WHAT WE MAKE
One Factory, the Full Cat5e Range
As a cat5e cable supplier, we cover every cord a project can ask for. Standard UTP cords in 24AWG and 26AWG. Shielded F/UTP and STP cords for noisy electrical rooms. Slim 2.8 mm rotatable cords for packed racks. Outdoor Starlink cords with an IP67 seal. Solid or stranded conductors, 0.15 m to 30 m, in ten stock colors. If a build you need is missing from the list, the engineering office prices a custom run in one working day.
Buyers pick this cat5e cable supplier for three reasons: bare copper on every order, a test record on every batch, and one engineer on every file. Cat5e stays the workhorse of LAN cabling, so the factory treats it as a main line, not a leftover run.
- Conductors: 100% bare copper, stranded 7×0.16 mm (24AWG) or 7×0.20 mm, plus 26AWG and 32AWG slim builds. We never quote CCA or CCS.
- Shields: UTP, FTP with foil, F/UTP, and double-shield STP for outdoor Starlink runs.
- Jackets: PVC CMR FT4 riser, LSZH zero-halogen, wear-resistant outdoor PVC, in white RAL9016, grey RAL7042, blue RAL5017, red RAL3020, orange RAL2003, yellow RAL1018 and more.
- Plugs: RJ45 8P8C with 3-prong contacts, 3 to 50 micro-inch gold over nickel, PC 94V-2 housings, molded or snagless boots.
- Performance: 100 MHz bandwidth, Gigabit Ethernet, PoE/PoE+/PoE++ up to 60 W on shielded builds, tested to ISO/IEC 11801 and ANSI/TIA-568-C.2.
Who buys from this cat5e cable supplier
Telecom wholesalers restocking shelves. ISP crews cabling homes. Security teams wiring cameras on PoE. Data center contractors filling dense cabinets. Online brands building retail packs. If you resell or install Ethernet cords, this line was built for you.
Where these cords go to work
Cat5e cords leave our dock for more jobs than most buyers expect. Each scene below maps to a build we already run, so matching your job to a SKU takes minutes, not weeks.
- Office LANs and campus rooms: gray and blue UTP cords in 0.5 m to 5 m, snagless boots for packed patch panels.
- IP camera and CCTV rolls: F/UTP cords that carry PoE++ 60 W to heaters and zoom motors without voltage drop.
- Starlink and RV kits: the outdoor STP cord with an IP67 seal and a 2,000-bend rating for portable dishes.
- Retail and e-commerce packs: ten colors, printed poly bags, header cards and barcodes under your brand.
- ISP home installs: short 0.15 m to 0.3 m cords in bulk cartons that cut truck-stock cost per visit.
- Server rooms and studios: slim 2.8 mm rotatable cords that turn inside packed racks without kinking the jacket.
Tell the cat5e cable supplier which scene matches yours, and the quote comes back grouped by job, not just by SKU, so your crew picks the right box on site.

MOQ drops to 200 pcs per length on trial orders that mix three stock lengths. Rush slots finish stock items in 5–7 days; ask for one when your install date is fixed. Ask this cat5e cable supplier for the live stock matrix before you commit a project date. Custom tooling for boots or colors adds 8–12 days on the first order only.
MATERIAL POLICY
Why Bare Copper Decides the Link
Copper-clad aluminum reads well on a price list and fails in the field. Aluminum carries current poorly, so a CCA cord runs hot on PoE cameras, drops frames on long runs, and can crack at the crimp after a few months on a moving rack. A cat5e cable supplier that mixes CCA into bulk lots counts on you never testing the cords. That is why we state the policy on the page instead of inside a drawer.
Our rule is simpler: annealed bare copper on every SKU, with 4N oxygen-free copper on shielded, outdoor and Starlink builds. Each copper lot arrives with an SGS purity report, and the CNAS lab re-checks resistance before the lot reaches the line. That is the whole trick behind cords that hold Gigabit at 90 meters and pass retest years later.
WHOLESALE TERMS
Volume Tiers and Price Logic
Pricing follows one rule: bigger boxes, lower unit cost. Every tier keeps the same copper, the same plug and the same tests. Some factories swap CCA into bulk orders to cut cost; the loss shows up in your returns. This cat5e cable supplier keeps bare copper in every tier.
- Quotes hold for 30 days, so you can bid on projects without repricing.
- Defect claims stay below 0.3% across three years of shipments.
- One contact engineer follows your order from drawing to container.
- Repeat orders reopen with one email, because your spec sheet stays on file.
OEM · ODM
OEM and ODM Service
Brand the cords as yours. As an OEM cat5e cable supplier, we print logos on boots, bags, boxes and barcodes, and we build new lengths or jacket colors to your drawing. Boot tooling, retail graphics and carton marks all run in-house. The standard path runs in five steps:
- Day 0 — You send lengths, colors, plug style and target price.
- Day 1–2 — We return a spec sheet, a costed quote and a packing plan.
- Day 3–7 — You approve pre-production samples with your logo on them.
- Day 8+ — Mass production runs with 100% wire-map and batch Fluke tests.
- Before ship — You get test reports, photos and a packing list to approve.

180,000 grey cords in 26 days
An ISP needed 0.5 m, 1 m and 2 m UTP cords in RAL7042 grey to match its wall plates. We ran three lengths on two lines, delivered in 26 days, and closed the program with a 0.12% claim rate. Reorders now ship every quarter.
95,000 slim rotatable cords for camera drops
A security distributor wanted short 0.3 m FTP cords that turn inside packed camera housings. We tooled a slim rotatable boot, passed their 48-hour salt-spray check, and shipped 95,000 pieces in 18 days.
60,000 private-label retail packs
An e-commerce brand sold six-length cord kits under its own label. We printed header cards, applied FNSKU barcodes and packed single units, so the goods went straight to their warehouse without rework.
CERTIFICATES
Certifications You Can Put in a Bid
Tenders fail on missing paperwork, so this cat5e cable supplier keeps the file complete. Every certificate below is current and shareable at RFQ stage, and each shipment can carry a batch test report.
Batch documents on request: Fluke channel report, SGS copper-purity report, plug salt-spray report and carton drop-test record.
FACTORY STRENGTH
Inside the Plant Behind Every Cord
COBTEL runs five manufacturing centers across China and opened a Vietnam base in 2025 to shorten sea freight for US buyers. The Dongguan copper plant keeps 36 automated crimping lines, 14 Fluke DSX-8000 testers and 8 plug-injection machines under one roof, with 1,000,000 cords of monthly capacity across Cat5e to Cat8.
Certificates are only half the story. The group holds 265 patents, was named a National High-Tech Enterprise in 2016 and a Specialized Little Giant firm in 2020, and puts 5% of revenue back into R&D. For you that means a cat5e cable supplier with the lab depth to catch a bad plug lot before it ships, and the line capacity to hold a 26-day schedule on 180,000 pieces.
- 36 automated crimping lines run two shifts, six days a week.
- 14 Fluke DSX-8000 units test every batch against TIA channel limits.
- A 20-engineer office turns your drawing into tooling in 8–12 days.
- Vietnam (2025) and five China centers keep freight lanes open in peak season.
- The CNAS L21456 lab audits incoming copper and plugs every lot.
- Two-shift output crossed 1,000,000 cords in one month in late 2025 without weekend runs.
QUALITY CONTROL
Six Checks Before a Carton Seals
Each order passes the same six gates, and the record travels with the goods. This is how the cat5e cable supplier keeps claim rates under 0.3%.
- Incoming lot check — copper purity, jacket OD and plug plating verified against the spec sheet, with SGS reports on file.
- Pull-off test — crimped joints hold 110 N between cable and plug, sampled per line per shift.
- 100% wire map — every cord checked pin-to-pin for opens, shorts and crossed pairs.
- Batch Fluke test — DSX-8000 channel test to ANSI/TIA-568-C.2 on an AQL sample per lot.
- Endurance sample — 750 mating cycles and a 48-hour salt-spray run on outdoor and shielded builds.
- Final pack audit — label scan, carton drop test and photo record before the container seals.
Copies of every gate record stay on file for 24 months, so a claim raised in year two still opens with data, not memory.
TRADE TERMS
Packing, Payment and Shipping
Packing is set up for importers, because a cat5e cable supplier that ships clean cartons saves you rework at the warehouse. Standard packing is one cord per PE bag, 100 bags per inner box, and cartons capped at 12 kg so one worker can lift them. Retail programs upgrade to printed poly bags and header cards at no tooling cost. Cartons carry your SKU code and purchase order number on two sides, so receiving takes minutes. We ship FOB Shenzhen as default, with EXW, DAP and courier DDP on request.
- Payment: T/T 30% deposit and 70% against B/L copy; L/C at sight from USD 50,000; PayPal for sample freight.
- Lead terms: stock items 7–12 days, custom builds 15–25 days, rush slots 5–7 days.
- Documents: commercial invoice, packing list, COC, batch test reports and photos before loading.
- After-sales: a 24-month claim window, video diagnosis within one working day, free replacements with your next shipment.
Safety note: pay only to the beneficiary "Cobtel Precision Electronics Co., Ltd.". We never request crypto wallets or personal accounts, and we confirm every bank-detail change by video call.
PROCESS
From Inquiry to Container in Four Moves
Buyers rarely ask what happens after the deposit, yet that is where schedules slip. Here is the path a cat5e cable supplier should walk you through, and the one we run every week.
- Lock the spec — we confirm lengths, colors, plugs and packing on a one-page sheet that you sign off.
- Reserve the line — your slot is booked on named crimping machines, so rush orders do not bump you.
- Run and test — production flows through the six QC gates, with photos sent at half-run on long orders.
- Load and track — cartons are palletized, photographed and tracked to the port, with the B/L number shared on loading day.
At each move you get a named contact, a date and a record. Projects rarely slip twice when the paper trail is this plain.

FAQ
Frequently Asked Questions
What is your MOQ as a cat5e cable supplier?
Standard cords start at 500 pieces per length and color, and mixed lengths count as one order. Slim rotatable cords and retail packs start at 1,000 pieces. Trial buyers can blend three stock lengths from 200 pieces per length.
Can I get samples before I place an order?
Yes. We send 5–10 stock samples free and you cover the courier, so they reach most countries in 3–5 working days. Custom-spec samples take 7–10 days and the fee returns as credit on your first order.
Do the cords really pass Fluke testing?
Every cord passes a 100% wire-map and continuity check, and each batch is sampled on a Fluke DSX-8000 against ANSI/TIA-568-C.2 channel limits. Short runs use the same unit in patch-cord mode, so the numbers match how the cord behaves in your rack. The batch report ships with the goods, so your customer can read the numbers too.
Is the conductor bare copper or CCA?
100% bare annealed copper, with 4N oxygen-free copper on shielded and outdoor builds. This cat5e cable supplier never quotes CCA or CCS at any price, and an SGS purity report is available for every copper lot.
How fast can you produce my order?
Stock colors and lengths ship in 7–12 days, custom builds in 15–25 days, and rush slots clear stock items in 5–7 days. A named engineer confirms your production slot within 24 hours of the deposit.
Can you print my logo on the cords and packs?
Yes — boots, labels, PE bags, header cards and cartons all take your brand. Logo work starts at 1,000 pieces per SKU, artwork is free, and we sign an NDA when your project needs one.
Which certifications do you hold?
ISO 9001:2015, ISO 14001:2015 and IATF 16949:2016 cover the system; CE, UL, RoHS and REACH cover the product; ETL verification applies to TIA-568.2-D channel performance. Full documents go out with every quotation.
Should I buy UTP or FTP Cat5e cords?
UTP suits offices and homes with normal interference, and it costs less per run. FTP or STP suits industrial floors, broadcast rooms and long PoE runs near power lines. Mixed sites often take UTP for the desks and FTP for the camera run on the same PO. Send your site photos and we will mark the mix per floor at no charge.
Which lengths and colors can I order?
Any length from 0.15 m to 30 m, in ten stock colors including white RAL9016, grey RAL7042, blue RAL5017, red RAL3020, orange RAL2003 and yellow RAL1018. Boot colors can differ from the jacket when your racks use color codes. Lengths print on each boot label when your crew sorts boxes by size.
What are your payment and warranty terms?
We work on T/T 30/70, accept L/C at sight from USD 50,000, and quote FOB Shenzhen by default. The warranty runs 24 months; claims have stayed below 0.3% for three years and replacements ship free with your next order. Samples travel by air courier, and full containers leave Shenzhen twice a week in peak season.

*Note: The dashes (—) indicate where data is not specified. The impedance is given as a range between 85 to 115 ohms for frequencies at 1MHz, reflecting the cables' capability to maintain a consistent impedance across a range of frequencies for optimum signal transmission. NEXT values express how much signal crosstalk is mitigated by the cable design, and attenuation measures the strength of the signal as it travels through the cable at different frequencies. Maximum DC conductor resistance is provided to assess the cable's efficiency in conducting electricity. The table displays the robust performance metrics that are instrumental in ensuring stable and reliable network connectivity for various applications.
