    Generic 4x100GBASE-LR QSFP-DD PAM4 1310nm 10Km DOM Transceiver Module (SMF, 1310nm, 10Km, MTP/MPO, DOM)

     

    The QDD-4X100G-LR 400G-PLR4 module is designed to reach 10km distances over single-mode fiber (SMF) for 400 Gigabit Ethernet transmission. The 400 Gigabit Ethernet signal is carried over four parallel lanes by one wavelength per lane. The 4x100GBASE-LR module uses MTP/MPO-12 connector, supporting breakout mode. It can be applied in the 4x100G breakout connectivity of QSFP-DD to QSFP28 100G-LR.

     

    QSFPTEK QDD-4X100G-LR 4x100GBASE-LR QSFP-DD module is compliant with QSFP-DD MSA, 100G Lambda MSA, OIF 56G PAM4, and IEEE 802.3cu for 100GBASE- LR1 and is mainly applied in 400G Ethernet, Data Center and Cloud Networks.
