Cisco QSFP-DD800 Transceiver Modules Data Sheet

The Cisco family of QSFP-DD800 modules leverages the cornerstone of high-speed, high-density pluggable form factors, QSFP. The QSFP-DD800 provides the industry’s highest bandwidth density of any transceiver module and backward compatibility to lower-speed QSFP pluggable modules and cables.

Product overview

The Cisco QSFP-DD800 modules introduce 800G and 2x400GBASE Quad Small Form-Factor Pluggable Double-Density (QSFP-DD) modules, offering customers super-high-density pluggable transceivers along with the flexibility of 400 Gigabit Ethernet and 100 Gigabit Ethernet connectivity options for data centers, high-performance computing networks, enterprise core and distribution layers, and service provider applications.

The QSFP-DD800 modules are Cisco’s generation of 800G and 2x400G pluggable transceiver modules based on a QSFP-DD form factor providing 800G connectivity along with breakout options of 2x 400G, 4x 200G and 8x 100G.

Note: Except for QDD-8X100G-FR, only connections with patch cords with PC or Ultra-Physical Contact (UPC) connectors are supported. QDD- 8X100G-FR requires patch cords with Angled Physical Contact (APC) MPO connectors. All cables and cable assemblies used must be compliant with the standards specified in the standards section of this data sheet.

Cisco QSFP-DD800 transceiver prominent features and differentiators

QDD-800G-VR8

QDD-800G-VR8

The Cisco QDD-800G-VR8 module (Figure 1) supports 800GBASE-VR8 as well as 2x 400GBASE-VR4, 4x 200GBASE-VR2, and 8x 100GBASE-VR1 breakouts for links up to 50m(OM4/5) in reach. The module has eight pairs of multi-mode fiber with dual MPO-12 APC connectors. It is compliant with IEEE 802.3 800GBASE-VR8 and QSFP-DD800 MSA module requirements. Optical signals are carried over eight pairs of parallel lanes, with one wavelength per lane. The optical interface can interoperate with any IEEE-compliant module regardless of the form factor. Forward Error Correction (FEC) is performed on the host platform. The QDD-800G-VR8 module is field firmware upgradeable, complying with CMIS 5.3 firmware upgradability process.

QDD-8X100G-FR

QDD-8X100G-FR

The Cisco QDD-8X100G-FR module (Figure 2) supports 800G and a variety of breakout options for link lengths of up to 2 km. The module has eight pairs of single-mode fiber with MPO-12 APC connectors. It is compliant to the IEEE 800GBASE-DR8-2, 400GBASE-DR4-2 and 100GBASE- FR1. Optical signals are carried over eight pairs of parallel lanes by one wavelength per lane. The QDD-8X100G-FR modules can be used to interface to other 800G compliant modules regardless of the form factor. It can also be used as 8x100G breakout to QSFP28 100G-DR (up to 500 m), 100G-FR (up to 2 km), and 100G-LR (up to 2 km). It may also be used as two independent 400GBASE-DR4 transceivers in a single port. FEC is performed on the host platform.

QDD-2X400G-FR4

QDD-2X400G-FR4

The Cisco QDD-2X400G-FR4 module (Figure 3) supports link lengths of up to 2 km SMF with two duplex LC connectors. It is compliant to IEEE 802.3cu for 400GBASE-FR4 requirements and 100G Lambda MSA group. 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.
