Portower E681 Series Switch — Next-Gen 100GE Data Center Networking

Portower is proud to introduce the E681 Series — a carrier-grade Layer 3 Ethernet switch engineered for the demands of modern data centers, enterprise networks, and high-performance computing environments.

Product Overview

The E681 48X8C is a 1U fixed-form-factor switch delivering 48 × 10GE SFP+ downlink ports and 8 × 100GE QSFP28 uplink ports. Powered by the CTC8180 chip, it achieves a total switching capacity of 3.2 Tbps and a forwarding rate of 2,380 Mpps in cut-through mode, making it one of the highest-performance switches in its class.

Technical Specifications
