Applications
Built for InfiniBand HDR fabrics, HPC clusters and AI computing networks, this QSFP112 module carries 425Gbps (4x106.25Gb/s) over MMF up to 30m@OM3/50m@OM4 per link. With its MPO-12/APC optical interface, the module works directly with the MMF infrastructure already installed in most facilities. For networks standardized on NVIDIA/Mellanox InfiniBand hardware, it is a drop-in equivalent of the MMA1Z00-NS400. The link runs 4x100G-PAM4 modulation, which keeps it aligned with current 400G switch silicon.
Standards and Compatibility
Compliance: QSFP112 MSA, CMIS Rev5.0, IEEEdf-2024. For projects standardized on NVIDIA/Mellanox InfiniBand hardware, this product replaces the MMA1Z00-NS400 directly, with identical fit and function. Every unit's EEPROM coding and link behavior are verified on real host equipment in our lab, so what arrives at your site is ready to use.
Ordering Information
Order this product as QSFP112-SR4-400G. Common models are stocked for fast dispatch. We can supply the module with neutral or customer-branded labels, and compatibility coding for a specific equipment vendor can be added at no extra process step.
Quality Assurance
Before any product leaves our factory it goes through optical performance testing, compatibility verification on real switch platforms and a final visual inspection. Our in-house test lab holds a wide range of current and legacy switches from major brands, so interoperability is proven on the actual equipment your network uses rather than assumed from paper specifications.
Packaging Options
Default packaging is simple and protective: sealed bag, blister tray, export carton. For OEM customers we also offer white-label packing, custom printed boxes and per-unit labeling with your own part numbers, so the goods can go straight into your sales channel.
Customization Service
Because we are the factory, customization is straightforward: non-standard lengths, different jacket materials, specific polarity or breakout wiring, and compatibility programming for particular switch brands are all routine work for us. Small trial orders are accepted so you can verify quality before scaling up.
How We Ship
Most orders travel by international express and arrive within days; palletized freight by air or sea is used for volume orders. If you prefer, we ship on your DHL, UPS or FedEx account, or deliver to your appointed agent in China for onward consolidation.
