What is the optical latency over a 100m FDR AOC?

Optical latency over multi-mode fiber is approximately 5 ns per meter, so the MC2207310-100 introduces about 500 ns of end-to-end propagation delay. This is generally negligible for HPC workloads compared to switch and HCA latencies.

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

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

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 MC2207310-100 QSFP+ 56Gb/s 4X FDR InfiniBand Active Optical Cable, 100m: This is a 100-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

At 100 meters, the MC2207310-100 sits at the upper reach of standard FDR InfiniBand AOCs and is intended for inter-room or building-floor InfiniBand fabric extensions. FDR encoding is 64b/66b across four 14Gb/s lanes, yielding the 56Gb/s 4X FDR aggregate rate. Optical latency over the cable is approximately 500 ns end-to-end (5 ns/m of multi-mode fiber). The integrated termination eliminates per-end fiber cleaning and connector loss budgeting that would be required if pairing discrete SR4 transceivers with an MPO patch cord of equivalent reach.

Deployment & Use Cases

Inter-room InfiniBand fabric runs between compute and storage halls. HPC cluster expansions where FDR spine fabric must reach a remote rack row. Lustre and GPFS storage backbone connections between distant tiers. SX6036 and SX6025 FDR switch uplinks across data hall partitions. Long-reach connections to remote ConnectX-3 FDR HCAs.

Compatibility & Hard Constraints

Compatible with Mellanox SX6000 series FDR InfiniBand switches (SX6036, SX6025, SX6018) and ConnectX-3 FDR HCAs. The MC2207310-100 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 100m length; not field-terminable. Cable tray weight and bend-radius planning required at this length.
