Connectivity Solutions for 200G Optical Module

Q1: What is the main difference between NVIDIA MMA1T00-VS and MMA1T00-HS?A1: While both are 200G QSFP56 SR4 modules, the MMA1T00-VS is optimized and coded for Ethernet systems (Spectrum switches/ConnectX-6 EN adapters). The MMA1T00-HS is coded for InfiniBand HDR environments (Quantum switches).


Q2: Does the MMA1T00-VS support multi-speed rate downshifts?A2: No. The MMA1T00-VS is locked natively to 200G PAM4 performance. It does not support downrating or operating at 100G NRZ rates on legacy devices.

Q3: What type of fiber optic patch cord is required for this 200G SR4 module?A3: It uses a Multi-Mode Fiber (MMF) patch cable equipped with an MPO-12 (UPC polish, typically Type-B crossover polarity) connector. It is not compatible with dual-LC fibers.

Q4: Can I use this 200G SR4 module on a standard 100G QSFP28 switch port?A4: No. The 100G QSFP28 uses 25G NRZ electrical lanes and cannot process the 50G PAM4 signals used by this 200G QSFP56 transceiver.

Q5: Is Forward Error Correction (FEC) required to use this module?A5: Yes. In accordance with the IEEE 802.3bs 200GBASE-SR4 standard, the host equipment must have RS-FEC turned on to manage the native signal margins of PAM4 technology.

Q6: Can this module be split into breakout connections?A6: Yes. Because it features a parallel 4-lane VCSEL optics structure, you can use an MPO-12 to 2x QSFP56 breakout cable or an MPO-12 to 4x SFP56 breakout cable to divide the link into 2x 100G or 4x 50G connections, provided your NVIDIA switch port supports splitting.

Q7: What is the maximum transmission distance over multi-mode fiber?A7: The module supports up to 100 meters (328 feet) when utilizing high-quality OM4 multi-mode fiber, and up to 70 meters (229 feet) when utilizing OM3 fiber.

Q8: Does the MMA1T00-VS feature Digital Diagnostics Monitoring (DDM)?A8: Yes. It provides fully compliant SFF-8636 Digital Diagnostic Monitoring allowing real-time tracking of internal temperature, operating voltage, laser bias currents, and transmit/receive power values via the switch OS.

Q9: What happens if I insert a third-party clone of this module into my NVIDIA Spectrum switch?A9: NVIDIA switches utilize advanced firmware validation checks. If a non-genuine or poorly coded module is detected, the switch OS will trigger a flag (e.g., Unsupported Cable) and disable the port to protect signal integrity.
