What separates quality Ethernet cable from non-compliant cable
The Ethernet cable market in Australia has a significant quality problem. Cable sold under recognised category names (Cat6, Cat6a) does not always meet the standard it claims to. Non-compliant conductors, inaccurate AWG markings, missing RCM compliance, and untested performance specifications are all present in the market, including on products sold through mainstream online platforms. For a registered cabler, specifying or installing non-compliant cable is not just a performance risk: it is a compliance and liability issue under the Telecommunications Act 1997 and AS/CA S008.
This guide covers every quality indicator you should verify before specifying or purchasing Ethernet cable for any Australian installation. For the specific dangers of CCA (copper clad aluminium) cable and the legal consequences of using it, see our CCA cable guide. For category specifications (Cat5e through Cat8), see our Ethernet category standards reference. For shielding selection, see our Cable Shielding Guide.
1. Conductor material: the most important quality indicator
The conductor is the copper wire inside each pair. In a compliant Ethernet cable, every conductor must be 100% solid copper. There are no acceptable alternatives for customer cabling installations in Australia.
The two non-compliant conductor types commonly found in the market are copper clad aluminium (CCA) and copper clad steel (CCS). Both use a base metal core with a thin copper coating. Both are prohibited under AS/CA S008. CCA in particular is a serious safety risk under PoE applications: its electrical resistance is approximately 40% higher than solid copper, which causes dangerous heat buildup in bundled cable runs under sustained current loads.
The terms "pure copper" and "oxygen-free copper" on a product label refer to the same material: solid copper conductor that has not been recycled or reclaimed. Both terms indicate a compliant conductor. If a product listing does not explicitly state "solid copper" or "pure copper" and cannot provide an AS/CA S008 datasheet, treat it as non-compliant until proven otherwise.
How to verify on site: strip back 10mm of jacket and insulation from a conductor end. Solid copper is uniformly copper-coloured throughout the cross section. CCA shows a silver aluminium core at the cut face. The difference is immediately visible to the naked eye.
For the full detail on CCA identification, legal penalties, and real-world failure examples, see our CCA cable guide.
2. AWG: conductor size and why it matters
AWG (American Wire Gauge) is the measurement of conductor diameter. In Ethernet cable, the lower the AWG number, the thicker the conductor. Thicker conductors have lower electrical resistance, which directly affects performance over distance and safety under PoE loads.
| Category | Standard AWG (solid) | PoE suitability | Notes |
|---|---|---|---|
| Cat5e | 24 AWG | 802.3af and 802.3at only | Not recommended for 802.3bt in bundled runs |
| Cat6 | 23 AWG | 802.3af, 802.3at, and 802.3bt Type 3 | Suitable for most PoE applications |
| Cat6a | 23 AWG | All PoE standards including 802.3bt Type 4 | Recommended for all new commercial installations |
AWG is printed on the cable jacket as part of the print legend. A cable sold as Cat6 but printed with "24AWG" rather than "23AWG" is not meeting the Cat6 specification correctly. Always verify the AWG marking matches the stated category.
For patch leads (stranded conductors), the AWG is higher (thinner) than bulk cable because stranded conductors are more flexible but carry slightly higher resistance. Quality slim patch leads use 28 AWG stranded conductors, which is correct for short patch distances (0.25m to 5m) but not suitable for horizontal runs. Solid conductor bulk cable should always be used for permanent infrastructure runs.
3. RCM compliance and AS/CA S008: the Australian compliance marks
The RCM (Regulatory Compliance Mark) is the mandatory compliance mark for customer cabling products sold in Australia. It replaces the older A-Tick mark and signifies that a product has been tested and complies with the applicable Australian standards including AS/CA S008. A cable without an RCM mark printed on its jacket cannot legally be used in a customer cabling installation in Australia.
The AS/CA S008 standard covers conductor material requirements (solid or plated copper only), UV compliance for outdoor cables, copper wire sizing, colour coding, outdoor cable properties, and flammability characteristics. A cable claiming AS/CA S008 compliance must meet all of these requirements, not just the electrical performance specifications.
How to verify: the RCM mark and the text "AS/CA S008" should both be visible in the print legend printed along the cable jacket. If purchasing in bulk or from a new supplier, ask for the datasheet or compliance documentation. Access Communications' RCM (SAA) number is E4073. For the full explanation of what the RCM means and how to verify compliance, see our Product Compliance guide.
4. Fluke testing: the difference between passing and performing
There are two very different levels of cable testing and the distinction matters enormously in practice.
A basic cable tester checks continuity: are all eight conductors connected correctly from end to end, with no crossed pairs or shorts. This confirms the cable is wired correctly but tells you nothing about its electrical performance under real network conditions. Every cable should pass basic continuity testing; it is the minimum, not the standard.
Fluke certification is a fundamentally different process. A Fluke DSX or equivalent certifier tests every electrical parameter that determines whether a cable will reliably support the data rate and bandwidth of its stated category: insertion loss, near-end crosstalk (NEXT), power sum crosstalk (PS-NEXT), return loss, propagation delay, and delay skew, all measured against the TIA/EIA and ISO/IEC thresholds for that category. A cable that is Fluke-certified to exceed TIA standards has been verified to perform above the minimum specification, which means it maintains a performance margin that absorbs real-world installation variables: suboptimal terminations, tight bends, bundled cable heat, and environmental noise.
Cables that only just meet the standard in a controlled lab environment routinely fail to perform post-installation when those variables are present. Fluke-certified cable that exceeds the standard has the headroom to perform reliably regardless. All Datamaster Ethernet cable is Fluke tested to exceed TIA and Australian standards before it leaves the factory.
5. Solid vs stranded conductors: matching the cable to the application
Solid conductor cable uses a single solid copper wire in each conductor position. Stranded conductor cable uses multiple thin copper strands twisted together. Each is designed for a specific application and using the wrong type in the wrong place causes performance problems and premature failure.
| Conductor type | Correct application | Why |
|---|---|---|
| Solid | Horizontal runs, in-wall, ceiling, conduit, patch panels, keystones | Lower resistance over distance, designed for permanent installation with minimal flexing |
| Stranded | Patch leads, equipment cords, any cable that is regularly plugged and unplugged | More flexible, resists fatigue from repeated bending, suited to short runs (0.25m to 5m) |
Using stranded cable for horizontal infrastructure runs is a common mistake on retrofit jobs where patch leads are pulled through walls or ceilings to save cost. Stranded cable has higher resistance than solid at the same AWG and is not rated for horizontal run performance. Use solid conductor bulk cable for all permanent infrastructure and stranded patch leads for all equipment connections.
6. Jacket type: matching the cable to the environment
The jacket material determines where the cable can be safely and compliantly installed. Using the wrong jacket type in the wrong environment is both a performance failure and a compliance failure.
| Jacket type | Correct environment | Do not use for |
|---|---|---|
| PVC | Standard indoor residential and commercial runs | Any outdoor or UV-exposed run. PVC degrades within 12 to 18 months under AU UV levels. |
| PE (UV-stabilised) | Outdoor above-ground runs exposed to sun, UV, weather | Direct burial without gel fill. PE resists UV but is not moisture-proof underground. |
| Gel-filled PE | Direct burial, underground conduit, wet environments | Indoor runs. Gel fill is unnecessary indoors and makes termination messier. |
| LSZH | Public buildings, hospitals, schools, enclosed spaces where fire safety is critical | Outdoor runs. LSZH is not UV-resistant. |
For the full breakdown of jacket types and the Australian building code requirements that govern them, see our Ethernet jacket types guide. For outdoor cable selection specifically, see our Network Weatherproofing Guide.
7. How to read the cable jacket print legend
Every piece of compliant Ethernet cable has a print legend running along the outer jacket. This is the fastest and most reliable way to verify what you are actually buying or installing. Here is what each element means.
A typical compliant jacket print looks like this:
DATAMASTER Cat6 U/UTP 4PR 23AWG SOLID COPPER PE UV AS/CA S008 RCM E4073
| Print element | What it means | What to look for |
|---|---|---|
| Cat6 / Cat6a / Cat5e | The performance category the cable is rated to | Must match what you ordered. "Cat6e" is not a real standard. |
| U/UTP, F/UTP, S/FTP | Shielding type | Must match the specification for the environment. See the shielding guide. |
| 4PR | Four twisted pairs (eight conductors) | All modern Ethernet cable is 4PR. If it says 2PR it is telephone cable. |
| 23AWG / 24AWG | Conductor diameter | Cat6 and Cat6a should show 23AWG. Cat5e shows 24AWG. Verify against category. |
| SOLID COPPER or BARE COPPER | Conductor material | Must be present. If absent, or if it says CCA, do not use for customer cabling. |
| PVC / PE / LSZH | Jacket material | Must match the installation environment. |
| AS/CA S008 | Australian standard compliance | Must be present on any cable used for AU customer cabling installations. |
| RCM + supplier number | Regulatory Compliance Mark | Must be present. Access Communications RCM number is E4073. |
If a cable's jacket print is missing any of the above elements, or if the print is illegible or inconsistent along the length of the cable, it is a red flag. Compliant, quality cable has a clear, consistent print legend that allows you to verify every specification without needing to contact the manufacturer.
8. Warranty: what it covers and what it means in practice
A genuine lifetime warranty on Ethernet cable is only possible when the manufacturer has verified performance through independent testing and stands behind that verification with a long-term guarantee. It is not a marketing claim; it is a statement of confidence in the manufacturing process and quality control.
When evaluating a warranty, the key questions are: what triggers a warranty claim, what is excluded, who bears the cost of replacement, and whether the warranty covers the product only or the consequential losses from a failed installation. Most warranties cover manufacturing defects only and exclude misuse, incorrect installation, lightning damage, and accidental damage. The warranty on Access Communications-manufactured products (including Datamaster cable) is a limited lifetime warranty covering production and material defects from the date of purchase.
What is not covered: accidents, misuse, poor maintenance, electrical overloads including lightning, incorrect installation, DIY installation by uncertified persons, tampered outer casing, and transportation costs for service calls. Replacement cannot exceed the cost of the item under warranty.
Note that the lifetime warranty applies to Access Communications-manufactured products only. Third-party brands carry their own manufacturer warranties.
Frequently asked questions
How can I tell if a cable is CCA just by looking at the jacket?
Check the jacket print legend. A compliant solid copper cable will print "solid copper", "bare copper", or "pure copper" on the jacket alongside the AS/CA S008 and RCM marks. If none of those terms appear, or if the print shows "CCA", the cable is non-compliant. You can also cut a conductor end and inspect the cross section: solid copper is uniformly copper-coloured throughout, while CCA shows a silver aluminium core. For the full identification guide and legal penalties, see our CCA cable guide.
Does a higher category cable always mean better quality?
Not necessarily. A higher category specifies higher performance thresholds, but a poorly manufactured Cat6a cable that does not meet its own specification is worse than a properly manufactured Cat5e. Category rating and build quality are separate things. A cable can be labelled Cat6a and still use CCA conductors, incorrect AWG, or untested performance specifications. Always verify the quality indicators above regardless of the stated category.
What does "exceeds TIA standards" actually mean?
TIA (Telecommunications Industry Association) standards define the minimum performance a cable must achieve to be certified at a given category. A cable that "meets" the standard passes at or above the minimum threshold. A cable that "exceeds" the standard performs measurably above the minimum, which means it retains a performance margin when installed in real-world conditions where temperature, bundling, termination quality, and interference all reduce performance from the controlled lab baseline. Fluke-certified cable that exceeds the standard is more reliable post-installation than cable that merely meets it.
Is there a difference between patch leads and bulk cable quality standards?
Yes. Bulk cable (solid conductor) is tested and certified for horizontal runs up to 100 metres. Patch leads (stranded conductor) are tested and certified for short equipment connections (typically 0.25m to 5m). The performance standards are different because the applications are different. A quality patch lead must meet the same category electrical specifications as bulk cable over its rated distance, plus durability requirements for repeated plugging and unplugging. Gold-plated RJ45 connectors (50 micron gold plating) resist corrosion and maintain conductivity over tens of thousands of insertion cycles, which is why they are specified on quality patch leads rather than cheaper tin-plated alternatives.
Can I use the same cable for both data and PoE?
Yes, provided the cable meets the PoE standard's requirements. The key factors are conductor material (solid copper only, never CCA), conductor size (23 AWG for Cat6 and Cat6a), and for higher-power 802.3bt applications, the category rating and bundling conditions. See the AWG table above for the full breakdown by PoE standard.
What is the RoHS mark and does it matter for Australian installations?
RoHS (Restriction of Hazardous Substances) is a European standard restricting the use of specific hazardous materials in electrical and electronic equipment. While it is not an Australian mandatory requirement, RoHS compliance indicates the cable has been manufactured without lead, mercury, cadmium, hexavalent chromium, or halogenated flame retardants. For installations in sensitive environments such as schools, hospitals, or food production facilities, RoHS compliance is worth specifying.
