The 400GBASE-PLR4 Module, MTP/MPO-12 connector, up to 10km over parallel single-mode fiber. It is compliant to IEEE 802.3bs protocol and 400GAUI-8 standards.
The 400 Gigabit Ethernet signal is carried over four parallel lanes by one wavelength per lane. It can be used as 4x100G breakout to QSFP-LR-100G.
Note: The FS P/N is changed from QSFPDD-PLR4-400G to QDD-PLR4-400G, but the product is the same. Only the FS P/N has been changed.
