800G OSFP SR8 FL Optical Transceiver

The 800G OSFP SR8 FL Optical Transceiver is a Twin-port OSFP RHS/Flat Top optical transceiver delivering 850Gbps (8x 106.25Gbps) over MMF. Operating at 850nm with a Dual MTP/MPO-12 APC interface, it reaches 30m@OM3/50m@OM4&OM5 and is compliant with OSFP MSA, IEEE 802.3-2022, IEEE 802.3ck-2022, CMIS Rev 5.0. Built-in digital diagnostics give real-time access to operating parameters, making the module easy to deploy and maintain in InfiniBand NDR fabrics, GPU clusters and AI training networks.

Applications

The 800G OSFP SR8 FL Optical Transceiver is used in InfiniBand NDR fabrics, GPU clusters and AI training networks, where it provides an 850Gbps (8x 106.25Gbps) link over MMF up to 30m@OM3/50m@OM4&OM5. Digital diagnostics report transmit power, receive power and temperature in real time, which simplifies commissioning and ongoing maintenance. It is interoperable with NVIDIA/Mellanox InfiniBand platforms and replaces the NVIDIA/Mellanox InfiniBand part MMA4Z00-NS-FLT directly. 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-FLT and works in NVIDIA/Mellanox InfiniBand systems out of the box. Standards compliance covers OSFP MSA, IEEE 802.3-2022, IEEE 802.3ck-2022, CMIS Rev 5.0.

Ordering Information

Order this product as OSFP-SR8-800G-FL. 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.

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 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.

Built to Your Spec

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.

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.
