400GBASE FR4 QSFP-DD Transceiver Module (CWDM4, 2km,  Duplex LC connector, SMF)

The QSFP-DD FR4 400G optical transceiver module supports a data transmission distance of up to 2km. It can convert 8 channels of 50Gb/s (PAM4) electrical input into 4x100Gb/s CWDM (Coarse Wavelength Division Multiplexing) optical signals. These signals are then efficiently multiplexed into a single 400Gb/s optical transmission channel. On the receiving end, the module can separate a 400Gb/s optical input back into four distinct CWDM optical channels. These are then changed back into eight 50Gb/s (PAM4) electrical output channels, ensuring high throughput and reduced latency.
400GBASE FR4 optical module complaint with IEEE802.3cu-2021, 400G-FR4 Technical Spec D2p0, and CEI-56G-VSR-PAM4 standards. Its ability to work in both directions makes the system more reliable and efficient for sending data over long distances. The QDD 400G FR4 optical transceiver module works great for business networks that use AI/ML, VoIP, and data centers for cloud computing.

FAQ

What is the meaning of 400G-FR4?
400G: Data transfer speed for 400 Gigabit Ethernet.
FR4: A 400 Gigabit Ethernet system with four data channels and coarse wavelength division multiplexing that follows a multi-source agreement (MSA). It delivers data at various 1310nm wavelengths via a single-mode fiber (SMF).
QSFP-DD-DR4-400G vs QSFP-DD-FR4-400G, what are their main differences?
Two 400 Gigabit Ethernet transceivers with QSFP-DD connections.
There are two main differences. First, A single-wavelength transmitter limits DR4’s SMF reach to 500 meters. CWDM on SMF can increase FR4’s range to 2 km. Second, Multi-channel MPO connectors are commonly utilized with DR4. FR4 frequently uses LC linkages with single-wavelength connections.

Can I connect a cheaper 100G QSFP+ device to a 400G-FR4 QSFP-DD connection?
This is compatibility confusion. These transceivers look like they may be used together; however, they have separate electrical connections, pin layouts, and data transfer rates.
How different are 40G and 400G in real life?
This shows how updating helps in real life. The speed of data transmission has increased ten times from 40 to 400 Gigabit Ethernet. This could speed up data processing, improve application performance, and reduce data center network congestion.
What CWDM wavelength does this transceiver use for?
To ensure network compatibility, the transceiver datasheet will list the four CWDM wavelengths used to transport data channels on one fiber. These wavelengths are frequently 1310nm.
