    I, too, remember this. All the way back in the 1890s someone had calculated CO2 emissions and global warming. Also, the oil industry did in the 1950s, but kept the data for themselves. In both cases, they were right about the CO2 count at the end of the century, about 20 years ago. We’ve blown right past that number since.








  • Passthru lets you push the wires all the way through the plug. With a compatible crimp tool, it will lock in the wires and trim off the excess in one go. This lets you push the jacket as far into the plug as possible, so it has a good, secure grip on the cable when crimped.

    If you don’t have a compatible tool, just a normal rj45 crimper, you can push the wires all the way through, cut the excess as far back as it allows, then carefully pullback until the wires are flush with the end and not sticking out - it’s important they don’t stick out or you could short things in some cases. You also have to be more careful to make sure the wires are correctly at the end of the plug and not too far in or out when you put it in the crimper - it will inevitably over or undershoot with a passthru if you don’t have the right tool.

    Some say the traditional rj45 is better, some say the passthru is better.

    Also, never crimp with the other end plugged into anything.
