Why use an AOC instead of a copper DAC for 50m?

Passive copper QSFP+ DACs are typically reach-limited to 5-7m at FDR rates. At 50 meters, an active optical cable is the only practical QSFP+ point-to-point option that maintains FDR signal integrity without external transceivers and patch cords.

Will the MC2207310-50 negotiate to EDR (100Gb/s) or HDR (200Gb/s)?

No. The MC2207310-50 is QSFP+ at FDR rates and is not a QSFP28 or QSFP56 cable. It does not negotiate to EDR or HDR. For higher rates, use the appropriate MFA1A00 (EDR/100GbE) or MFS1S00 (HDR) AOC family.

What condition are these cables in?

All units are refurbished and tested by T.E.S IT-SOLUTIONS for FDR link-up and connector condition before shipment. See https://www.tes-itsolutions.com for warranty terms.

NVIDIA Mellanox MC2207310-50 QSFP+ 56Gb/s 4X FDR InfiniBand Active Optical Cable, 50m: This is a 50-meter active optical cable engineered for 56Gb/s 4X FDR InfiniBand point-to-point interconnect over multi-mode fiber. The cable terminates in QSFP+ connectors on both ends and uses 64b/66b line encoding across four 14Gb/s lanes. This is a fixed-length integrated assembly, not a transceiver pair with a detachable patch cord. This is a refurbished unit.

Engineering Context

FDR InfiniBand at 56Gb/s 4X requires 64b/66b encoding (versus 8b/10b on QDR), which improves usable throughput per lane. At 50 meters, the MC2207310-50 covers cross-row and inter-rack runs that exceed the reach of passive copper QSFP+ DACs (typically capped at 5-7m). The integrated optics eliminate fiber end-face cleaning, MPO patch cord variability, and transceiver insertion loss budgeting. Latency over the optical path is approximately 250 ns per 50 meters of fiber.

Deployment & Use Cases

Cross-row InfiniBand fabric runs in HPC clusters running OpenMPI or Intel MPI. Lustre and GPFS storage backbone connections between compute and storage tiers. Spine-leaf InfiniBand topologies where spine-to-leaf reach exceeds passive copper. SX6036 and SX6018 FDR switch interconnects. Long-reach connections to ConnectX-3 FDR HCAs in remote racks.

Technical Specifications

OEM: NVIDIA Mellanox
Part Number: MC2207310-50
Form Factor: QSFP+ to QSFP+ (Point-to-Point)
Data Rate: 56Gb/s 4X FDR InfiniBand
Cable Type: Active Optical Cable (AOC)
Length: 50m
Lanes: 4 x 14Gb/s
Encoding: 64b/66b
Protocol: InfiniBand FDR
Condition: Refurbished - Tested by T.E.S IT-SOLUTIONS

Compatibility & Hard Constraints

Compatible with Mellanox SX6000 series FDR InfiniBand switches (SX6036, SX6025, SX6018) and ConnectX-3 FDR HCAs. The MC2207310-50 is QSFP+ at FDR rates; it is not a QSFP28 cable and will not negotiate to EDR (100Gb/s) or HDR (200Gb/s). On ConnectX-3 VPI cards configured for 40GbE, the cable will operate at 40GbE QSFP+ rates instead of 56Gb/s FDR; reach and link behavior at 40GbE depend on the host adapter firmware. Fixed 50m length; not field-terminable.
