Speed you need, from QSFP to zQSFP
Our complete quad small form factor pluggable, QSFP connector portfolio includes QSFP+, zQSFP, QSFP28 and QSFP56. We provide a large range of simple and customizable design options. Our QSFP portfolio provides a simple upgrade path from 10 Gbps NRZ to 28 Gbps NRZ and 56 Gbps PAM-4 — including four channels of data in one pluggable interface. Each channel is capable of transferring data from 10 to 56 Gbps and supports a total of up to 200 Gbps per port. These interconnects have 3x the density of SFP products. Our QSFP product portfolio includes cages in single, ganged, and stacked configurations with various light pipe, bezel mount, and heat sink options.

Stacked Belly-to-Belly zQSFP+ Cages
-
View Products
Our new stacked belly-to-belly cages address the requirements for higher density switch designs using next-generation 48 and 64 silicon ports, including Open Compute Project (OCP) reference designs. They support a single printed circuit board (PCB) architecture (versus two PCBs) in each line card, saving significant costs.
Thermally Enhanced zQSFP+ Cages
