Oddbod Posted October 12, 2015 Posted October 12, 2015 Although this isn't the reason it's called A and B, but easy to remember. From the Cisco course: T568A for voice, T568B for data. Although as the majority of businesses use VoIP now, T568B is used predominantly.
Oaktech Posted October 13, 2015 Posted October 13, 2015 I want to start, but I get frustrated by crimping the plugs on as the wires seem to move away from the connectors. Anyone got any tips lol? Practice. Buy a bag of 100 crimps off ebay and just do it till your fingers bleed! The trick with them is to start with 5-10mm more conductor than you need to make it into the plug, get the conductors fanned out, straightened and then to lie nicely next to each other, then cut them off straight with a set of side cutters to the correct length and don't mess about get them straight in the plug! My first job in IT they got me to make custom length patch leads for the whole building which was over 1000 points. Those cabinets were f-ing immaculate and I got really good at making patch cables really quickly.
kearton Posted October 13, 2015 Posted October 13, 2015 (edited) Practice. Buy a bag of 100 crimps off ebay and just do it till your fingers bleed! +1 for that! I wish I had 1p for every one I've made over the past 18 years. Whilst on the subject, an IT teacher at my last school asked me to make him custon length patch cable many years ago, but neglected to say how long he needed it. We got on well so I thought I'd have a little laugh with him. Funnily enough he didn't want to keep it. I still keep it in my desk drawer to this day... Edited October 13, 2015 by kearton 2
dry Posted October 13, 2015 Posted October 13, 2015 One contractor I used brought some fancy-pants RJ45 connectors. They had a little plastic guide that you'd take out of them, thread each strand through the relevant hole in this guide (which would keep them in place) and then thread the whole assembly into the RJ45 connector. All this time I'd been fiddling with normal RJ45 connectors! It did feel like he was cheating a little bit though! Very similar to these: RJ45 Crimps + loadbar AMP NETCONNECT TE High Performance UTP Plug Connector
Gaz Posted October 13, 2015 Posted October 13, 2015 +1 for that! I wish I had 1p for every one I've made over the past 18 years.

[ATTACH=CONFIG]32642[/ATTACH] Haha I thought it was just me that made silly things like that. I made these back in 2005 Even made a crossover one, because why not lol.
ITGURU Posted October 13, 2015 Posted October 13, 2015 We just use the cheapo testers for checking connections (rj45) no fibre testing kit as all done by external contractors. as long as get all lights and a 1 gig connection i'm happy Would love to do a fibre course, but it's expensive business and for what little new runs we do it's not worth it.

Very similar to these: RJ45 Crimps + loadbar AMP NETCONNECT TE High Performance UTP Plug Connector Those are awful we had some in one place and think I threw them in the bin in the end as they took about 3x as long to do compared to normal ones and no excuse really its not hard to do it right.
Gaz Posted October 13, 2015 Posted October 13, 2015 A friend who used to work for a company that installed home entertainment, automation an security systems used to use these. https://www.blackbox.co.uk/gb-gb/si/1305/12819/CAT5e-EZ-RJ45-Modular-Plugs/V1.S1.O4 They are super easy to use but pretty expensive.
mikeyd101 Posted October 23, 2015 Posted October 23, 2015 In the UK we use the B standard as B is for British, A is as you've guessed for American. Ben I'm done for then as i'm a Brit working in America, I'll just use A on one end and B on the other
