NVIDIA Mellanox MCP1700-F003D 56Gb/s VPI QSFP+ Passive Copper Cable, 3m: This is a 3-meter passive direct-attach copper (DAC) cable engineered for FDR InfiniBand (56Gb/s) and 56GbE Ethernet point-to-point interconnect using Mellanox VPI (Virtual Protocol Interconnect). The cable terminates in QSFP+ connectors at both ends and requires no external power. This is a fixed-length passive assembly, not an active or optical cable. This unit is brand new.
Engineering Context
The MCP1700-F003D is a passive copper cable optimized for short-reach, intra-rack interconnects between FDR InfiniBand or 56GbE-capable switches and adapters. As a passive cable it draws no operational power and adds no signal regeneration latency. The QSFP+ form factor carries 4 lanes of 14Gb/s signaling for the aggregate 56Gb/s rate. The 3-meter length sits well within the passive copper electrical reach budget for FDR. The cable has a yellow pulltab for fast lane identification.
Deployment & Use Cases
Top-of-rack to compute node connections in FDR InfiniBand HPC clusters. Aggregation links between FDR switches inside a single rack. 56GbE Ethernet links between Mellanox VPI switches operating in Ethernet mode and ConnectX-3 Pro adapters. Storage-to-compute interconnect in InfiniBand fabrics where short copper reach is sufficient.
Technical Specifications

Cable Type: Passive Direct-Attach Copper (DAC)
Length: 3m
Protocol: InfiniBand FDR / 56GbE Ethernet (VPI)
Pulltab: Yellow

Condition: New — Tested by T.E.S IT-SOLUTIONS
Compatibility & Hard Constraints
Compatible with NVIDIA Mellanox FDR InfiniBand switches (SX6000 series) and ConnectX-3, ConnectX-3 Pro VPI adapters. Compatible with switches and adapters that operate in 56GbE Ethernet VPI mode. Not compatible with EDR (100Gb/s) or HDR (200Gb/s) ports — for those rates, use MCP1600 (QSFP28) or MCP1650 (QSFP56) series cables. Reach is bounded by the fixed 3-meter length; this is a direct QSFP+ to QSFP+ cable and does not support breakout.
