Description

NVIDIA Mellanox MC2207130-0A1 56Gb/s QSFP+ Passive Copper DAC, 1.5m: This is a 1.5-meter passive direct attach copper (DAC) cable with QSFP+ connectors on both ends, rated for 56Gb/s FDR InfiniBand and 56GbE. The assembly is passive Twinax with no active components. This is a new unit.

Engineering Context

The MC2207130-0A1 covers the typical adjacent-rack and same-rack reach where copper still beats fiber on cost and latency. Passive copper introduces no SerDes processing, providing the lowest port-to-port latency available in the QSFP+ family. Cable diameter and bend radius are larger than fiber, so cable management in dense ToR deployments needs planning at 1.5m.

Deployment & Use Cases

FDR InfiniBand ToR-to-server links in HPC compute racks. 56GbE Mellanox-proprietary Ethernet aggregation in the same row. Inter-switch stacking links across two adjacent racks. Backwards-compatible 40Gb/s deployments where 1.5m suffices for the run.

Technical Specifications

Compatibility & Hard Constraints

Compatible with NVIDIA Mellanox SwitchX/SwitchX-2, Switch-IB, and ConnectX-3/ConnectX-3 Pro VPI adapters with QSFP+ ports. Not a QSFP28 or QSFP56 cable. Not a breakout cable. Cannot be re-terminated; the 1.5m length is fixed. 56Gb/s mode requires Mellanox-rated ports on both ends; third-party hosts may only run at 40Gb/s with this cable. Verify physical port airflow clearance at 1.5m bulk diameter.

Frequently Asked Questions (FAQ)

Q. What is the MC2207130-0A1?
The MC2207130-0A1 is a 1.5m passive copper VPI DAC with QSFP+ connectors, rated up to 56Gb/s (FDR).

Q. Is this a splitter cable?
No. It is a straight 1-to-1 QSFP+-to-QSFP+ point-to-point assembly.

Q. Will T.E.S IT-SOLUTIONS confirm the configuration of MC2207130-0A1 before shipping?
Yes. T.E.S IT-SOLUTIONS (tes-itsolutions.com) inspects each unit and verifies vendor markings before dispatch from EU stock.
