![]() ![]() The plastic insert looks like a "+" sign if you crossection it and each of the 4 pairs of wire then can fit in each quadrant of that insert. The most common way by manufacturers to achieve this distance is a plastic insert that runs the entire length of the cable. One of the CAT6 specs requires separation distance of the twisted pairs to prevent cross talk. Each iteration of the spec from CAT5 to CAT6 simply makes for more stringent requirements. Internally, much tighter specs need to be adhered to ensure conformity to each of the standards. It has to in order to be physically compatible and give you that satisfying "click" when you plug things in. With the use of RJ45 connectors we are then forced to use the familiar 4-pair signal wire. The connectors are used for backwards compatibility. Among those things are the RJ45 connectors (clear plastic male plugs as well as the female jacks). Sorry, I know this is resurecting an old thread, but I felt like I needed to put my 2 cents in.simply because I've gone through this recently at my new workplace and am looking into "testing" all the lines that have been run in the last 10 years.ĬAT5, CAT5e and CAT6 share a few common requirements. Cabling systems will typically be installed by certified installators, and be validated end-to-end after installation by measuring that they meet or exceed an agreed level of performance. But this is a name-brand structured cabling system. The same brand uses a "smart connector" for the 8P8C plugs as well. Here is a little video that shows how some modern structured cabling systems use an insert / form. While there can and should be differences in how plugs are designed, in the no-name space I don't think you'll find a consistent set of differences between no-name Cat5 and Cat6 plugs. Regarding OP's link to a no-name plug, I think it's mostly marketing. Solid wiring is often used in building wiring. See John Gardeniers answer regarding stranded / solid wiring these should use different plugs.This is to minimize crosstalk and noise near the plug (where the cable is un-twisted, and much more susceptible to interference). Many cabling systems now use a little 'form' to hold the wires in place before the plug. More and more manufacturers are updating their cabling systems, both to allow faster cabling work, and to ensure more consistent and/or higher quality.If the wires are thicker, the plugs are different. 23 gauge copper wiring (thicker wires) is more common in Cat6 installations than in Cat5 in my experience. ![]() Having said that, the following comes to mind: I would guess - but I'm not 100% sure - that the standards are mainly concerned with externally observable characteristics of the cabling such as crosstalk and attenuation, and leave the internal implementation details mostly up to each manufacturer. To the best of my knowledge, the standards themselves do not mandate any changes to the plugs. ![]()
