Boasting a twin-port OSFP finned-top form factor, it is engineered specifically for deployment in air-cooled Ethernet switches. 800G optical transceiver features low latency, low power consumption, and high reliability, meeting diverse connectivity needs in spine-leaf network architectures. 800G optical transceiver is an ideal connectivity solution for high performance computing (HPC), artificial intelligence (AI), and cloud data center applications.
Below solution is based on an 800Gbps speed, paired with OSFP SR8 800G fiber transceiver, and connected via MTP|MPO cable. It is compatible with devices such as NVIDIA Spectrum-4 switches, easily achieving high speed data interoperability at the 800G level.
Meanwhile, OSFP SR8 800G fiber optic transceiver can be used for flexible interoperability between 800G and 400G Ethernet. As shown in the picture below, using the OSFP SR8 800G fiber optic transceiver and connecting two 400G optical transceiver via MTP|MPO fiber cable, data transmission from 400G to 800G can be achieved. This is a highly adaptable high speed connection solution for network upgrades and application such as data centers.
Finned Top 800G transceiver tailored for Ethernet air-cooled switches, features integrated finned heat sinks for efficient passive cooling (reducing junction temperature by 5-10°C vs flat-top modules). Fully tested for mainstream switches (e.g., NVIDIA Spectrum series) with plug and play compatibility, 800G transceiver supports 800G PAM4 transmission, suits data centers and AI clusters, reduces room energy consumption, and solves core heat dissipation/compatibility pain points for efficient, stable high speed networks.
