This video explains the capabilities of QSFP28 modules and how they enable 100 Gbps Ethernet connections using fiber optic cables. It demonstrates a real-world speed test between two computers, showing practical data transmission rates, and discusses the differences in hardware capacity impacting performance. #QSFP28 #EthernetSpeed
Keypoints :
- The QSFP28 module allows for 100 gigabit per second Ethernet connectivity using fiber optic cables.
- An MO connector is used to connect fiber cables directly to the QSFP28 module.
- The setup involves two computers connected at 100 Gbps, with one acting as a server and the other as a client for testing.
- Speed tests conducted with iperf software show real-world data transfer speeds around 45-47 Gbps.
- Performance is influenced by the older hardware of the computers used in the test, not the network cards.
- More modern computers would likely achieve higher speeds than those demonstrated in the test.
- In larger environments like data centers, speeds of 200, 400, or even 800 Gbps are common today.
