Generic 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 LC 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 LC connectors, while each connector can connect to a physically separate 400G FR4 module via an LC OS2 duplex single-mode fiber. This enables 800G to 2x 400G breakout links without the need for using breakout fiber optic cables.

Transceivers type GE-QSFP-DD-800G-2FR4 | 2km | Dual Duplex LC/UPC
Installed these Cisco-compatible 800G 2FR4 modules between two core AI switches and they've been running stable under heavy traffic. The breakout to 2×400G worked exactly as expected, and the CS connectors made cabling much cleaner in a dense rack. DDM readings have been consistent, and compatibility with our Cisco hardware was seamless. Great value compared to OEM optics.
