Network architects choose the 800G OSFP 2x FR4 Optical Transceiver for InfiniBand NDR fabrics, GPU clusters and AI training networks: it runs 850Gbps (8x 106.25Gbps) over SMF and reaches 2km. With its Dual Duplex LC/UPC optical interface, the module works directly with the SMF infrastructure already installed in most facilities. For networks standardized on NVIDIA/Mellanox InfiniBand hardware, it is a drop-in equivalent of the MMS4X50-NM. The link runs 8x100G-PAM4 modulation, which keeps it aligned with current 800G switch silicon.

On the compatibility side, this unit is the practical equivalent of the NVIDIA/Mellanox InfiniBand part MMS4X50-NM and works in NVIDIA/Mellanox InfiniBand systems out of the box. Standards compliance covers OSFP MSA HW Rev 4.1, CMIS Rev 5.0, IEEE 802.3cu-2021, IEEE P802.3ck D2.2.

To order, quote OSFP-2FR4-800G 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.

Our product line has grown with the industry for three decades, from GBIC-era modules to today's 800G and 1.6T interconnects. If the exact configuration you need is not listed, we can usually build it: custom lengths, mixed connector breakouts, OEM branding and project-specific firmware coding are all supported.

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.

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.

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.
