Applications
In InfiniBand NDR fabrics, GPU clusters and AI training networks, the 800G OSFP SR8 Optical Transceiver delivers 850Gbps (8x 106.25Gbps) transmission over MMF with a reach of 30m@OM3/50m@OM4. The Dual MTP/MPO-12 APC interface and 850nm optics match the standard cabling plant used in modern data halls, so existing trunks can be reused. Compatibility with NVIDIA/Mellanox InfiniBand systems is verified in our own test lab before shipment, so the unit works out of the box as an equivalent of MMA4Z00-NS. The link runs 8x100G-PAM4 modulation, which keeps it aligned with current 800G switch silicon.
Standards and Compatibility
On the compatibility side, this unit is the practical equivalent of the NVIDIA/Mellanox InfiniBand part MMA4Z00-NS and works in NVIDIA/Mellanox InfiniBand systems out of the box. Standards compliance covers OSFP MSA, CMIS 5.0, IEEE 802.3db, IEEE 802.3ck.
Ordering Information
To order, quote OSFP-SR8-800G together with your quantity. Stock items ship quickly; for OEM orders we support custom labels, retail packing and vendor-specific coding, all handled in our own factory.
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.
Reliability Control
From incoming component inspection to final burn-in, quality is controlled at each step of production. Finished units are verified on real networking equipment in our compatibility lab, and test records are kept per batch so that any field question can be traced back quickly.
Packaging
Each unit is sealed in an anti-static bag, cushioned in a blister tray and boxed in an export-grade carton. Outer cartons carry handling marks and can be palletized for air or sea freight. If your project requires retail boxes, barcodes or your own brand on the label, we can arrange that as well.
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.
