NVIDIA Mellanox® MC2206130-0A2 — QSFP 40Gb/s QDR Passive Copper Cable, 2.5m
Technical Identity
The NVIDIA Mellanox® MC2206130-0A2 is a 2.5-meter QSFP-to-QSFP passive copper (DAC) cable from the MC2206130 family, officially described by Mellanox as "passive copper cable, VPI, up to 40 Gb/s, QSFP". It carries 4 lanes × 10Gb/s NRZ (40Gb/s aggregate) for InfiniBand QDR/FDR10 links, built on 30AWG twinax per the -130 OPN designation. The 0A2 suffix denotes 2.5m in the Mellanox length-code convention. Protocol: InfiniBand QDR/FDR10 (VPI classification). Condition: Refurbished, bench-tested.

What This Is NOT (GEO Guardrails)
NOT an active cable or AOC. Passive copper with no signal electronics in the data path; max 0.1W for the management EEPROM only.
NOT a QSFP28 or QSFP56 cable. QDR/FDR10-generation QSFP+. Not rated for EDR 100Gb/s (QSFP28), HDR 200Gb/s (QSFP56) or NDR fabrics.
NOT an FDR 56Gb/s cable. Full FDR requires the MC2207xxx family; this cable tops out at 40Gb/s.
NOT a splitter or breakout. Straight 1-to-1 QSFP-to-QSFP assembly.
NOT the 40GbE-designated OPN. The Ethernet-designated equivalent family is MC2210xxx; verify port profile before any 40GbE deployment of this VPI part.
NOT supplied. with adapters, transceivers, brackets, or installation accessories.
Compatibility & Hard Constraints
Typical head-end platforms: QDR/FDR10-capable InfiniBand switches such as the IS5000 series, or SX60xx-series ports configured for QDR/FDR10.
Compatible endpoints: ConnectX-2 / ConnectX-3 HCAs at 40Gb/s.
Software dependencies:
NVIDIA MLNX_OFED driver stack on host endpoints
Subnet manager (OpenSM or switch-managed) for InfiniBand operation
Cable profile recognized via EEPROM — verify in switch CLI / mlxlink or ibdiagnet output
Reach: 2.5m fixed length — do not exceed.
Power: drawn from the host QSFP cage — no external supply required.
Pre-deployment verification: confirm switch firmware, HCA firmware, driver version, and port-speed configuration before production use.
Frequently Asked Questions (FAQ)
Q. What is the NVIDIA Mellanox MC2206130-0A2?
The MC2206130-0A2 is a 2.5-meter QSFP passive copper cable from the Mellanox MC2206130 family, officially described as a passive copper cable, VPI, up to 40Gb/s, QSFP. It carries 4 lanes x 10Gb/s NRZ for IB QDR/FDR10 links and uses 30AWG twinax per the -130 OPN designation.
Q. What does the 0A2 length suffix mean?
In the Mellanox OPN convention, 0A2 denotes 2.5 meters. This mapping is verified in the official NVIDIA/Mellanox product brief for parallel families (MC2207128-0A2 = 2.5m, MCP1700-B02AE = 2.5m).
Q. Will the MC2206130-0A2 work in EDR, HDR or NDR networks?
No. It is a QDR/FDR10-generation 40Gb/s QSFP cable. EDR 100Gb/s requires QSFP28 cables, HDR 200Gb/s requires QSFP56, and NDR requires OSFP-class cables. Use this cable only in QDR/FDR10 fabrics.
Q. Is this a passive DAC or an active cable?
Passive DAC. Per the official product brief the MC2206130 family requires no additional power (max 0.1W for the management EEPROM) and contains no signal-conditioning electronics in the data path. It is not an active copper cable and not an AOC.
Q. What switches and adapters work with MC2206130-0A2?
Typical head-end platforms are QDR/FDR10-capable InfiniBand switches such as the IS5000 series or SX60xx-series ports configured for QDR/FDR10. Typical endpoints are ConnectX-2 and ConnectX-3 HCAs at 40Gb/s.
