QSFP28 to QSFP28 100 Gbps DAC
100G Passive copper cables are the most common type of 100G DAC cable and are usually used for short distances. They have a low price point and deliver good performance, but their distance range of 5 meters limits them.
100G active copper cables are a newer technology and are becoming more efficient for their increased distance range of up to 10 meters. They have a higher price point but offer better performance for their increased capacity.
Another type is a hybrid 100G DAC cable. This type of cable comprises different connectors and data rates on both ends of the cable. For example, one end might be an SFP28 for 25G Ethernet, and the other could be a QSFP28 for 100G Ethernet. This cable is helpful for those who need to interconnect the switch ports.
When choosing a 100G DAC cable, it is crucial to consider the length of the run, the data rate of the devices, and the budget. For short runs, passive copper cables are a good option. Active copper cables might be a better option for longer runs or devices requiring high data rates.
No matter what type of 100G DAC cable you choose, you can be sure it will provide a fast and reliable connection.
