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).
