The MC2309124-007 is a passive copper hybrid cable (QSFP-to-SFP+ breakout cable) for 10GbE Ethernet at 7-meter reach. 24 AWG copper conductors — the heavier gauge is required to maintain signal integrity at 7-meter passive copper reach for 10GbE. QSFP connector on the switch side; SFP+ connector on the server or storage side. This cable IS a QSFP-to-SFP+ passive copper hybrid for 10GbE at 7m. It is NOT an optical cable, NOT a QSFP-to-QSFP DAC, and NOT rated for 25GbE, 40GbE, or 100GbE. This is original NVIDIA Mellanox hardware sold by T.E.S IT-SOLUTIONS (tes-itsolutions.com) — not a compatible or third-party alternative. Condition: refurbished.
Engineering
The MC2309124-007 delivers 10Gb/s full-duplex over 7 meters of 24 AWG passive copper. The 24 AWG heavy-gauge conductor (compared to 30 AWG in shorter series variants) is necessary to reduce signal loss at 7-meter passive copper reach for 10GbE. QSFP connector on the switch/fabric side; SFP+ connector on the server or storage side. No active components — zero cable power draw. 7 meters is at the practical upper limit of passive copper capability for 10GbE QSFP-to-SFP+ hybrid cables; beyond this distance, active copper or optical solutions are required.
Deployment
Used for 10GbE server-to-switch connections where servers and the top-of-rack switch are separated by 5–7 meters — typical for full-height rack deployments where servers at the bottom of the rack connect to a top-of-rack switch and standard 1m–3m cables are insufficient. Common in VMware ESXi and Hyper-V environments, iSCSI SAN fabric construction, and 10GbE NAS access-layer cabling in deep server racks. The MC2309130 series (QSFP-to-SFP+, 30 AWG) covers 0.5m–3m reaches; the MC2309124-007 fills the 7m segment with heavier 24 AWG copper.

Compatibility
Compatible (QSFP end) with Mellanox SN2010, SN2100, SN2700 and other 10GbE/QSFP switches. Compatible (SFP+ end) with 10GbE SFP+ NICs including NVIDIA ConnectX-3, ConnectX-4 Lx, and third-party SFP+ adapters. NOT compatible with QSFP-to-QSFP point-to-point links. NOT suitable for 25GbE, 40GbE, or 100GbE. NOT compatible with 10GBASE-T RJ45. 7 meters is the maximum rated passive copper reach for this cable; beyond 7m, active fiber (AOC) or active copper (ACC) SFP+ solutions are required. For shorter reaches: MC2309130-003 (3m, 30 AWG) and MC2309130-002 (2m, 30 AWG) are lighter and more flexible alternatives.
