About the TCP Ethernet Port black outline icon
An RJ45 ethernet port silhouette with its notched keyed tab fills a square frame, the letters TCP set across the middle and three stacked signal arcs radiating above them. It communicates network protocols, transport-layer connections, ports and data transmission. Suited to networking dashboards, hosting and firewall configuration panels, API and protocol documentation, IT infrastructure diagrams, and telecom or cybersecurity presentations.
The outer square border keeps the mark balanced while the port shape and lettering stack vertically inside it, with the arcs adding a connectivity cue at the top. Letterforms are the smallest element here. It sits alongside UDP, HTTP, IP and router icons in the protocol set. Use at 48 px or larger so the TCP label stays readable.
This is the black outline version of the tcp ethernet port icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
It downloads free as an SVG vector or transparent PNG in seven sizes, and the free online editor lets you recolor it, apply gold, silver, neon and gradient styles, add animation, or convert it to EPS, PDF and DXF.
