Ask Slashdot: Is It Time To Shrink the Ethernet Connector? 566

New submitter jimwelch writes: HDMI has shrunk to mini, then micro. USB has shrunk to mini, then micro. The wired Ethernet connector has not changed since 1988!

      A bunch of datacenters are already switching to RJ point 5, because it halves the amount of space taken up by top-of-rack switches and patch panels. There's no need to rewire anything, as they both terminate to the same Cat6 cable, and patch cables are available for RJ.5 to RJ-45.

      See here [te.com].

      I'm really curious as to what sites actually have so much shit in their racks that they need to reclaim 1U by replacing the 2U 96 port ToR switch with a 1U 96 port ToR switch. I guess it might be micro, sub 1U servers, but then I wonder why they don't use backplane ethernet in these racks. Anyway someone clearly thought there was a need, and now there is RJ.5; Also microSFP, apparently, because 96 ports of 10G in 2U is not enough these days... I'm amazed they can make the thermals work to get 96x10G ports into a 1U switch or line card.

      One of the biggest advantage of the rj-45 port is the relative ease of making a connection. Having smaller ports means we will need factory built connectors. And need all wires to be presized for all jobs. Making wiring much more difficult.

      Besides most small tech that cannot handle the RJ-45 sized ports are built fore wireless networking. Which for most used is fast enough.

    • I would be all for it if there was a discernible purpose and it's easy to see a half dozen of them. For instance moving to fiber optic. 10G is 10 years overdue but still stupidly expensive. TOSLINK delivered consumer $0.10/foot fiber optic cabling to the masses 20 years ago. We need to move to 10G at consumer prices and we should upgrade to a consumer priced fiber optic option based on plastic.

            All ethernet devices of the last 10+ years can autonegotiate between straight and cross-over wire configuration. So with wires on the connector organized as tx+ tx- rx- rx+ (4-wire example), a flippable connector would not require any changes in the electronics. And it would get rid of the impedance-killing central pair split in today's standard connector.

      Not just this, but I can go and cut and make a new cat 5/6 cable in a couple minutes. Anything smaller and I'm certainly not running a length of cable out and crimping my own RJ45 heads on. We could probably come up with something to use 'from the wall', as those 'short' runs to a PC or laptop are the smallest of all runs of the cable itself and if you really want to do that you already can with USB (though it requires an adapter and is therefore expensive).

      Any replacement to Cat 5/6 and it's trusty RJ45 connectors needs to be as easy and offer as much bandwidth as the current tech to gain any traction. If it requires premade cables in a variety of lengths I just don't see it gaining any traction in a typical office or business environment. Heck one of the last places I worked for wanted me to make cables for everything because they were to cheap to have a variety of common lengths (7, 10, & 15 foot cables for instance) on hand, when we had a spool of Cat 5e cable for our wall/ceiling wiring needs.

      • What if it is the exact same wire and almost the exact same connector, just one third of the height?

        That could still work and be easy to deal with, though I would prefer to also replace the locking mechanism with something that lets go instead of breaking.

    Any reduction would be at the expense of compatibility with everything which already exists. Modular connectors are reliable, cheap, easy to install, they work.

    One of the reasons, I think, that the RJ-45 connector has lasted so long is it's very easy to field install. A bag of cable ends and a relatively inexpensive crimp tool is all you need, and the wires are easy to insert. Making a connector that's appreciably smaller would make field installation of ends that much more difficult.

    Introduce a new standard and now you'll need new cables (wall jacks to device) or adapters (cables to device) to keep new things interchangeable with existing things. That doesn't simplify anything.

    That's assuming it CAN be made smaller, given the cable is unlikely to change.

    Ethernet is an attempt to use the cheapest cable possible for the longest distance possible for the highest bandwidth possible. That's part why TIA/EIA standards do not specify the cable, they specify the performance characteristics that must be met. This is why it's possible to run Gigbit over some particularly short distances over Category 3, or why it's possible to get 10G out of 6 or 5e for some short distances.

    Changing the connector means that the horizontal cable gets more expensive, the jacks get more expensive, the patch cord material and plugs get more expensive.

    There already has been interest in changing the connector, larger. There was a cable that put four pins on the top to attempt to electrically separate the pairs to reduce crosstalk. It didn't take off, probably because the developer didn't want to license it cheaply enough, ie, free. There were attempts at hermaphroditic cables, but they were larger and had licensing issues.

    My opinion: leave it as is

    My thinking is;
    Most connected items that are portable or IoT already use WiFi now so having a smaller connector wouldn't really be a benefit.

    For the larger systems like desktops and servers there would be little to no benefit from the smaller connector.

    A standard RJ45/8P8C connector/jack is already about as small as you can get it and still be able to see what your doing when you install them.

    Currently the tools and connectors used for CAT X cabling are completely standardized and interchangeable with most of the telephone hardware still out there. Things like the line testers and punch down tools work on both systems so I have less I need to buy and carry when in the field working with mixed systems.

    All the older hardware, the Smart TV's, the server patch panels, the home routers, hubs, etc. use the full size connector. I don't think people would be happy if they bought a new router and had to get all new cables to boot.

  • How about a smaller plug with 4 contacts (RX pair and TX pair). But make it with the same contact pitch as the RJ-45 and include a space to correspond to the RJ-45 pin 3 (unused for Ethernet). Then, make a plastic backshell that snaps onto the new connector, making it as thick and wide as the old RJ-45. So it will plug into older equipment.

    No, leave it as is. For one reason, ethernet cables are often hand made or hand terminated. I've terminated 1000s of cables in my career, various lengths and runs. The current connector, while not perfect, is just about the right size for hand termination without expensive or specialized equipment. My bag always has a crimper and spare connectors in it. I can easily whip up a cable on a moments notice. If you go to a mini or micro connector, more specialized equipment will be involved that may not allow one to hand terminate a cable easily. If we lose that, we lose the versatility of the connector in general.

  • Because it's versatile. With the right tools, it's incredibly easy to terminate and repair in the field. Parts are cheap. And I can crimp any length cable whenever I need it.

    But copper has its limits. To get beyond those limits, pair twists are tighter, cables are getting thicker, pull specs more delicate, and installation more complex. As conductors get thicker and shielding becomes mandatory, backwards compatibility is proving a challenge. We're now at the point where manufacturers like Leviton are

  • The physical size of a connector is related to whether it needs to be handled by human hands, and if so, whether a locking mechanism is part of the connector, which also must be handled by human hands. Beyond that, it's the physical size of the necessary cable that forms the final parameter.

    The Ethernet Connector could be made slightly smaller and satisfy the above, but not by much. There is no need for change when it's for the sake of change. So, the current RJ-45 is perfectly adequate and need not be furt

    The beauty of the RJ-45 standard is that it has low insertion force, a positive engagement report (the click when the cable seats properly), and it is essentially impossible to put in the wrong way. It remains in place without screws, and yet releases easily. The only shortcoming it has is the fragility of the catch mechanism when pulling cables through walls or cable trays, but various manufacturers have come up with a range of boot designs to circumvent that problem. You can recognise the connector port by feel, and know the orientation blindly (ie, around back of the equipment you can't get your head behind to be able to see). Other people might disagree, but in my experience, it's the most reliable connector in common use. Maybe the RJ-11 (standard telephone jack) was, in its heyday, more commonly deployed, but probably not. I have never, ever, not once, found a panel-mounted RJ-11 or RJ-45 that had failed.

    Compare with the micro USB: insertion force is high enough that it's close to the force required to plastically deform the connector when putting it in the wrong way, yet, it can easily fall out under many circumstances. There is no positive feedback on proper seating. The holes for a micro USB are indistinguishable by feel from many other ports (at least to me). There is no retention mechanism other than friction. The connectors are very fragile, and nearly impossible to join to the cable in the field (read: you can't make your own cables). The insertion count lifetime is quite low, and I've worn out quite a few of them myself. It's a poor standard.

    The folks designing the RJ-45 and its sister standards were frelling brilliant. The people designing the more recent stuff ... not so much.

  • Increasingly, people just connect to networks via USB connectors. The fact that there is a little USB-to-Ethernet chip at the other end of the cable hardly matters. With high-speed USB-C connectors, you can run networking, display, and power over the same small connector and cable.

    I'm confused why everyone started talking about servers and datacenters and stuff. Surely if this actually happened, it would be done the same way as mini/micro HDMI & USB: The hubs switches and servers would all keep using the same old 8p8c, and the mini connector would just be used on the other end for the ultrathin laptops and stuff.

    From the question's comparison to a bunch of cables that you can't (easily) terminate yourself, I'm going to assume you buy all your ethernet cables. That's great except when you want to fish cable through walls, and use punchdown jacks in patch panels. Or make one that's a custom length. Or repair a 30m cable with a broken wire 5mm from one end.

    The only thing wrong with RJ45 is the fragility of the locking tab, and plastic overshields do a pretty good job of protecting that.

    You only change based on the need.

    a. HDMI to micro: the need was super slim laptop output, try finding a 1" thick laptop nowadays
    b. USB to micro USB: the need was super slim smart phones, try finding a 0.4" thick smartphone nowadays.
    c. Ethernet: there are plenty of 1U+ blades, desktop computers, and industrial stuff (Ethercat) that are fine using RJ45. There is no need.
    d. RPi could use a smaller ethernet connector but:
                a few 100K pi's vs a million blade servers.... spanning models from 2000 to 2016 (not everyone is Google, Facebook, or Amazon that can replace their 2015 servers asap).
                Designs like the RPi should goto a connect that makes sense. If the users want less size, then listen to them (add the RJ.5).
                RPi really gets is chops via WiFi anyway.

    Sure, a smaller and sturdier connector would be nice, but the changeover costs would be insane! Not to mention the fact that a more compact connector might not be something you could clip onto the end of a cable you're running the way we do with RJ-11&45. You can't crimp and clamp something the size of Micro USB.
