40Gigabit
40 Gigabit Ethernet, often abbreviated as 40GbE, is a networking standard that provides a data transfer rate of 40 gigabits per second. It is a significant upgrade over previous Ethernet standards like 10 Gigabit Ethernet, offering a substantial increase in bandwidth. This technology is primarily used in high-performance networking environments such as data centers, high-frequency trading platforms, and high-performance computing clusters where rapid data movement is critical.
The 40GbE standard utilizes multiple lanes of data transmission to achieve its high speed. Typically, it employs
Common physical interfaces for 40GbE include QSFP+ (Quad Small Form-factor Pluggable Plus) transceivers, which are compact
