QSFPDD-400G-FR4-SM optical transceiver module

400GBASE FR4 QSFP DD Transceiver Module (1310nm, 2km, MPO-APC, duplex LC connector, SMF)

The QSFP-DD-FR4-400G Optical Transceiver is designed for optical communication applications within data centers, with a range of up to 2km. It can convert 8 channels of 50Gb/s (PAM4) electrical input into 4 channels of CWDM (Coarse Wavelength Division Multiplexing) optical signals. These signals are then efficiently multiplexed into a single 400Gb/s optical transmission channel, which ensures high throughput and reduced latency. The QSFP-DD-FR4 Optical Transceiver meets the industry standards set by IEEE802.3cu-2021, 400G-FR4 Technical Spec D2p0, and CEI-56G-VSR-PAM4.
On the receiving end, the optical module can de-multiplex a 400Gb/s optical input back into 4 distinct CWDM optical channels, which are then converted back into 8 channels of 50Gb/s (PAM4) electrical output. This bi-directional functionality enhances system efficiency and also improves the reliability of data transmission over long distances.

    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.
