| 3 | Generic | 400G OSFP DR4 |
The HYTOPTODEVICE Flat Top OSFP-400G-DR4 is 100% compatible with the following OSFP-RHS (Riding Heat Sink) ports:
ConnectX-7 NICs: * CX713106A-ADOT (Single-port OSFP 400G)
CX713105A-ADOT (Single-port OSFP 400G)
BlueField-3 DPUs: * MBF3R142A-ASBT (400G OSFP DPU)
MBF314A-ASOT (400G OSFP DPU)
Arista 7060X4 Series: While switches usually use "Finned" tops, some high-density Arista configurations in specialized server chassis require Flat Top modules to clear mechanical obstructions.
Intel® E810-CQDA2 (OSFP Variant): Specialized 400G OSFP adapters for data centers.
Certain Edgecore or Delta switches with shallow-depth OSFP cages designed for external heat dissipation.
Spine-Leaf Fabric: Serving as the core interconnect between Spine and Leaf nodes in 400G switch architectures.
400G to 4x100G Breakout: Supports splitting one 400G port into four independent 100G-DR links via MPO-12 breakout cables for flexible multi-rate equipment mixing.
Open Networking & White Box Switches: Fully compatible with switches running SONiC or other open-source NOS, significantly reducing Total Cost of Ownership (TCO).
AI/ML Computing Interconnects: Providing stable, high-speed single-mode connectivity for GPU nodes within a 500-meter range.
