I was looking at a Raspberry Pi board and was struck with how large the 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?


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.
