Page 3: Introduction
1 Introduction NVIDIA MFA7U10 is an OSFP to 2x QSFP56, 400Gb/s to 2 x 200Gb/s Active Optical splitter Cable (AOC) designed for connecting NVIDIA NDR and 400GbE Ethernet switches with OSFP cage, to legacy 2 HDR/200GbE switch/HCA QSFP56 cages. The cable is compliant with SFF-8665 for the QSFP56 pluggable solution. It provides connectivity between system units with an OSFP 400Gb/s connector on one side and two separate QSFP56 200Gb/s connectors on the other side, such as a switch and two servers. - Page 4 • Single 3.3V power supply • 5W Max power consumption for QSFP56 ends • 10W Max power consumption for the OSFP head end • Hot pluggable • RoHS compliant • SFF-8636 compliant I C management interface...

2.2.1 QSFP56 Module Pad Layout 2.3 Control Signals (OSFP) This AOC has CMIS 4.0 (check for update, e.g. to CMIS 5) compliant management interface and OSFP 4.1 (check for update) compliant form factor and interfaces. This implies that the control signals shown in the pad layout are implemented with the following functions: Name Function... -
Page 9: Control Signals (Qsfp)
2.4 Control Signals (QSFP) This AOC is SFF-8636 compliant. This means that the control signals shown in the pad layout support the following functions: Name Function Description ModPrsL Output Module Present pin, grounded inside the module. Terminated with pull-up in the host system. Asserted low when the transceiver is inserted, whereby the host detects the presence of the transceiver. - Page 10 • Tx/Rx CDR control by default enabled for 100 GbE operation, disable it for 40G operation Digital Diagnostic Monitoring (DDM): • Rx receive optical power monitor for each lane • Tx transmit optical power monitor for each lane • Tx bias current monitor for each lane •...
