What is the difference between OSFP-800G-2xSR4H and OSFP-800G-2DR4LH?

OSFP-800G-2xSR4H has a transmission distance of 100m and is usually used for 800G OSFP port switches. It can be connected to the opposite end of an 800G OSFP port switch or a 400G/200G OSFP ConnectX-7 port NIC to meet branching applications such as one-to-two or one-to-four connections. OSFP-800G-2DR4LH has a transmission distance of 500m and is typically used for interconnecting two 800G OSFP port switches.

Can this module be compatible with the NVIDIA QM9700 switch, and can you provide the corresponding test report?

Our product is perfectly compatible with NVIDIA QM9700/9790 devices. It undergoes 100% testing and inspection before shipment, and we can provide the corresponding test documentation.

Description

NVIDIA/Mellanox® MMS4X00-NM Compatible 800G 2xDR4/DR8 InfiniBand NDR Optical Transceiver Module(Twin-port OSFP, 1310nm, 500m, Two MPO-12/APC, DOM, for SMF, Finned Top)

NADDOD OSFP-800G-2DR4LH Optical Transceiver Module is an InfiniBand and Ethernet 800Gb/s 2x400Gb/s Twin-port OSFP, 2xDR4/DR8 single mode, parallel, 8-channel transceiver using two, 4-channel MPO-12/APC optical connectors at 400Gb /s each. The parallel single mode, data center reach 8-channel (2xDR4/DR8) design uses 100G-PAM4 modulation and has a maximum fiberreach of 500-meters using 8 single mode fibers. The Twin-port 2xDR4/DR8 transceiver is a key innovation with two internal transceiver engines enabling 64-ports of 400Gb/s in a 32-OSFP cage. The main application for OSFP-800G-2DR4LH is linking two switches together with up to 500 meters.

Product Highlights

800G DR8 Empowers AI Data Center Architecture Upgrade

NADDOD 800G DR8 transceivers are embedded with Broadcom DSP, which has a maximum fiber reach of 500 meters and delivers reliable data transmission.

Driving Powerful Performance on HPC Workloads at Any Scale

Different Heat Sink Designs Upgrade the Level of Performance

Mastering the differences between flat top and finned top, ensuring high performance and stable data transmission.

Finned Top modules feature a top design equipped with heat dissipation fins. The integrated top heatsink enhances cooling efficiency when handling massive data. 800G OSFP optical modules integrated in a heat sink are applicable for Quantum-2 InfiniBand switches and Spectrum-4 Ethernet switches.

Flat Top module's height is 9.5 mm without heat sinks, relying on the heatsinks on the NIC ports to assist the module in cooling, which fits into compact or constrained spaces without interference. 400G OSFP form factor optical modules are used in CX7 HCA.

Questions & Answers

Ask a Question

Can I use only one port for the 800G Twin-Port NDR 2xDR4 optical module?

Yes, if only one of the ports is used, the rate is 400G.

Can 400G OSFP modules be used for 800G OSFP ports?

Yes, 800G OSFP ports are backward compatible with 400G OSFP as long as the physical form factor is compatible.

What are the heat dissipation methods of the NDR module?

One is with "Finned Top" and the other is "Flat Top"; Generally speaking, the "Flat Top" module is mainly used on the NIC side, because the thickness of the NIC is limited. The "Finned Top" module has a module top design with heat dissipation fins, which can increase heat dissipation capacity and improve module performance and reliability in high-temperature environments. It is usually used in Quantum-2 and Spectrum-4 air-cooled switches.

The 100m 800G 2DR4 distance we originally purchased is no longer sufficient for our needs. This product is fantastic, and at least we don’t need to replace the MTP cables, which will save us some budget.
