How To Choose The Best Bulk Cat6 Cable
Picking a spool of bulk cable is different from grabbing a short patch cord. The cable in your walls needs to meet fire codes, handle power delivery, and stay reliable for a decade. Here are the two most important specs to lock down before you buy.
Conductor Material: Bare Copper vs. Copper-Clad Aluminum (CCA)
The conductor inside the jacket determines signal quality how much power the cable can carry for PoE devices like security cameras. Bare copper (or solid copper) is the standard you want — it conducts better, resists corrosion, and bends without breaking. Copper-clad aluminum (CCA) is an aluminum core coated with copper. It is cheaper, but it also breaks more easily under bending and cannot safely carry power for higher-wattage PoE gear. Every verified review in our data shows that buyers who scratch-check their cable (exposing the core color) catch CCA cables flagged by disappointed owners.
Fire Rating: CM, CMR, or CMP?
The jacket rating is not optional — local building codes often require a specific type for in-wall runs. CM (Communications) is the baseline for a single floor inside a wall. CMR (Riser) adds fire resistance for vertical runs between floors, like in a multi-story home or office. CMP (Plenum) is the highest rating for air-handling spaces like drop ceilings or HVAC ducts; it uses a low-smoke, fire-retardant material. Picking CMR or CMP when you need it keeps your installation safe and code-compliant. Picking CM for a riser run could fail inspection.

In‑Depth Reviews
1. Cable Matters [UL Listed] 10Gbps in-Wall (CM) Rated 23AWG Bare Copper Cat 6 Cable – 500ft
Our pick — over 4.5★ from 500+ verified ratings; the strongest balance of quality and price.
The 500-foot spool that handles PoE cameras at 175 feet without a sweat.
You get safe power delivery to devices like PoE cameras and wireless access points because this Cable Matters spool uses 23AWG bare copper conductors — not copper-clad aluminum. It carries a UL listing (E485863, a safety certification from Underwriters Laboratories) and meets TIA/EIA 568-C.2 standards (the industry wiring specs), so the build is traceable, not generic. The 500-foot length is 500 feet, while the Big-A spool is 1000 feet, but for a single-floor home or office, it is often exactly what you need without the waste of a massive box.
This cable is rated CM (in-wall) and supports up to 550 MHz bandwidth — plenty of headroom for 10-Gigabit Ethernet and backward compatibility with your existing Cat5e gear. The foot-marked jacket lets you track how much cable you have left as you pull. One buyer reports using it for surveillance PoE cameras as far away as 175 feet, noting it provides sufficient power to the cameras as well as excellent connectivity for 4K. That kind of distance is a strong real-world test for any bulk spool.
Compared to the Cable Matters CMR 300ft spool, this one is a better fit for single-floor work where you do not need the extra fire resistance of a riser rating (CMR, or Communications Multipurpose Cable, Riser). The trade-off is that if you are running between floors in a multi-story building, you will want the CMR version instead. For straightforward in-wall runs, this is a solid choice.
Why It Wins
- Verified solid bare copper conductors handle PoE+ and PoE++ reliably
- High 4.7 rating from over 500 reviews confirms consistent quality
- Foot-marked jacket and easy-pull box reduce waste during installation
The Limit
- CM rating means it is not code-approved for riser (between-floor) runs
- 500-foot length may fall short for very large homes or multi-unit projects
Reach for this if: you are running cable inside one floor of a home or office and need a reliable, code-compliant spool that can power PoE gear without issues.
Look elsewhere if: your run goes between floors or you need the maximum fire safety of a plenum-rated jacket.
2. Cable Matters [UL Listed] 10Gbps in-Wall Riser Rated (CMR) 23AWG Bare Copper Cat6 Ethernet Cable – 300ft
The 300-foot riser-rated spool for clean vertical runs between floors.
This Cable Matters spool swaps the CM rating for a CMR (Riser) jacket, meaning it is built with a superior fire-resistant material that meets code for vertical runs between floors in residential and commercial buildings. It still uses the same 23AWG bare copper conductors as the CM version, so you get the same strong signal and power delivery for PoE, PoE+, and PoE++. The 300-foot length is shorter than the Big-A 1000ft reel, but it is a practical size for wiring a few rooms or floors without half a spool left over.
The cable supports a data transfer rate of 10 Gigabits Per Second at 550 MHz frequency (the signal bandwidth) and comes on an easy-pull reel that one reviewer called “easy to work with” for a beginner. A buyer who used it for a standard 1Gbps home network reported that the cable performed exactly as expected, noting the sheathing is firm without being too stiff and the conductors are solid copper and not aluminum — a common problem with cheaper cables. If you are taking the time to run cable in your attic, this is the kind of quality that means you only do it once.
Where this differs from the CM-rated option above is entirely about safety and code. If you are running cable between floors, a riser rating keeps the installation legit. The catch is the 300-foot length might feel tight if you are wiring a large house with long paths, but it is spot-on for a focused project.
Why It Wins
- CMR (Riser) rating means it is code-compliant for vertical runs between floors
- Buyers confirm it runs cleanly through walls without snagging or kinking
- 10Gbps support with 550 MHz bandwidth handles high-demand applications
The Limit
- 300-foot length may not be enough for a whole-house project with long runs
- CMR jacket is slightly stiffer than CM, which can make tight corners a bit harder
Pick this for: a multi-story home or office where you need certified CMR cable for between-floor runs and prefer bare copper over CCA.
skip it if: your whole project is on one floor — the CM-rated 500ft spool gives you more cable at a similar cost.
3. Big-A Cat 6 Ethernet Cable 1000ft Blue, Cat6 Bulk Cable, 23AWG Solid UTP CMR Riser
A full 1000-foot riser-rated spool for the buyer who hates running out mid-project.
The Big-A spool gives you 1000 feet of 23AWG solid conductors with a CMR riser rating (fire-resistant for vertical runs between floors), which is double the length of the Cable Matters CM 500ft spool. That extra cable matters when you are wiring a whole house — five PoE cameras, three computers, a TV, and a network switch add up fast, and one buyer confirmed they did exactly that and still had a bunch left. The solid core construction means this is not the soft, cheap type, as one reviewer put it, and that rigidity helps with clean terminations and stable signal over long runs.
This cable supports Gigabit Ethernet and short-run 10 Gigabit applications at 550 MHz. It is rated CMR, so it is safe for runs between floors in a residential or commercial building. The pull box includes sequential footage markings and smooth payout to prevent tangles. One buyer who used it for a friend’s house rewiring called it clean and easy to install for a home network or server room bulk use.
The main trade-off is that the Big-A brand is less known than Cable Matters, so the traceability of the UL listing matters less if you need a specific certification for a commercial job. For a homeowner doing a full rewire, the 1000-foot length and CMR rating make it a strong value.
Why It Works
- 1000-foot spool covers whole-house projects without needing a second box
- CMR riser rating means it is safe for vertical runs between floors
- Buyers confirm solid core construction, not the soft type found in cheaper cables
The Catch
- Big-A is not a major networking brand, so certification detail is lighter than Cable Matters
- Some buyers noted delivery took longer than expected
Go for it if: you need one spool to handle the entire wiring job — cameras, computers, everything — and you want CMR safety for any between-floor runs.
Look at the Cable Matters CM 500ft if: your project is smaller and you prefer a brand with more verified reviews showing consistent quality.
4. Newyork Cables CAT6 Plenum Cable 1000ft, 23AWG, UTP, 550MHz 10Gbps Most Certified (CMP) Rated
The plenum-rated 1000-footer for air ducts and drop ceilings where code is strict.
This Newyork Cables spool is built for the strictest indoor environments — plenum spaces like air ducts, drop ceilings, and HVAC returns. It carries a CMP (Plenum) rating, using Fluorinated Ethylene Propylene (FEP) in the jacket to limit flame spread and toxic smoke. That makes it the right choice if you are running cable in commercial buildings or residential spaces where local code demands plenum-rated materials. The solid conductors support 10 Gigabit speed and 550 MHz bandwidth, and the box includes clear foot markers for tracking length.
One DIY buyer who wired their older home with this cable said it feels very sturdy, thick, and durable and rolled well with easy payout. They made an 80-foot run plus two 10-foot patch cables and reported great signal quality. Another reviewer called it their favorite cable, noting it is easy to pull and terminate. However, a critical review flags that the cable is CCA (copper-clad aluminum) and not solid copper — the buyer felt the listing was misleading. This is a serious warning: if you need bare copper for PoE reliability, you should verify before cutting.
Compared to the CMR-rated options above, the CMP cable is stiffer and more expensive, but it is the only choice for plenum-rated installations. The 3.8-star average from over 500 reviews is lower than other picks here, driven largely by the CCA vs. bare copper confusion in reviews.
Why It Matters
- CMP plenum rating is the highest fire safety standard for indoor cable
- 1000-foot length with easy-pull box and foot markers
- Buyers report easy termination and strong signal quality on long runs
The Concern
- Multiple buyer reviews state the cable is CCA (copper-clad aluminum), not solid bare copper
- Stiffer plenum jacket is harder to work with in tight spaces than CM or CMR
Use this when: you absolutely need a CMP plenum rating for a code-compliant run in air-handling spaces and you have confirmed the conductor type meets your needs.
Avoid it if: you need verified bare copper for PoE devices — check the return policy and consider the Rapink or Cable Matters spools.
5. Rapink Cat6 Ethernet Cable 1000ft, 23AWG Solid Bare Copper 10G Support, UTP 550MHz, POE Support
The 1000-foot spool built for high-wattage PoE++ and large-scale projects.
The Rapink spool is a straight-up, no-compromise choice for demanding installations. It uses 23AWG solid bare copper (0.52mm conductors) and explicitly supports Power over Ethernet standards up to PoE++ (802.3bt), which covers high-draw devices like pan-tilt-zoom cameras and high-power access points. It passed both TIA Cat 6 Permanent Link and Channel tests, giving you a spec-sheet level of assurance that is rare in the budget tier. The 1000-foot length comes in a tangle-free box with markers every 2 feet starting at 1000 and decreasing, so you always know your remaining length.
One buyer wired a full Ubiquiti UniFi mesh system with a 2.5 GbE WAN connection using this cable, and confirmed it is indeed solid bare copper, twisted pair, unshielded with a divider and pull string. They reported it worked exactly as advertised. Another user ran it for surveillance cameras and called the quality great. The data transfer rate is 10 Gigabits Per Second, and the cable is super easy to terminate with pass-through RJ45 connectors and keystone jacks.
The biggest difference between this and the Cable Matters CM spool is the 1000-foot length — 1000 feet compared to 500 feet, same bare-copper quality. The trade-off is that Rapink does not specify an explicit fire rating in the data, so you cannot assume it meets CM, CMR, or CMP. That makes it less suitable for code-required in-wall installations where an inspector checks the jacket markings. For open-air runs, patch cables, or non-inspected spaces, it is a powerhouse.
Why It Excels
- Explicitly supports PoE++ (IEEE 802.3bt) for high-power devices
- Bare copper verified by multiple buyers, not copper-clad aluminum
- TIA Cat 6 test pass certification adds real standards compliance
The Gap
- No explicit CM/CMR/CMP fire rating in the specs — not ideal for code-inspected in-wall runs
- Less known brand with fewer reviews than Cable Matters options
Buy this for: large projects where you need 1000 feet of verified bare copper that handles PoE++ and you are comfortable with the unlisted fire rating.
Choose the Cable Matters CMR 300ft if: your installation requires a clear riser rating for between-floor runs.
Understanding the Specs
Conductor Gauge (AWG) & Material
The gauge tells you the thickness of the copper wire inside. For bulk Cat6 cable, 23AWG is the standard spec — it is thick enough to carry power for PoE devices without significant voltage drop. The material matters even more: solid bare copper conducts electricity and data better than copper-clad aluminum (CCA) and is far more durable when you bend and terminate it. A buyer report we saw flagged a spool as CCA when they expected solid copper, so this is a real risk to watch for.
Fire Ratings (CM / CMR / CMP)
These ratings are not about speed; they are about safety in a fire. CM (Communications) is the baseline for in-wall use. CMR (Riser) adds fire resistance for cable that runs between floors. CMP (Plenum) is the strictest — it uses a low-smoke jacket for air-handling spaces like ducts and drop ceilings. Building codes often require a specific rating depending on where the cable runs. You can see the difference clearly in our picks: the Cable Matters CM 500ft (CM) versus the Cable Matters CMR 300ft (CMR) versus the Newyork Cables Plenum 1000ft (CMP). Three different jobs, three different ratings.
