I was looking at a Raspberry Pi board and was struck with how large the ethernet connector is in comparison to the board as a whole. It strikes me: ethernet connectors haven't changed that I'm aware in pretty much 25 years. Every other cable has changed several times in that time frame. I imaging that if anybody cared, ethernet cables could be many times smaller. Looking at wiring closets,etc, it seems like it might be a big win for density too. So why, oh why, nanog the omniscient do we still use rj45's? Mike
The primary reason that pops to mind is backwards compatibility... Ubiquitous availablity of the parts for RJ45 connectors (end connectors, wall plates, panels, etc.) also means that it is more economical to continue using the well established connector. A new connector would drive up costs initially, whereas continuing to use RJ45 is cheap and already works.
