The 400GBASE-XDR4 Module supports link lengths of up to 2km parallel SMF with MTP/MPO-12 connector. 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-FR-100G.
Note: The FS P/N is changed from QSFPDD-XDR4-400G to QDD-XDR4-400G, but the product is the same. Only the FS P/N has been changed.
