NVIDIA Mellanox MC2207910-005 QSFP+ Active Fiber Cable, 5m, FDR/56GbE VPI: This is a 5-meter active optical cable (AOC) terminated with QSFP+ connectors on both ends. The cable is rated for InfiniBand FDR (56Gb/s) and 56 Gigabit Ethernet through Mellanox VPI. It is an active fiber assembly with integrated electro-optics and link LEDs at each connector — not a passive copper DAC and not a transceiver-with-detachable-patch-cord. This is a refurbished unit.
Engineering Context
The MC2207910-005 carries four lanes of 14Gb/s NRZ signaling (4x14Gb/s = 56Gb/s aggregate) over multi-mode optical fiber. As an active assembly, it eliminates the dirty fiber end-face and connector mating issues typical of separately purchased transceivers and patch cords. The integrated link-status LEDs assist with rapid fault localization in dense cable trays. The 5-meter length suits intra-rack and adjacent-rack routing where copper FDR DACs become bulky.
Deployment & Use Cases
Mellanox SX6000-series FDR switch interconnects to ConnectX-3 / ConnectX-3 Pro / ConnectX-4 host adapters. 56GbE Ethernet uplinks where copper bundles exceed cable tray weight limits. HPC cluster compute-to-storage links at FDR. Adjacent-rack patching where EMI immunity and lighter cabling are preferred over passive copper.
Technical Specifications
OEM: NVIDIA Mellanox
Part Number: MC2207910-005
Form Factor: QSFP+ to QSFP+ (Point-to-Point)
Cable Type: Active Optical Cable (AOC)
Length: 5 meters
InfiniBand Rate: FDR (56Gb/s, 4x14G NRZ)
Ethernet Rate: 56GbE
Protocol: VPI (InfiniBand and Ethernet)
Indicators: Integrated link-status LEDs per connector
Condition: Refurbished — Tested by T.E.S IT-SOLUTIONS
Compatibility & Hard Constraints
Compatible with Mellanox QSFP+ ports on SX6000-series switches and ConnectX-3 / ConnectX-3 Pro / ConnectX-4 (in QSFP+ mode) adapters running FDR or 56GbE. Not compatible with QSFP28 EDR ports as a 100Gb/s cable — link rate is capped at FDR/56GbE. Not a breakout cable; QSFP+-to-QSFP+ only. Fixed 5-meter length. Active assembly draws power from the host port; verify host port power budget supports active QSFP+ optics.
