Buy 200-Gigabit (200G) • 400-Gigabit (400G) • 800-Gigabit (800G) Ethernet Network Cables & Modules for your AI/datacenter network build-outs factory-direct from Amphenol Cables on Demand (CablesOnDemand.com). We stock dozens of popular Direct Attach Copper (DAC) Cable Assemblies and Loopback Adapter Modules that are specifically engineered and optimized for handling all aspects of your 200-Gigabit Ethernet (200GbE/200G Ethernet), 400-Gigabit Ethernet (400GbE/400G Ethernet) and 800-Gigabit Ethernet (800GbE/800G Ethernet) network back-haul traffic links. Choose from a broad array of 200G/400G/800G-capable interconnects, including:

200G/400G/800G Ethernet capable QSFP-DD Cables & Loopback Adapter Modules – QSFP-DD (QSFP Double-Density) is the advanced successor technology to the QSFP28 form factor, which offer up to 8X the throughput (800.0-Gigabits-per-second) of their 100G-rated QSFP28 predecessor. This evolution is made possible first by doubling the data lanes from 4-lanes to 8-lanes, then doubling throughput once again by upgrading from NRZ QSFP-DD 56G (Non-Return-to-Zero PAM2) modulation to advanced QSFP-DD 112G PAM4 modulation. Enjoy your choice of 200G, 400G and 800G QSFP-DD Direct Attach Copper (DAC) Cables, QSFP-DD to 2 x QSFP28/56 “Y” Splitter DAC Cables, as well as QSFP-DD Loopback Adapter Modules.

An alternative 200G/400G/800G Ethernet capable Cable and Loopback Adapter Module IO topology is the OSFP (Octagonal SFP), similar to DSFP, which doubles the connector density by featuring a larger footprint. The large OSFP footprint may compromise max port density, but that size affords it better thermal load capacity than its QSFP-DD cousin. Just like QSFP-DD, OSFP scales the speed capacity up dramatically to 800-Gigabits-per-second because of the increased density, as well as the optional use of advanced OSFP 112G PAM4 modulation. Enjoy your choice of 200G, 400G and 800G OSFP Direct Attach Copper (DAC) Cables as well as OSFP Loopback Adapter Modules.
