Assmann Electronics DN-81005 1.25Gbps Plug-in module Transceiver

Network downtime can cripple your business, especially when you need an extra Ethernet link but have no free ports on your switch. The Assmann Electronics DN-81005 1.25Gbps Plug-in module Transceiver is a hot-plug SFP copper module that adds a RJ-45 uplink to any compatible switch, letting you expand capacity without interrupting traffic.

Why the Assmann Electronics DN-81005 1.25Gbps Plug-in module Transceiver is the perfect fix for your port shortage

Modern switches often run out of SFP slots, leaving you unable to connect additional wired devices. This forces costly upgrades or network re-architectures. The DN-81005 solves the issue by converting a free SFP slot into a reliable 1000Base-T copper port. Because it follows the MSA standard, it works with the majority of leading switch brands, and its hot-swap design means you can install it while the network stays up. The result is a seamless, cost-effective way to extend your gigabit network.
