400G QSFP56-DD DR4 is designed for use in 400 Gigabit Ethernet links on up to 500m of single mode fiber.

400G QSFP56-DD DR4 Product Overview

The module operates on 1310nm wavelength, and supports 400GE links and up to four 100GE breakout link lengths of up to 500m. The module has four pairs of SMF with an MPO-12 connector. It is compliant to the IEEE 802.3bs protocol and 400GAUI-8/CEI-56G-VSR-PAM4 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 QSFP28 100G-DR, 100G-FR, and 100G-LR. FEC is performed on the host platform.
