Cat8 Patch Cables | 40 Gbps S/FTP 2000 MHz, Flat and Round, 0.5 to 25 ft, 24 AWG Bare Copper
Cat8 S/FTP patch cables for 40GBASE-T, 2000 MHz, 0.5 ft to 25 ft, flat and round. 24 AWG stranded bare copper, braid-over-foil shielding on every pair, gold-plated shielded RJ45, backward compatible with Cat6A, Cat6 and Cat5e jacks. Built for the 30 m channel: top-of-rack switch to server, SAN and storage links, 25G and 40G uplinks where a DAC is too short or too stiff. Same-day shipping on in-stock items; case pricing for data-center builds.
Flat or round? Round for cabinets, cable managers and bundles, the reference construction. Flat for under-carpet, desk-edge and behind wall-mount switches; not for bundles or vertical managers. Length: keep the whole channel, both cords included, under 30 m or 40GBASE-T will not train.

Shielded cords need a grounded rack and panel (TIA-607); for general patching where that is not in place, 550 MHz Cat6 UTP is the right cord. Guides: Cat6 vs Cat6A vs Cat8, PoE power budget. Fiber for longer runs: fiber optic patch cables. Distributor and contractor pricing.
Cat 8 Ethernet Cable FAQ
1. What is a Cat 8 Ethernet cable?
Cat 8 is the newest ANSI/TIA-568.2-D copper standard, rated for 40 Gbps and 2000 MHz with mandatory shielding to crush crosstalk and EMI.
2. How fast are Conversions Tech Cat 8 cables?
They deliver 40 Gbps up to 30 m, auto-negotiating down to 25G/10G/1G when connected to legacy gear.
3. What bandwidth do they support?
2 GHz (2000 MHz)—four times the bandwidth of Cat 6A, ensuring headroom for future encoding schemes.
4. What’s the maximum channel length?
30 m (≈100 ft) end-to-end or 24 m permanent link for 25/40 G. At 10 G or lower, Cat 8 reaches the classic 100 m.
5. Is Cat 8 backward-compatible with Cat 6A/6/5e?
Yes—our RJ-45 Class I connectors snap into any 8P8C port and auto-negotiate to the highest common speed.
6. Cat 8 vs. Cat 6A—what’s the real-world difference?
Cat 6A tops out at 10 Gbps/500 MHz; Cat 8 quadruples both bandwidth and throughput, letting you run one 40 G link instead of four 10 G links.
7. What type of shielding do Conversions Tech cables use?
Each pair is foil-wrapped (F/FTP) and then covered by an overall tinned-copper braid, providing >80 dB alien-crosstalk rejection.
8. Are the conductors 100 % copper?
Absolutely. We use solid bare copper (22 AWG in bulk, 26 AWG in slim patch) for ultra-low DC resistance and full PoE ++ headroom—never CCA.
9. What wire gauge does Cat 8 use?
Bulk cable ships in heavy-duty 22 AWG; our flexible patch leads use 26 AWG stranded conductors.
10. Do they support PoE, PoE+, and PoE ++?
Yes—up to the full IEEE 802.3bt Type 4 spec (90 W) with plenty of thermal headroom.
11. Does Cat 8 reduce latency?
Physical cable latency is already microseconds, but Cat 8’s lower insertion loss and shielding cut retransmits, giving a cleaner, more stable link for gaming and VoIP.
12. Can I run Cat 8 outdoors or direct-burial?
Yes—choose our Cat 8 Direct-Burial variant with UV-resistant LLDPE jacket and gel-filled core for water blocking. Just ground the drain wire at entry.
13. Do you offer plenum-rated Cat 8?
We stock CMP plenum and CMR riser jackets, each ETL-verified to NFPA 262 flame and smoke standards.
14. What’s the minimum bend radius?
Roughly 4 × OD. For our 7.8 mm bulk cable that’s ~31 mm (1.2 in).
15. How do I terminate Cat 8?
Use shielded Cat 8 plugs or tool-less keystones: strip 1″, fan pairs, clamp foil & braid, crimp strain relief, then certify to TIA 568B.
16. Do I need special keystone jacks?
For 40 G, yes—Cat 8 metal-body keystones. For ≤10 G, quality Cat 6A shielded keystones work, though full Cat 8 hardware is ideal.
17. Cat 8 vs. fiber—when should I pick copper?
Up to 30 m, Cat 8 is cheaper and easier to terminate than QSFP+ DAC or fiber while re-using RJ-45 switches. Beyond 30 m, fiber wins.
18. Is Cat 8 overkill for gaming and streaming?
If you want absolute future-proofing, yes—and you also get lower crosstalk, potential latency improvements, and multi-gig upgrade room.
19. How well does Cat 8 handle EMI?
The dual-shield design blocks RFI from power cables, fluorescent ballasts, and industrial machinery, keeping NEXT/ANEXT well within spec.
20. What’s the operating temperature range?
-40 °C to +75 °C for bulk solid; patch leads are rated -20 °C – +60 °C.
21. What certifications do Conversions Tech Cat 8 cables carry?
ETL-verified to TIA-568.2-D Cat 8 and ISO/IEC 11801 Class I, plus RoHS and REACH compliant.
22. What warranty is included?
Lifetime performance warranty plus a 30-day money-back guarantee.
23. Which colors and lengths are available?
Patch cords in black, blue, and white from 3 ft to 100 ft; bulk spools (500 ft & 1000 ft) in blue or white. Custom colors on MOQ ≥ 5 km.
24. Can I order custom assemblies or branding?
Absolutely—laser-etched logos, bespoke lengths, and pre-terminated trunks are available with fast lead times.
25. How does Cat 8 pricing compare to Cat 6A?
Typically 1.5 × – 2 × per foot, but you replace four 10 G links with one 40 G run, lowering port counts and switch costs.
