Networking MFA7A50 is a VCSEL-based (Vertical-Cavity Surface-Emitting Laser), cost-effective, 100GbE to 4x25GbE, active optical breakout cable designed for use in 100GbE Ethernet systems. The MFA7A50 cable is compliant with SFF-8402 for the SFP28 ends and with SFF-8665 for the QSFP28 end. It provides connectivity between system units with a QSFP28 port on one side and up to four different SFP28 ports on the other side, such as a switch and four servers. The cable connects data signals from each of the 4 mmF (Multi-Mode Fiber) pairs on the QSFP28 end to the single pair of each of the SFP28 ends. Each QSFP and SFP port comprises an EEPROM providing product and status monitoring information that can be read by the host system. NVIDIA's unique, quality, active, fiber, cable solutions provide power-efficient connectivity for data center interconnects. They enable higher port bandwidth, density, and configurability at a low cost and reduced power requirements in the data centers. Rigorous cable production testing ensures the best out-of-the-box installation experience, performance, and durability.
