Description
NVIDIA Mellanox MCP1600-E01A EDR 100Gb/s QSFP28 Passive Copper Cable, 1.5m: This is a 1.5-meter passive copper InfiniBand cable engineered for EDR fabrics at 100Gb/s. It is a fixed QSFP28-to-QSFP28 twinaxial assembly with no active electronics and no protocol conversion. This is not an Ethernet-targeted cable, not an AOC, and not a breakout cable. This is a refurbished unit.
Engineering Context
The MCP1600-E01A is built for short, in-rack EDR InfiniBand interconnects where reach is under 2m and where passive copper is preferred for power and cost. As a fully passive cable it draws 0W from the host port and contributes no port-level latency beyond the wire delay. It carries 4 lanes at 25Gb/s NRZ (4x EDR) for an aggregate 100Gb/s InfiniBand link. The 1.5m length suits HCA-to-leaf-switch runs in tightly populated racks where 2m would be slack. Twinaxial copper at this length offers good signal integrity for EDR.
Deployment & Use Cases
HCA-to-switch InfiniBand EDR connections inside a single rack — for example ConnectX-4/5 HCAs to SB7700 or SB7800 EDR switches. Compute-node uplinks in HPC clusters where short, low-power copper is preferred over AOCs. GPU compute pods running MPI traffic over EDR. Storage targets in EDR-attached parallel filesystems.

Compatibility & Hard Constraints
Compatible with NVIDIA Mellanox EDR switches (SB7700, SB7800) and ConnectX-4 / ConnectX-5 HCAs running InfiniBand EDR. Not validated for HDR or NDR fabrics, which use different speeds and connector profiles. Will train on QSFP28 100GbE Ethernet ports only when the device is configured for VPI Ethernet — otherwise it is an InfiniBand-only deployment cable. Does not support 4x25G breakout. Fixed 1.5m length, non-detachable.
Frequently Asked Questions (FAQ)
Q. What is the MCP1600-E01A?
The MCP1600-E01A is a 1.5m passive copper DAC with QSFP28 connectors, rated for InfiniBand EDR 100Gb/s.
Q. Is this a splitter cable?
No. It is a straight 1-to-1 QSFP28-to-QSFP28 point-to-point assembly.
Q. Will T.E.S IT-SOLUTIONS confirm the configuration of MCP1600-E01A before shipping?
Yes. T.E.S IT-SOLUTIONS (tes-itsolutions.com) bench-tests each unit where test topology is available, before dispatch from EU stock.
