Applications
In InfiniBand HDR fabrics, HPC clusters and AI computing networks, the 200G QSFP56 SR4 Optical Transceiver delivers 200Gbps transmission over MMF with a reach of 70m@OM3/100m@OM4. The MPO-12/UPC interface and 850nm optics match the standard cabling plant used in modern data halls, so existing trunks can be reused. For networks standardized on NVIDIA/Mellanox Ethernet hardware, it is a drop-in equivalent of the MMA1T00-VS. The link runs 4x50G-PAM4 modulation, which keeps it aligned with current 200G switch silicon.
Standards and Compatibility
Compliance: IEEE 802.3bs, QSFP56 MSA, SFF-8665, SFF-8636. For projects standardized on NVIDIA/Mellanox Ethernet hardware, this product replaces the MMA1T00-VS 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
Our part number for this module is QSFP-SR4-200G. When ordering, just let us know the quantity and whether you need the compatibility coding for a particular switch brand; labeling and packaging can also follow your channel requirements.
Logistics
Our warehouse keeps fast-moving transceivers and cables ready for same-week dispatch. Courier, air freight and sea freight options are all available depending on your budget and schedule, and we consolidate multiple items into one shipment whenever it saves you cost.
Quality and Testing
Every unit we ship is tested in our own test bed on mainstream switch and transport platforms before packing. Our test center has been fully upgraded, which sets us apart from other third party product providers: 10G, 40G, 100G, 200G and 400G transceivers and direct attach cables are verified on the latest top brand equipment, including selected original switches that can hardly be found elsewhere.
How We Pack
Transceivers and cables are individually protected against static and dust, then consolidated into sturdy cartons suitable for international courier shipment. For larger orders we shrink-wrap and strap cartons onto pallets. Tell us your warehouse or retail requirements and we will pack accordingly.
Factory Custom Capability
Working directly with the manufacturer means no middleman limits. We support OEM and ODM projects, custom cable assemblies, alternative packaging and compatibility coding for major equipment vendors, with engineering support from the same team that designs our standard products.
