200G QSFP56 Breakout InfiniBand HDR Overview
The 200G QSFP56 Breakout InfiniBand HDR category contains two breakout cable assemblies: one passive DAC and one AOC. Both models divide one 200G QSFP56 connection into two 100G QSFP56 branches for InfiniBand HDR links. Available in lengths from 1m to 50m, the series supports connections with QM8700 and QM8790 switches and compatible MCX653105A and MCX653106A adapter models in supercomputing and large-scale systems.
Q200-2Q-HDR-C is a 1–3m passive copper breakout cable that divides one 200G QSFP56 interface into two 100G QSFP56 connections. Each branch carries 100G, supporting short-distance InfiniBand HDR links between compatible switches, network adapters, and computing systems.
Q200-2Q-HDR-A is a 1–50m active optical breakout cable connecting one 200G QSFP56 port to two 100G QSFP56 branch ports. Compliant with QSFP-MSA and 200GBASE-SR4 specifications, it supports NVIDIA QM8700/QM8790 switches and compatible MCX653105A or MCX653106A adapters in supercomputing and large-scale InfiniBand systems.
FAQ
- How does the 200G QSFP56 Breakout InfiniBand HDR category divide bandwidth between the 200G connector and the two branch connectors?
It provides one 200Gb/s QSFP56 connection and two 100Gb/s QSFP56 branches. In HDR operation, the 200G side carries four 50Gb/s lanes, while each branch uses two 50Gb/s lanes, preserving a combined branch bandwidth of 200Gb/s.
- What is the main transmission-medium difference between Q200-2Q-HDR-C and Q200-2Q-HDR-A?
Q200-2Q-HDR-C uses passive copper twinax, while Q200-2Q-HDR-A uses active optical transmission. Both models provide the same one-to-two breakout configuration with one 200G QSFP56 end and two 100G QSFP56 branch ends.
- What cable lengths are available for Q200-2Q-HDR-C and Q200-2Q-HDR-A?
Q200-2Q-HDR-C is available in lengths from 1m to 3m. Q200-2Q-HDR-A extends the available connection range from 1m to 50m, while retaining the same 200G-to-2×100G QSFP56 breakout structure.
- Can Q200-2Q-HDR-C be used as a straight-through 200G QSFP56-to-QSFP56 cable?
No. Q200-2Q-HDR-C is a breakout cable rather than a straight-through assembly. Its single 200G QSFP56 end connects to two separate 100G QSFP56 branch ends, so neither branch provides a native 200G connection.
- How can Q200-2Q-HDR-C or Q200-2Q-HDR-A expand HDR100 connectivity on NVIDIA QM8700 and QM8790 switches?
Each cable converts one 200G QSFP56 switch port into two 100G HDR100 branches. QM8700 and QM8790 systems provide 40 HDR 200G QSFP56 interfaces and can support up to 80 HDR100 connections through compatible breakout configurations.
- Can Q200-2Q-HDR-A connect QM8700 or QM8790 switches to compatible MCX653105A and MCX653106A adapters?
Yes. Q200-2Q-HDR-A supports connections involving QM8700 or QM8790 switches and compatible MCX653105A or MCX653106A adapters. Each branch operates at 100Gb/s and terminates on a compatible QSFP56 port operating in HDR100 mode.
- Does Q200-2Q-HDR-A require separate optical transceivers or detachable fiber patch cords?
No. Q200-2Q-HDR-A is an integrated active optical breakout cable with QSFP56 connectors attached at all three ends. It does not require separate optical modules or external fiber patch cords for the 200G-to-2×100G connection.
- Is Q200-2Q-HDR-A specified for both QSFP-MSA and 200GBASE-SR4 compliance?
Yes. Q200-2Q-HDR-A is specified as compliant with QSFP-MSA and 200GBASE-SR4 while functioning as a 200G QSFP56 to 2×100G QSFP56 InfiniBand HDR active optical breakout cable.
