Product overview

The 400G QSFP-DD module (400GBASE Quad Small Form-Factor Pluggable Double Density) is a new generation of 400G transceiver module based on the QSFP-DD form factor. It is a high-density, high-speed pluggable module with an additional row of contacts. It can provide eight channels of electrical interfaces, and the QSFP-DD module series provide the industry's highest bandwidth density.

Features and benefits of 400G QSFP-DD Modules

1. Support hot swap

Input/output devices plugged into 400G Ethernet Cisco QSFP ports

2. Interoperability

Interoperable with other IEEE standard 400GBASE interfaces when applicable

3. Cisco platform certification

Qualified and tested on QSFP-DD 400G port and obtained Cisco platform certification

4. Comply with IEEE 802.3bs

It is compliant to IEEE 802.3bs protocol and 400GAUI-8/CEI-56G-VSR-PAM4 standard.

5. Comply with QSFP-DD MSA standard

The collaboration of MSA will make the implementation and operation of the QSFP-DD pluggable interface in network equipment faster

6. Ultrahigh speed

PAM4 modulation that supports speeds up to 400G runs at a speed of 50 Gbps.

7. Backward compatibility

Backward compatible with low-speed QSFP (QSFP+ and QSFP28) pluggable modules and cables, designed for high-speed optical network applications.

Application and market of 400G QSFP DD

Guanglian’s 400G QSFP-DD product portfolio provides customers with a variety of ultra-high-density transceiver modules and the flexibility of 400 Gigabit Ethernet connection options. 400G is one of the highest data rates in the Ethernet world, providing critical aggregation and high bandwidth Interconnect applications provide improved functions. Therefore, 400G QSFP-DD is currently the most widely used fiber optic transceiversmodules in this series. The main applications are 400G Ethernet, ultra-large-scale data centers, high-performance computing networks, cloud networks, enterprise core and Distribution layer, Internet exchange, managed services, wireless infrastructure core, service provider and operator core network, and video distribution infrastructure.
