Is signal latency higher on 30m compared to 3m?

The additional fiber flight time is approximately 135ns, which is negligible for most applications compared to switch hop latency. The active electronics add the same latency regardless of cable length.

Can this cable connect a 200G switch to two 100G servers?

Yes, that is the primary design purpose. It splits a single 200G QSFP56 switch port into two HDR100 (100Gb/s) server connections, doubling port density.

Is this cable hot-swappable?

Yes, it is hot-pluggable. However, gracefully shut down the link before removal to prevent packet loss.

NVIDIA Mellanox MFS1S50-H030V 200Gb/s to 2x100Gb/s QSFP56 Active Optical Splitter Cable, 30m: This is a 30-meter active optical cable (AOC) that splits a single 200Gb/s QSFP56 port into two 100Gb/s (HDR100) QSFP56 endpoints. The cable uses VCSEL optics for signal transmission and is a fixed-length integrated assembly — not a transceiver with detachable patch cords. This is a refurbished unit.

Engineering Context

At 30 meters, passive copper is physically impossible for 200Gb/s signaling. The MFS1S50-H030V provides the bandwidth density of HDR100 with optical reach, at lower power and cost than pluggable transceiver + fiber combinations. The AOC delivers deterministic latency and complete EMI immunity, ensuring reliable transmission even through electrically noisy overhead cable trays spanning multiple rack rows. The source end consumes up to 5W and each endpoint up to 3.5W.

Deployment & Use Cases

Inter-row connectivity: connecting Quantum HDR switches to compute racks in different cooling zones. Connecting centralized storage appliances to distant GPU compute nodes. Doubling switch port density by splitting 200G QSFP56 ports into two HDR100 endpoints. Non-blocking fabric topologies in warehouse-scale data centers requiring 30m reach.
