Technical detail

Construction and application notes for OSFP-800G-2xFR4L

Review connector, construction, routing and handling details that apply to the selected family and exact SKU.

Interface and construction

OSFP-800G-2xFR4L transceiver is engineered for long-reach 6km transmission, purpose-built for NVIDIA Spectrum-XGS Ethernet technology. It achieves low-latency, high-bandwidth, high-speed interconnection, unifying distributed data centers into AI super-factories.

Application and routing

Fiber link loss must remain within the module’s link budget. Excessive loss or fiber end-face contamination can cause failures even at 6km. To ensure reliable performance, conduct OTDR testing for link budget validation, and use G.652D or better fiber at 800G to control dispersion and maintain signal integrity with low BER.
