Description

Dell Compatible QDD-400G-FR4-S delivers a max link length of 2km over single-mode fiber (SMF) with a duplex LC connector.

The 400GBASE-FR4 transceiver is designed with a QSFP-DD form factor, which provides the industry's highest bandwidth of 400 Gigabit Ethernet (400GbE).

The total 400G signal is carried over four CWDM grid optical wavelengths with a data rate of 106.25Gbps (PAM4) per channel.

On the transmitter side, the FR4 converts the 8 lanes of 50G PAM4 electrical signals into 4 channels of CWDM optical signals, then Multiplex them into a single 400G signal.

On the receiver side, the module will demultiplex the 400G input signal into 4 lanes of CWDM optical signals and convert them into 8 channels of 50G PAM4 electrical signal as output. .
