The Cisco® family of QSFP-DD modules provide the industry’s highest bandwidth density while leveraging the backward compatibility to lower-speed QSFP pluggable modules and cables.

Product overview

The Cisco 400GBASE Quad Small Form-Factor Pluggable Double Density (QSFP-DD) portfolio offers customers a wide variety of super high-density transceiver modules and the flexibility of 400 Gigabit Ethernet connectivity options for data center, high-performance computing networks, enterprise core and distribution layers, and service provider applications. The QSFP-DD modules are our new generation of 400G transceiver modules based on a QSFP-DD form factor.

Cisco 400G QSFP-DD transceiver prominent features and differentiators

Cisco QDD-400-CUxM

QDD-400-CUxM

Figure 1.               

QDD-400-CUxM

The Cisco 400G QDD-400-CUxM module (Figure 1) primarily enables high-bandwidth 400G links and supports 400G Ethernet rate. It provides a QSFP-DD-to-QSFP-DD copper direct-attach solution. QDD-400-CuxM cables are suitable for very short links and offer a cost-effective way to establish a 400-Gigabit link between QSFP-400G ports of Cisco switches/routers within racks and across adjacent racks. Cisco currently offers passive copper cables in lengths of x=1, 2, 2.5, and 3 meters.

QDD-400G-DR4-S

QDD-400G-DR4-S

Figure 2.               

QDD-400G-DR4-S

The Cisco QDD-400G-DR4-S Module (Figure 2) supports link lengths of up to 500m parallel SMF with MPO-12 connector. It is compliant to 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-FR-S. FEC is performed on the host platform.

QDD-400G-FR4-S

QDD-400G-FR4-S

Figure 3.               

QDD-400G-FR4-S

The Cisco QDD-400G-FR4-S Module (Figure 3) supports link lengths of up to 2km SMF with duplex LC connector. It is compliant to IEEE 802.3bs, 400GBASE-FR4 Spec of 100G Lambda MSA group, and 400GAUI-8/CEI-56G-VSR-PAM4 standards. The 400 Gigabit Ethernet signal is carried over four CWDM grid optical wavelengths. Multiplexing and demultiplexing of the four wavelengths are managed within the device. FEC is performed on the host platform.

QDD-2X100G-SR4-S

QDD-2X100-SR4-S

Figure 4.               

QDD-2X100-SR4-S

The Cisco QDD-2X100-SR4-S Module (Figure 4) supports link lengths of up to 100m on OM4 MMF. The module uses an MPO-24 MMF connector. It is compliant to IEEE 802.3 100GBASE-SR4 requirements. The module provides backward compatibility to two 100GBASE-SR4 transceivers, improving port efficiency to legacy 100G optical interfaces.

QDD-2X100G-CWDM4-S

QDD-2X100-CWDM4-S

Figure 5.               

QDD-2X100-CWDM4-S

The Cisco QDD-2X100-CWDM4-S Module (Figure 5) supports link lengths of up to 2km SMF and uses a dual duplex CS connector. It is compliant to 100G-CWDM4 MSA. The 100 Gigabit Ethernet signal is carried over four CWDM grid optical wavelengths at 25Gb/s each. Multiplexing and demultiplexing of the four wavelengths are managed within the device. FEC is performed on the host platform.
