    IB networking method using active optical fiber or copper cable

    InfiniBand (IB) is a high-performance networking technology initially developed to address the limitations of traditional Ethernet and fiber channels, so it was created with high throughput, low latency, and scalability in mind. InfiniBand cables come in various types to accommodate different connectivity requirements and environments. Some of the most common types include active optical cable (AOC), direct attach copper cable (DAC), and active copper cable (ACC). InfiniBand was an early adopter of AOC cables due to these advantages over physically separate transceivers: The optical fibers can be perfectly aligned in the factory and their. InfiniBand (IB) technology is a critical enabler of faster, more efficient data movement, and it is used in fields like high-performance computing (HPC), artificial intelligence (AI), and machine learning (ML). The effectiveness and speed of the system are contributed by each wire in the bunch, which supports communication with high bandwidth. This delivers a convenient all-in-one solution, built into one cable.
