Description
NVIDIA Mellanox MC2609130-003 40GbE QSFP+ to 4x10GbE SFP+ Hybrid Passive Copper DAC, 3m: This is a 3-meter passive copper hybrid breakout cable that splits a single 40GbE QSFP+ port into four independent 10GbE SFP+ links. The QSFP+ end carries 4 lanes of 10GbE NRZ that the cable physically separates into four SFP+ heads. This is a passive direct-attach copper (DAC) assembly with no active electronics, not an active copper cable and not a fiber AOC. This is a refurbished unit.
Engineering Context
The MC2609130-003 is a 1-to-4 breakout DAC: the upstream QSFP+ port aggregates 4x10G lanes, and the cable presents each lane as a discrete SFP+ pluggable. Because the cable is passive copper, the upstream switch must support 4x10G breakout mode on its 40GbE QSFP+ port (sometimes called "split mode" or "4-channel mode") and the downstream devices must accept SFP+ DAC. No power is drawn at either end. Insertion loss budget is consistent with short reach passive copper at 10GBASE-CR.
Deployment & Use Cases
Aggregating four 10GbE servers (legacy 10G NICs) into a single 40GbE switch port to conserve switch panel density. ToR uplink fan-out for 1U servers with SFP+ adapters connecting up to a 40GbE aggregation switch. Migration deployments where 40GbE switching is in place but endpoints remain on 10GbE. Lab and test environments needing four independent 10GbE links from a single QSFP+ test instrument. Storage shelves with SFP+ host ports homed onto a 40GbE distribution layer.

Compatibility & Hard Constraints
Requires a 40GbE switch port that explicitly supports 4x10G breakout mode (not all 40GbE QSFP+ ports do). NOT compatible with 100GbE QSFP28 ports for breakout to 25GbE — a different cable (MCP7F00-A series) is required for that scenario. NOT compatible as a 1-to-1 40G-to-40G interconnect; this is a breakout-only cable. NOT an InfiniBand cable; designed for Ethernet protocol only. NOT a fiber cable; do not use for runs longer than 3m or where EMI immunity is required. The four SFP+ heads cannot be aggregated back into a single 40G link by another cable.
Frequently Asked Questions (FAQ)
Q. What is the MC2609130-003?
The MC2609130-003 is a 3m passive copper breakout cable: one QSFP+ head at 40GbE breaks out into four SFP+ legs at 10GbE each.
Q. Does the switch need special configuration?
Yes. The head port must be configured for 4x10GbE breakout mode.
Q. Will T.E.S IT-SOLUTIONS confirm the configuration of MC2609130-003 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.
