QSFP-DD Product Family

QSFP-DD Product Family

Acacia’s 400G Quad Small Form-factor Pluggable Double Density (QSFP-DD) product family incorporates Acacia’s 3D Siliconization, which leverages the maturity of our silicon photonics technology and our vertical integration, and is designed to enable network operators to address increasing bandwidth demand through a simplified network architecture, reducing both capital and operational expenditures. The 400G QSFP-DD product family is based on our Greylock 7nm DSP, our 3rd generation of coherent DSP supporting low-power pluggable modules, and our silicon photonic integrated circuit (PIC) for an optimized co-packaged design.

The QSFP-DD module is a pluggable solution that fits into high-density switch and router client ports for optical interconnect links. A key application of this form-factor is high-capacity coherent optical transmission over data center interconnect (DCI) edge networks, as well as service provider network applications.

Acacia’s QSFP-DD, and similar OSFP form factor, pluggable solutions leverage its 3D Siliconization technology, which utilizes volume electronics manufacturing processes, designed to be highly scalable and reliable.
