2-Port Isolated RJ45 Switch Box

A physically isolated, power-free 2-port RJ45 switch box sized 77 x 50 x 20 mm and weighing approximately 50 g. Manufactured from corrosion-resistant, anti-static ABS plastic with passive thermal management. Supports two distinct hardware-level functions: switching between two network inputs to one output, or duplicating one input across two outputs — both implemented via direct copper path routing. Used across UK financial trading floors, university IT labs, and government contractor sites where deterministic Ethernet behaviour, zero attack surface, and regulatory adherence are non-negotiable.
