The MC2207312-020 is a QSFP Active Fiber Cable (AFC) for VPI (Virtual Protocol Interconnect) environments supporting InfiniBand FDR at 56Gb/s and 40GbE Ethernet over 20 meters. QSFP connectors on both ends. This is a long-reach AFC variant in the MC2207312 series, designed for inter-rack connections where the shorter MC2207310 series (3m and 6m) are insufficient. This cable IS a QSFP-to-QSFP active fiber VPI cable for FDR InfiniBand and 40GbE at 20m reach. It is NOT a passive copper cable, NOT compatible with QSFP28 (EDR/100GbE) ports, and NOT compatible with SFP+ interfaces. 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 MC2207312-020 uses active optoelectronic transceivers at each QSFP housing to transmit FDR InfiniBand or 40GbE data over multi-mode optical fiber at 20-meter reach — far exceeding the passive copper limit (~2.5m at FDR). Each end draws power from the host QSFP slot. VPI dual-protocol: InfiniBand FDR (56Gb/s, 4×14Gb/s lanes) or 40GbE Ethernet, determined by host adapter configuration. Hot-swappable. The MC2207312 series is designed for longer reach than the MC2207310 series (3m, 6m) — the MC2207312 handles the 10m–30m reach range.
Deployment
Used for FDR InfiniBand or 40GbE inter-rack connections requiring 15–20 meter reach — typical for connecting switch rows across different data center hot aisles, spanning two or more adjacent rack rows, or cabling between a spine switch in one row and leaf switches in another. Common in large-scale HPC clusters (GROMACS, NAMD, Amber, weather modeling), university supercomputing centers, and data centers with distributed FDR InfiniBand fabric where MC2207310-006 (6m) is insufficient but long-haul single-mode fiber is not required. T.E.S IT-SOLUTIONS also stocks the MC2207310-003 (3m) and MC2207310-006 (6m) shorter VPI AFCs.

Compatibility
Compatible with Mellanox FDR InfiniBand QSFP switches: SX6036, IS5100. Compatible with 40GbE QSFP Ethernet switches: Mellanox SN2100 series. Compatible with NVIDIA ConnectX-3 VPI and ConnectX-4 VPI QSFP adapters. NOT compatible with QSFP28 (EDR InfiniBand 100Gb/s or 100GbE) ports. NOT a passive copper cable: requires host port power. NOT compatible with SFP+ interfaces. Shorter VPI AFC alternatives from T.E.S IT-SOLUTIONS: MC2207310-003 (3m), MC2207310-006 (6m). For EDR InfiniBand (100Gb/s) at 20m, QSFP28 active fiber cables are required rather than the MC2207312-020.
