Cisco QDD-400G-DR4-S Compatible 400G DR4 QSFP-DD PAM4 1310nm 500m DOM MTP/MPO-12 SMF Optical Transceiver Module
QSFP-DD 400GBASE-DR4 silicon photonics transceiver is based on a new state-of-the-art silicon photonics (SiPh) platform. It uses SiPh chips that integrate a number of active and passive optoelectronic components, 3D packaging technology and industry-leading 7nm DSP chips. It is a cost-effective and lower power consumption solution for 400GBASE data center.
The 400GBASE-DR4 silicon photonics module supports link lengths of up to 500m SMF with MTP/MPO-12 connector. It is compliant with QSFP-DD MSA, 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 QSFP28-DR-100G.
