Arista Compatible 2x 400G FR4 QSFP-DD 800G transceiver module supports a max data rate of 850Gbps. It enables the fiber link of 2km over single-mode fiber (SMF) with dual duplex CS connectors. The 800 Gigabit Ethernet signal is carried over 4 wavelengths at 1271nm, 1291nm, 1311nm, and 1331nm. QSFPTEK manufactured 2x 400GBASE FR4 QSFP-DD complies with IEEE 802.3cu-2021, IEEE P802.3ck D3.0, QSFP-DD MSA HW Rev 6.01, 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 FR4 QSFP-DD achieves 800 Gigabit Ethernet through 8x 106.25 PAM4 Retimed 2x400GAUI-4 C2M electrical interface. The 800G FR4 QSFP-DD is widely used for gigabit Ethernet, data centers, and 800G to 2x 400G applications.
Take a look at our test program to get the reliable and high-performance optical transceivers.

Scenario 1: 800G to 800G Direct Connectivity
Scenario 2: 800G to 2x 400GE Connectivity
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.
The QSFP-DD-800G-2FR4 module is designed with dual duplex CS connectors, while each connector can connect to a physically separate 400G FR4 module via a CS to LC OS2 duplex single-mode fiber. This enables 800G to 2x 400G breakout links without the need for using breakout fiber optic cables.

The entire upgrade process was smoother than expected, with no compatibility alarms on the switch side, making it a typical example of a "low-interference upgrade."

This module isn't just used by the network team; the storage and compute teams also participated in its verification. A significant advantage was the high consistency of parameters; results from different teams under varying load scenarios showed minimal differences, reducing the cost of disputes. Overall, the implementation efficiency was higher than with previous batches from other brands, and communication was smoother.

I've grabbed modules from QSFPTEK for three straight years now, from 100G all the way up to this 800G 2FR4. They've never let me down. The price-to-performance ratio is just ridiculous. Gonna tell my whole network team about this place.

My Arista 7060X5-64 switch gets along great with this module. Been running for about two months now, and not a single dropout.

I bought this 2FR4 mainly to replace an old link for peace of mind. The packaging was quite neat upon arrival, and the anti-static measures were well done. After installation, it was basically "plug and play," without much hassle. The price is significantly more friendly than the original manufacturer's, and so far, I haven't encountered any problems.
