What is the per-cable length and data rate of the MC2210126-005?

Each MC2210126-005 cable is 5 meters with QSFP+ connectors on both ends, rated for 40Gb/s Ethernet (4 × 10Gb/s NRZ).

Is the MC2210126-005 a passive or active cable, and what is its reach class?

It is a passive copper DAC, not an AOC and not active copper. Passive copper at 40GbE is limited to short reach (5m is near the upper end). For runs beyond passive reach, use an AOC like the MFA1A00 series.

What does the lot of 4 include and how is it tested?

The listing ships 4 × MC2210126-005 cables, each link-tested by T.E.S IT-SOLUTIONS before shipment. See https://www.tes-itsolutions.com/ for support details.

NVIDIA Mellanox MC2210126-005 QSFP+ Passive Copper Cable, 5m (Lot of 4): This listing is a lot of 4 × MC2210126-005 passive direct-attach copper (DAC) cables, each 5 meters long with QSFP+ connectors on both ends, rated for 40GbE Ethernet at 4 × 10Gb/s. This is a refurbished passive copper DAC bundle — it is NOT an active optical cable, NOT an active copper cable, and NOT length-flexible (5m fixed per cable).

Engineering Context. The MC2210126-005 is a passive twinaxial copper DAC with no powered electronics, terminated in QSFP+ (SFF-8436) on both ends. It carries 4 × 10Gb/s NRZ lanes for 40GbE aggregate. As a passive cable it consumes essentially no port power and adds no additional latency beyond signal propagation, making it ideal where reach is short and budget is tight.

Deployment & Use Cases. Typical deployments include in-rack and adjacent-rack 40GbE leaf-to-server connections, top-of-rack switch to ConnectX adapter links (Mellanox MSX1036 / MSN2700 leaf to ConnectX-3/4 NICs), and 40GbE inter-switch trunks within the same row. The lot of 4 supports populating a small cluster or maintaining cold spares alongside production cables.

Compatibility & Constraints. Works with NVIDIA Mellanox QSFP+ ports on ConnectX-3/4 adapters and SwitchX/SwitchX-2/Spectrum switches at 40GbE. This MPN is rated for 40GbE Ethernet — InfiniBand support is not specified for this SKU; for guaranteed IB QDR/FDR10 use an IB-rated copper DAC. Passive copper has reach limits — 5m is at the upper end of typical 40GbE passive DAC; for longer runs use AOC (such as MFA1A00 series) or active copper. Listing is sold as a lot of 4 cables; individual cables are not separated.

Why TES. Sourced and bench-tested by T.E.S IT-SOLUTIONS. Each cable in the lot is link-tested end-to-end before shipment. Handling time 1–3 business days from our EU stock.
