NVIDIA/Mellanox MMS4A00-XM/MMS4C10 (980-9IAH0-00XM00/980-9IAU0-00XM00) compatible 1.6T OSFP224 DR8 Twin-port 2x 800G DR4 transceiver module supports a max data rate of 1600 Gbps. It enables the fiber link of 500m over single-mode fiber (SMF) with dual MPO-12 APC connectors. QSFPTEK manufactured 1.6T 2x DR4 OSFP complies with IEEE802.3dj D1p3:1.6TBASE-DR8 optical interface, IEEE802.3dj D1p3:1.6TAUI-8 C2M electrical interface, OSFP MSA Specification Rev 5.1 RHS type 2, CMIS Rev 5.3 and EU Directive 2011/65/EU (RoHS compliant).
DDM (digital diagnostics monitoring) function is supported on the 1.6T fiber optic transceiver to achieve real-time operating parameters monitoring. With the Pulse-amplitude Modulation (PAM4) modulation, the Datacenter Reach 4-channel (DR4) OSFP adopts 8-channels of 200G-PAM4 electrical modulation and two ports of 4-channel 200G-PAM4 optical Parallel modulation.
The 1.6T DR8 Silicon Photonics OSFP supports InfiniBand XDR end-to-end systems. Designed for supercomputing and HPC, this 1.6T OSFP transceiver is widely used for linking two switches up to 500 meters or to connect the 1.6T end to two breakout 800G switches or adpter cards for compute servers or storage infrastructure. Besides, OSFP-RHS with flat-top design is used in Quantum-3 Quantum-X800 liquid-cooled switches.
Take a look at our test program to get the reliable and high-performance optical transceivers.

Scenario 1: 1.6T XDR Switch to 1.6T XDR Switch Direct Connectivity:
Scenario 2: 1.6T XDR Switch to 2x 800G NIC Breakout Connectivity:
This 1.6T-OSFP-2DR4 is a hot-swappable twin-port OSFP form-factor with dual MPO-12/APC connectors. This design enables it to directly link to another twin-port optical module for 1.6T to 1.6T connectivity. Each of the two MPO-12/APC connectors can also connect to an independently single-port MPO-12/APC transceiver via a standard MTP/MPO-12 APC to MTP/MPO-12 APC OS2 SMF for 1.6T to 2x 800G breakout connectivity, without needing breakout cables.

Was hunting for these liquid-cooled MMS4A00 modules for a project. QSFPTEK had the best price by far. Checkout was super fast and shipping was surprisingly quick. I’ll be back for more.

We bought a couple of these 1.6T modules mainly to prepare for the next phase of our AI cluster expansion. They’re definitely not cheap products in general, but QSFPTEK made the upgrade path much easier to justify.

Good quality, works exactly as expected on the liquid‑cooled switches: no complaints about the modules themselves.

We've been running these 1.6T DR8 modules in a liquid-cooled setup and they've been very stable under sustained AI traffic. Installation was straightforward, and link performance has stayed consistent with no issues so far.

Not much difference from the OEM version, but at a much better price. The most economical choice. I'll be buying more.

We were mainly concerned about heat because the switches are running in a high-density air-cooled environment, but the RHS cooling structure actually made a noticeable difference. Running dual 800G breakout links to separate compute nodes worked smoothly, and we didn't see abnormal BER or link flapping during burn-in tests.
