50-Gigabit (50G) Ethernet • 100-Gigabit (100G) Ethernet Network Cables & Modules

Buy 50-Gigabit (50G) Ethernet • 100-Gigabit (100G) 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, Active Optical Cables (AOC) and Optical Transceiver Modules that are specifically engineered and optimized for handling all aspects of your 50-Gigabit Ethernet (50GbE/50G Ethernet) and 100-Gigabit Ethernet (100GbE/ 100G Ethernet) network back-haul traffic links. Choose from a broad array of 50G/100G-capable interconnects, including:

For 50-Gigabit (50G) Ethernet specifically, we feature new SFP-DD (SFP-DD56 Cable) 50G Direct Attach Copper (DAC) Cables for short 50GBASE-CR (50G Ethernet over Twin-Ax Copper) back-haul links, as well as NEW 50G DSFP (Double SFP Cable) to 2 x 25G SFP28 Direct Attach Copper (DAC) Splitter “Y” Cables for linking new 50G DSFP switch/server ports to prior-gen 25G SFP28 ports. For 100-Gigabit (100G) Ethernet, the QSFP28 (Quad SFP28) is the dominant form-factor. For testing your server/switch QSFP28 ports, we stock the web’s largest variety of QSFP28 100G Loopback Adapter Modules.

Our QSFP28 line-up of 100GBASE-CR compliant (100G Ethernet over Twin-Ax Copper) products extend further still, ready to handle your network’s 100G back-haul traffic, including QSFP28 100G Direct Attach Copper (DAC) Cables, as well as QSFP28 100G to 4 x SFP28 25G Direct Attach Copper (DAC) Splitter Cables, both available in lengths up to 5-meters (16.4ft) for inter-rack and intra-rack links. Finally, for extended link distances up to 100-meters/330-feet, we offer 100GBASE-SR Short Range QSFP28 Optical Transceiver Modules and for link lengths up to 10-km, we stock 100GBASE-LR Long Range QSFP28 Optical Transceiver Modules. An excellent option where wire flexibility and wire clearance are paramount is our QSFP28 100G Active Optical Cable (AOC).
