Home / 1 6T optical module QSFP-DD for IDC data centers
The QSFP-DD1600 will leverage 200-Gbps serial PAM4 SerDes technology over the module's standard eight lanes and maintain backwards compatibility with QSFP and previous QSFP-DD modules and cables. 6T optical modules are, the major module types involved, and the application scenarios driving adoption. Cisco offers a range of GBIC, SFP, XFP, SFP+, CXP, CFP, Cisco CPAK, and QSFP+ pluggable modules. 6T quantum-safe encryption solution on the Waveserver platform was designed with this in mind, supporting QKD system interworking and NIST-certified PQC algorithms. Quad Small Form-factor Pluggable Double Density (QSFP-DD) solution that fits into high-density switch and router client ports for optical interconnect links Powered by Greylock and Delphi DSP ASICs, and silicon photonic integrated circuits (PICs) for an optimized co-packaged design with 3D. Finally, it presents a Total Cost of Ownership (TCO) framework to help you reframe optics from a simple consumable into a strategic infrastructure asset.
These small, modular optical interface transceivers offer a convenient and cost-effective solution for an array of applications in the data center, campus, metropolitan-area access and ring network, storage
