NVIDIA Mellanox MCP1600-E01A 100Gb/s EDR QSFP28 Passive Copper DAC, 1.5m, 30AWG — Lot of 5: This listing is for a lot of five (5) units of MCP1600-E01A passive copper direct attach cables, each 1.5 meters long, for InfiniBand EDR 100Gb/s point-to-point interconnects. Each cable uses QSFP28 to QSFP28 connectors with 4 lanes of 25Gb/s NRZ signaling. These are passive copper assemblies with no active electronics — not active copper cables (ACC) and not active optical cables (AOC). Refurbished units.
Engineering Context
The MCP1600-E01A is a 1.5m EDR-rated DAC engineered for short, in-rack InfiniBand fabric connections. Passive copper at EDR 25Gb/s per lane offers the lowest power draw (0W) and lowest latency option for short links. The 30 AWG conductor gauge balances signal integrity against cable bulk and bend radius. The buyer receives five (5) cables in a single lot — useful when wiring multiple compute or storage nodes to a TOR switch in one purchase. The LSZH jacket meets common data center fire safety requirements.
Deployment & Use Cases
Bulk wiring of HPC compute clusters where multiple nodes need identical 1.5m EDR connections to a Top-of-Rack switch. Storage fabric expansion in InfiniBand-attached arrays. Spare-stock buffering for production EDR fabrics. AI training racks where dense, low-latency, low-power node-to-switch connectivity is required.
Technical Specifications
OEM: NVIDIA Mellanox
Part Number: MCP1600-E01A
Lot Quantity: 5 cables per lot
Form Factor: QSFP28 to QSFP28 (Point-to-Point)
Data Rate: InfiniBand EDR 100Gb/s (4x 25Gb/s NRZ)
Cable Type: Passive Copper DAC
Length: 1.5m per cable
Conductor Gauge: 30 AWG
Jacket: LSZH (Low Smoke Zero Halogen)
Protocol: InfiniBand EDR
Power Draw: 0W (passive)
Condition: Refurbished — Tested by T.E.S IT-SOLUTIONS
Compatibility & Hard Constraints
Compatible with NVIDIA Mellanox Switch-IB 2 EDR switches (SB7700, SB7800 family) and ConnectX-4, ConnectX-5 EDR-capable adapters. Both ends require QSFP28 ports running InfiniBand EDR. Not compatible with HDR 200Gb/s ports unless the host explicitly negotiates down to EDR — link rate will not exceed 100Gb/s. Passive copper reach at EDR is limited; this cable is fixed at 1.5m. Lot quantity is fixed at 5 units; not sold individually under this listing.
