol references include IEEE 802.3, SFP28 MSA, SFF-8402, Infiniband, EIA 364-1000. Confirm that the host firmware and port configuration support the same operating mode.

A passive DAC has no separate optical conversion stage. Its low-power, low-latency operation is useful for short equipment links, but the assembly must remain within the length and signaling mode accepted by both hosts.

The HT cable carries the compatibility configuration associated with MCP2M00-A003, while its mechanical assembly remains the fixed 3m (10ft) version described here. Incoming inspection, connector examination and a live link test are completed before packing. Customers with unusually old or new NVIDIA/Mellanox software can request a pre-order check.

This product is ordered as MCP2M00-A003 in 3m (10ft). Include the equipment model and software release if you would like a pre-order compatibility review. Other lengths use different part numbers and should not be substituted into the same order line.

Every MCP2M00-A003 compatible assembly undergoes link testing, compatibility verification and visual inspection. The 3m (10ft) cable is coiled without exceeding its minimum bend radius, fitted with connector protection and packed in an anti-static bag or protective tray before cartoning. Project labels and packing lists are available for volume orders.

Standard configurations normally ship within one to three working days. Worldwide courier, air freight and sea freight options are available, and shipments can also be sent on your own courier account or delivered to an appointed forwarder.
