40G to 400G modules powering data center spine-leaf fabrics and hyperscale backbone connections. MSA-compliant and pre-coded for Cisco Nexus, Arista, Juniper QFX/MX, Huawei CE, and Dell platforms. High-speed QSFP+, QSFP28, and QSFP-DD optical transceivers for 40G. The QSFP-DD OLS is a pluggable open line system solution that can be directly hosted on a Cisco router. 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. QSFP-DD is a new module and cage/connector system similar to current QSFP, but with an additional row of contacts providing for an eight lane electrical interface. With its compact form factor, backward. This article will introduce the next generation optical module in detail, QSFP-DD, also known as quad small factor pluggable, and this article will also introduce the difference between QSFP-DD optical module and other 400G form factor modules. The QSFP-DD is the smallest 400G form factor optical.
