Another big clearance sale guys. Hope the title is sufficient.
All Comsol Branded & Retail bagged Comsol Cat5e Patch cords. Does Gigabit.
Major warehouse clearance as we are relocating at the end of the month to a new factory.
All the smaller lengths have multiple colours available. Stock levels indicated are correct on each item.
Starting from $0.60 for 500mm up to 50m for $14.00.
All parcels dispatched by Eparcel, trackable. pickup available from St Marys if your in sydney
nice deal, but small order with shipping is about the same price as umart rrp (pickup, there's loads of umarts around)
Comsol is the same brand which is sold at Officeworks so it must be good cables. However Cat5e is quite a bit old now.
still does gigabit which is what most consumer routers do these days. and Comsol is listed on the EESS as a legitimate supplier. so insurances covered!
Quality cat5e does 2.5 Gbps over 100 m, and over very short lengths can reach up to 10 Gbps. They just never bothered to re-certify it for the higher speeds.
It is hard to find legit Cat6 cables anyway.
5E is totally fine for 99% of office end-device and residential use.
I prefer 5E simply because it's slightly more supple.
Don't we all.. ( ͡° ͜ʖ ͡°)
Well, 6A is stiffer and thicker…
Not anymore. Unshielded cat5e doesn't meet aus POE standards.
Surely it's fine if you aren't running a POE switch.
I'd go with rest of world over this one. Am not worried about shielding for 15w PoE devices. I've been doing it across five residences since around 2015.
I'd take Oz low voltage wiring standards a bit more seriously if they didn't mandate electricians for laying it, following the rest of the technologically sane world.
I could be wrong on this, but whenever the guys at work have laid out PoE phones, they don't worry about minor differences in cabling standards.
I use cat 5e patch cables between Poe switch to panel all the time. I've never had an issue.
I've also run Poe devices over existing cat 5e cabling without issue.
I'd never heard of this standard till you mentioned it.
@KernelOK: Wether or not you've "heard of" the standard is rather irrelevant.
I really detest the "Well I never had a problem" type anecdotes. Drink drivers say it all the god damned time. It's never a problem, until it is, then it's a problem.
Electricians "not worrying" about standards is the bane of my existence as a PM involved in fitouts.
Please, people don't hand wave or downvote a legitimate issue over standards because you don't like it, don't understand it, or find it inconvenient.
You're allowed to not care, but please don't try to justify being wilfully ignorant now that you know better. You can just not care.
Yes it's "less" relevant in residential settings when you don't have bundles of 50 run, all heating each other up, but it's still the standard.
Even Cat 6 U/UTP doesn't meet standard. F/UTP is the minimum, albeit yeah, it's slightly less flexi.
@Ademos: I just downvoted after reading this not because I disagree with the standard, but because I disagree with your logic.
I've worked with top tier networkig professionals planning trade floor fitouts, and nobody has given a stuff what they power PoE phones with.
This is from desk patch to phone, I've not paid attention to the rack to desk cabling, but this is a forum where people are buying stuff for home usage.
The standard, if it even it exists, is totally irrelevant to the Ozbargain audience.
How many Ozbargain readers are running 50m bundles of cable to 48 port PoE Cisco switches? And is anyone with a setup like this going to be buying bargain cable? Mine is either via work or it's self-terninated.
@Ademos: Without reference isn't your claim about UTP and POE an anecdote? I can't find any reference to that in AS/CA S009 2020. Besides, it makes zero sense to mandate shielding on DC wiring since there won't be any EM radiation anyway. The only recommendation around patch leads I've seen is to stick to bundle sizes of <= 12 cables IF using 30W+ POE devices on narrower gauges than 24AWG.
@Borkbork: There is a few conflicting standards these days. many an importer will bring in wire guages such as 30awg/32awg/34awg. but no standard exists for them. Category 6 & 6A are actually trademarked and copyrighted standards owned by ANSI/TIA used under free licence through ISO/IEC etc. and cablers are not really taught a lot by RTO's these days bar the bare basics. now if you go and ready AS-11801-6 it states that all POE & WAP installs must be done in Cat6a, however its one of those things that is "recommended but not enforced" because legally as long as you follow S009 and the products comply to S008 your backside is covered. I think we have a massive lack of standards advertising and also industry consultation. nobody really talks to each other in the industry wether your a contractor or supplier.
@execab: No, there aren't really conflicting standards. There's Australian standards. We're in Australia.
S009 states.
ES1, ES2 and ES3 remote Power Feeding can cause heat to rise in Cables which could be further increased under any of the following conditions:
(a) The Cables are bundled or encapsulated in thermal insulating material in the form of Conduit or Duct.
(b) The Cable conductors have cross-sectional area lower than 24 AWG (e.g. 28 AWG).
Which much of the cheap cat5 stuff is.
Among much other guidance and reference to other standards.
For the piddling cost difference there is just zero justifiable reason/point to use cat5 in 2023 or take the risk, really.
Again, y'all can downvote if "I don't like, the vibe and like, thing, and I'm a home user who doesn't give a shite" but you'll be wrong while you're doing it, and you can sit there in your wrongness, and be smugly wrong. That's fine.
please don't try to justify being wilfully ignorant now that you know better
Being force fed something is hardly 'knowing better'…
Australia is a nanny state. There is regulation for regulation just to keep morons in a job. Then there is the trade unions pushing unnecessary regulation to prop up tradies charging for a job any half experienced home owner can accomplish.
Some countries permit home owners to do their own 110/240v wiring and termination and while I don't personally see that as a brilliant idea, we should not be restricted to perform our own copper line, ethernet and coax extensions in our own premises.
@dmbminaret: the reason the rules exist is to protect things you do not own. for example, the power network is worth hundreds of billions of dollars, and uninsurable due to its sheer size. same goes for telecommunications networks. it is to protect what your interfacing with hence the reason for regulation. in many countries where low voltage work was unlicensed there are licensing measure being put in place, especially in places like the USA and gaining a national code because they see the importance of it as well. most people cannot see past their own home and do not understand what they are interfacing with. and the expenses that follow it. we are also in a land run by insurers, any form of non compliance and insurers will void claims and that spreads right across from home wiring to consumer products used in the home. whilst people like to want to dictate how things are done, the world is run by someone else
@execab: There's also the risk of injuring or killing someone. Imagine stuffing up the low voltage wiring which gets connected to your copper phone/NBN service and it causes 240V to hit the technician working on the telephone cabling down the street.
This isn't applicable once you're switched over to FTTP but the rules still apply nonetheless - there's still the potential to kill the new owner of your home or even a visitor due to incorrect wiring.
An electrician friend of mine was telling me some stories of the "interesting" mistakes that he has found over the years. It's amazing that people can have such poor understanding of what they're doing but think that they're capable of doing it properly - the Dunning Kruger effect is alive and well!
@OnTheMark: It's the same mentality as every white anting idiot that rages when they get a speeding fine.
They know the rules, they've been told the rules, they still think there's 400 words that justify why it shouldn't apply to them, because they're a smart, responsible person, and everyone else is the problem.
Watering the wind, I'm afraid.
@Ademos: Actually, the rules aren't known. I've only recently discovered these regulations after my FTTN stopped working and my ISP told me I needed to get someone to fix it.
Who do you get? A sparky or antenna installer? Regardless, neither trade would bother to look, quote or perform apparently.
Subsequently, I found the lead in cable in the ceiling, removed the small township of scotch locks entertaining unused extension points and reapplied new scotch locks to one single cable.
Now that cable goes to a small server rack in the garage which houses modem, pfsense box, UPS, patch panel and omada POE switch which feeds back through the ceiling to access points in other areas of the house.
Am I licenced? No. Is it an improvement and the same as any tradesperson would do? Yes. If this is likely to cause an issue to external infrastructure, it should be maintained by the infrastructure owners even with necessary costs to the consumer but this was never offered, nor obtainable. Maybe regulate that part first…

We had a qualified electrician at work that worked for the council water division as a supervisor and did sub-contract work on the side. He left half way through installing a bunch of NVRs and POE cameras throughout 5 sheds. I have recently finished the job and actually had to re-terminate a few cables to get the cameras to make connection. It has been mentioned also that my work looks so much more professional than his.
@dmbminaret: You know I was just sharing the parable of the driver that gets caught speeding but has a whinge le because "it shouldnt apply to me, im smarter than evertbody else, im a SAFE driver".
Just because you dont know, and someone you talked to doesnt know, doesnt mean it isnt known. Gwentyh Paltro and 50k of her idiot followers will INSIST that shoving lavender quartz up your clacker will cure covid or whatever. They're still wrong.
You wouldnt have a clue if your work is as good as a trades, because you arent a trade. You want an ACMA licenced cabler. Easy.
You might be good. You might even be better than some qualified people. But you are not a professional if youre not a professional, not even if the last professional you got was a lazy shithead.
Your works probably fine, so long as it doesnt touch the network side of telecommuncations network. Then its not fine, in fact its federal criminal offence under the telecommuncations act.
@Ademos: To make another analogy, comments in this thread are basically saying anybody who is not a mechanic and does their own oil change or brakes, will potentially cause the road infrastructure to deteriorate. Professional drivers are doomed to meet my potholes and die.
What constitutes permanent cabling? In the ceiling vs across the floor? Punch down connection vs RJ45? Purchased network cable vs self-crimped?
@Ademos: Ok. We've already established I am ignorant by by own submissions, but can you please explain to me how someone could receive a lethal voltage shock from my undertakings.
From what I understand, the lead-in cable used to carry around 50v DC for ringing analogue phones and drop to half that between rings. I have that cable plugged in to a 12v DC modem.
From what I can ascertain from Google searches is 2 pair cable might have a capacity of ~90v DC.
If any of this is correct:
A. How does the voltage get sent back to the exchange from my equipment?
B. I don't believe 48v (POE), 12v (modem) would be harmful if someway previous point did happen. 90v DC would not be pleasant and I assume 240v AC is physically impossible due to equipment blowing up and phone cable melting long before.
C. Would not a Telstra/NBN co tech be using PPE and taking precautions inline with WHS?
@dmbminaret: Stop asking @Ademos to justify anything on a technical basis. He's a project manager, so he's clearly too smart and too busy to deign answering anything based on technical merits. And too busy smugly accusing anyone who has actual experience, has done actual testing, or has even thought briefly about this of being smug.
Funny how this has somehow semi-shifted into a discussion about what an enterprise cabling deployment would be, from an Ozbargain deal where people will be running cables in bundles of… a single cable. Thermals. Riiiight.
Anything enterprise/corporate gets done by a contractor using 6A, I have no bloody idea why this thread has taking this turn, beyond someone jumping in from an irrelevant standpoint with "I must be right!!!!"
As an aside, I've been curious enough about this subject in the past to try using the crappiest flat Ethernet cable I could find to power PoE devices. There was no measurable thermal change with a short run and 802.11af. I didn't measure the wire gauge, it was probably something terrible like AWG30. Of course, this was just pissing about with my old home lab setup and to satisfy curiosity, it wasn't a permanent office deployment.
@rumblytangara: I'm also the only one who's quoted the actual standard correctly instead of hand waving in it's general direction and then coming up with complete horseshit, not reflected in it, to justify my incorrect opinion.
As a senior, technical PM I'm usually the only one holding the trades to account/their own standard. Literally my job. We make them rip shit out and do it again properly all the time.
It's not jumping in saying "I must be right". It's jumping in saying "this is the standard". I didn't write the standard. I cannot believe how many people want to piss, bitch and moan simply because they don't want to learn something new today. Good day to you mate.
I'm also the only one who's quoted the actual standard correctly instead of hand waving in it's general direction
Where does it indicate that 24 AWG Cat 5e doesn't meet the standard for POE?
If you mess with your own brakes, and kill someone, do you think you'd be liable?
CTP insurance?
@dmbminaret: Won't swerve the negligent manslaughter charge.
It's not about voltage/shock, again, it's about thermals.
@Ademos: Ok. I guess that question was more directed to @OnTheMark:

I expect you mean Cat 5e, as I'm sure no one is using 10/100 networks here. That said, @borkagork seems to be correct with findings:
https://www.ozbargain.com.au/comment/14375923/redir
https://community.fs.com/blog/will-28-awg-wire-work-with-pow…
I'm going to check my 5e cables today for wire gauge, but regardless, they're not in bundles of 12 let alone 2…so thermals is irrelevant for 30w POE evn if it is 28 AWG?
@dmbminaret: Theres multiple risk factor's, not multiple required conditions in combination. I sdmit it reads odd as an extract. Note the "any of" qualifier. Not "all of".
@dmbminaret: In my opinion, the likelihood is relatively low, but the risk is there nonetheless. Basically, it's another hole in the swiss cheese model - if you're aware of that term with regards to safety management.
If you don't have the required separation between low and high voltage wiring and something happens to cause the insulation to fail - e.g. chewed by rats/melts due to excess heat, etc, then high voltage can end up where it shouldn't be. If a linesman is working out in the street at the time and they happen to accidentally touch a wire that is energized with 240V, that could be the end of them.
Low likelihood, but high consequences, so still best to be avoided if possible.
Let's disregard the shielding aspect but if you are running long distances POE you want CAT6. CAT5 cables are usually 24AWG or 0.5106mm diameter. CAT6 is slightly thicker 23AWG or 0.5733mm diameter. The thicker copper of CAT6 has less electrical resistance will reduce voltage drop over long distances and thus less power load on your POE power supplies. Less power means it runs cooler therefore it will be more reliable.
Of course there are some exceptions, you can get super thick CAT5 in 22AWG which is great for POE applications. And on the other hand CAT6 in super weak and thin 30AWG which will burn in no time if you try to POE 100 Watts. So check the cables copper thickness, there usually printed on them.
I do appreciate the super thin cables which I carry for work daily I can fit a longer length in my bag compared to a thick one.
My router has 1x 2.5gbps and 3x 1gbps, so cat5e is good for me
Nbn box is 1gbps isn't it as well? So cat 5e maxes out that port
Any recommendations for cat proof cat 6 cables?
My cat ate through my last one.
Not even joking.
Replace it with power cable. Sorted.
Need a dog cable?
You can get specialty outdoor cables with tougher outer shield.
Don't get the Cat6E ones (E is short for Eat)
you can try an outdoor rated cable. they have a nylon sheath and rodent protection
Looks like free pickup NSW
What area?
69-73 Christie Street, Saint Marys NSW
I have more ethernet cables than I can ever use, but now I want the pink ones.
Wow this is cheap as for branded I'm grabbing the 50m for a project.
Are these the ones you need to connect your devices with Ethernet port at various rooms for hard wired houses?
yes
Thanks mate.. Then they are quite cheap. Bunnings sell them for $6-7 each
Thanks OP, needed some cables.
Are they solid copper or the cheap shit (CCA)?
stranded copper, but yes pure copper, you cant have solid copper in patch cords under 20m. CCA is illegal to sell in Australia although i do see quiet a lot of IT Vendors & Computer stores selling them which is odd
How do you tell if it's CCA without cutting it apart and scraping off the copper plating?
You need to cut it and scrape the copper plating.
You can measure the resistance per meter, since aluminium is a poor conductor (and not suitable for many power/data applications).
@brenwildman: Although copper is definitely a better conductor, I think that to call aluminium a poor conductor is completely wrong - it's used as a conductor in a lot of applications:
https://www.wilsonpowersolutions.co.uk/app/uploads/WPS_Alumi…
@OnTheMark: Very true! especially in power applications And RF. Its just prohibited in Australia for Category based cabling. Back in the early days of POE we saw some interesting stuff happen with CCA Cable. hence the reason they banned it. in many countries it is actually acceptable to use.
Big thanks to all. over 900 orders since yesterday! We will be busy packing and shipping out today and tomorrow!
Good price, but shipping kills for a small order.
