Choosing bulk Ethernet cable is simple when you work through it step by step: speed, rating, shielding, conductor, length and colour. This guide walks through each choice so you can order the right cable the first time.
1. Pick the category by speed
| Category | Bandwidth | Speed |
|---|---|---|
| Cat5e | 350 MHz | Gigabit Ethernet 10/100/1000 Mbps |
| Cat6 | 550 MHz | Gigabit Ethernet 10/100/1000 Mbps |
| Cat6a | 750 MHz | 10-Gigabit Ethernet |
| Cat7 | 850 MHz | 10GBase-T |
For most offices and homes, Cat6 is enough. For 10-Gigabit networks and data centers, choose Cat6a or Cat7. Read our Cat6 vs Cat6a guide for a closer comparison.
2. Pick the rating by where the cable runs
Use CMP plenum cable in air-handling spaces, CMR riser cable for runs between floors, and CMX outdoor or direct burial cable outside and underground. Read our plenum vs riser guide for the details.
3. Choose shielding
Unshielded twisted pair (UTP) is the standard choice and is enough for most runs. Choose shielded cable (F/UTP or STP) where there is electrical noise from motors, lights or heavy equipment, or where the cable runs near power lines.
4. Check the conductor
Look for 100% bare copper conductors. Copper-clad aluminum (CCA) looks similar and costs less, but it does not carry data as far or as reliably, and it is not allowed in many specifications. Every bulk Ethernet cable from Red Cable Technology is made with 100% bare copper conductors.
5. Choose length, packaging and colour
Our bulk Ethernet cables come in 1000 ft boxes, with Cat7 on a 1000 ft reel. Count the runs you need and add a little extra for each run. Many of our cables come in a choice of colours, so you can match the cable to the job or colour-code your runs.
6. Check ETL listing and warranty
ETL-listed cables are tested to meet the standard printed on the jacket. Our ETL-listed cables carry a 25-year warranty. Our other cables carry a 20-year warranty.
