NVIDIA/Mellanox MMS4X00-NS-T (980-9I30H-F4NM00) Compatible 800GBASE-DR8 (2x400G DR4) OSFP finned-top transceiver module supports a max data rate of 850Gbps. It enables the fiber link of 100m over single-mode fiber (SMF) with dual MPO-12 APC connectors. QSFPTEK manufactured 800GBASE-DR8 (2x 400GBASE DR4) OSFP complies with IEEE 802.3cu-2021 8x100GBASE-DR optical interface, IEEE P802.3ck D3.0 8x100GAUI-1 C2M electrical interface, OSFP MSA HW Rev 4.1, CMIS Rev 5.0. DDM (digital diagnostics monitoring) function is supported on the 800G fiber optic transceiver to achieve real-time operating parameters monitoring. Adopting the Pulse-amplitude Modulation (PAM4) modulation, the 2DR4 OSFP achieves 800 Gigabit Ethernet through 8x 106.25 PAM4 Retimed 2x400GAUI-4 C2M electrical interface.
The 800G DR8 is an Ethernet (EN) 800Gb/s 2x400Gb/s Twin-port OSFP. The OSFP-IHS with finned top design is used in Spectrum-4 Ethernet air-cooled switches to switches, ConnectX-7 and BlueField-3 DPUs. QSFPTEK NVIDIA Ethernet compatible optics are 100% tested in NVIDIA Ethernet host devices, ideal for Ethernet end-to-end systems.

Undergoes Comprehensive Performance Testing to Guarantee Optimal Reliability
The QSFPTEK test center conducts complete testing procedures with advanced professional test equipment, including BER test, eye diagram test, Optical Spectrum test, jitter test, etc. Each module has been stringently tested by world-class test devices from Keysight and Anritsu to guarantee flawless operation and optimal reliability.
Select a Proper Heat Dissipation Design for Your Needs

| Closed Finned Top 800G OSFP optics with Integrated Heat Sink (IHS) design are used for both Quantum-2 InfiniBand or Spectrum-4 Ethernet air-cooled and liquid-cooled systems. | Flat top 800G OSFP optics with Riding Heat Sink (RHS) design are used in Liquid-cooled and DGX H100 Cedar7 Systems. |
This 800GBASE-DR8 OSFP module utilizes Broadcom's top-tier PAM-4 DSP chip combines ultra-low bit error rate with the industry's lowest power consumption. It uses advanced equalization technology to compensate for optical impairments and integrates FEC functions to ensure link reliability, providing core support for high-speed data centers and AI clusters.
The 800G OSFP 2DR4 module is designed with dual MPO-12/APC connectors, while each connector can connect to a physically separate 400G DR4 OSFP/QSFP-DD/QSFP112 module via an MTP/MPO-12 APC OS2 SMF. This enables 800G to 2x 400G breakout links without the need for using breakout fiber optic cables.

Utilize 8x electrial lanes and 8x optical lanes modulated at 100G PAM-4 per lane. On the output side, it convert 8x 106.25Gb/s electrical signal to 8x 106.25Gb/s optical signals. On the receiver side, it convert 8x 100Gb/s optical signal to 8x 100Gb/s electrical signals.

Transceivers type MMS4X00-NS-T OSFP 2DR4 | 100m | Dual MPO-12/APC | IHS/Finned Top

We bought this module not for a new project, but to replace an old, faulty link. We initially thought we'd need to spend time troubleshooting compatibility after the replacement, but the module arrived, was installed directly, and quickly restored normal operation. The whole process was much smoother than expected. From this perspective, the biggest advantage of this product isn't its specifications, but its ability to quickly resolve problems in critical situations.

Traffic has been consistently heavy, but the link status has remained clean, with no occasional disconnections or abnormal retraining issues. One notable improvement is that temperature control performed better than expected, especially under full rack load, without significant performance fluctuations.

We've been running these for a while now between storage and compute systems over single-mode fiber. One thing I've noticed is that they just quietly do their job. No random alarms, no intermittent link drops, and no unexpected support tickets from the operations team.

The deployment was, no firmware drama, no compatibility surprises, no random alarms afterward. The heatsink version also feels well built in hand compared to some lightweight optics we’ve tried before. Shipping was faster than expected too, arrived in about 4 days to our site.

This order was due to a tight project schedule, and I was quite worried about the shipping time, but it arrived in 4 days, much faster than expected. The outer box wasn't damaged. The module worked normally after installation, and I didn't encounter any shipping-related problems, which was a big plus.
