Description
The NVIDIA MCA4J80-N003-FLT is the flat-top version of the 3-meter MCA4J80 active copper cable. It links two 800Gb/s (2x 400Gb/s) twin-port OSFP ports using 8 channels of 100G-PAM4. A pre-emphasis equalizer IC in each end keeps latency very low and power at a maximum of 1.5W per end. Its firmware supports both InfiniBand and Ethernet and enables the right protocol automatically. Flat tops on both ends suit devices without finned OSFP cages, such as liquid-cooled systems.
