Know before you buy
Yes, this OptoSpan cable is specifically engineered to be a direct replacement for the Mellanox MC2210128-003. It is individually serialized and adheres to QSFP MSA standards to ensure seamless interoperability with your existing Mellanox switches and servers.
This cable is designed for short-reach, point-to-point connections within a rack or between adjacent racks. At 3 meters (approximately 9.84 feet), it provides reliable 40Gbps performance without the signal degradation associated with longer copper runs.
No, this is a passive Direct Attach Cable (DAC) that functions as a plug-and-play solution. Once connected, your equipment should automatically recognize the link, provided the ports are configured for 40GbE or InfiniBand speeds.
This copper DAC is significantly more energy-efficient than active optical cables or standard transceivers. With a typical power consumption of just 0.02 watts, it helps reduce the overall heat and power load in high-density data center environments.
Yes, the cable is versatile and supports both 40 Gigabit Ethernet and InfiniBand protocols. It utilizes four independent full-duplex channels to maintain high data integrity across both types of network architectures.
