Specifications

Cisco QDD-400G-FR4-S Compatible 400GBase-FR4 QSFP-DD Transceiver (SMF, 1310nm, 2km, LC, DDM, 0 to 70C)

 

Cisco 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.

 

The QSFP-DD 400G modules are compliant with IEEE 802.3bs for 400GBASE-FR4 specification and 100G Lambda MSA, and 400GAUI-8/CEI-56G-VSR-PAM4 standards. This 400G QSFP-DD FR4 module has wide adoption in data center interconnect (DCI), 400G Ethernet, Infiniband interconnects, enterprise networking, etc.

Questions & Answers

more+
  • Does 400GBASE-SR8 support DSP?
    Yes, The 400GBASE-SR8 incorporates DSP (Digital Signal Processing) technology, offering greater flexibility than CDR. DSP allows for tailored configuration adjustments to accommodate diverse application requirements.
  • I want to build a 850m optical link, can I use The 400GBASE-FR4?
    Yes, The 400GBASE-FR4 optical module's maximum transmission distance is 2 km, so it can be used for an 850m connection.
  • What type of optical cable should be used with 400G-SR8?
    The 400G-SR8 optical module employs a single-row, angled (APC) MTP16 connector to establish a connection with parallel multi-mode fiber, facilitating the linkage of 8 fiber pairs. We recommend utilizing the QSFPTEK MTP-16 APC OM4 Cable for optimal performance.
