FIBCONET manufactures fiber optic cable clamps and hardware for aerial FTTH, ADSS long-span, figure-8 self-supporting and drop-cable installations. Combined output on our mainstream plastic clamp lines reaches one million pieces per month, with dedicated stamping and injection tooling supporting fast MOQ from 100 kousky.
Every clamp is tested to IEC 60794-1-2 tensile methodology before shipment, with per-batch tensile strength, appearance and toughness verification. Steel components are available in 201 nebo 304 nerezová ocel, hot-dip galvanized carbon steel, or die-cast aluminum alloy — matched to your climate, span length and service-life target.
Below are the six clamp families currently shipping to telecom operators, FTTH engineering contractors, power utilities and municipal broadband projects across Southeast Asia, na Středním východě, Latin America, Europe and Africa.
| Série | Funkce | Tensile Rating | Typical Application |
|---|---|---|---|
| Plastic Tension / Kotevní svorka (PA6 / PA66) | Terminal anchoring, axial tension load | 600 N – 8 kN | FTTH aerial drop, short-span ADSS, zeď / pole terminal fixation |
| Aluminum Alloy Tension Clamp (Heavy-Duty) ⭐ | Long-span axial tension in harsh outdoor conditions | Až do 10 kN rated | Coastal salt-fog areas, all-optical campus, surveillance backbone, industrial aerial trunk |
| Suspension Clamp (J-Type, Rubber + Galvanized Steel) | Vertical load only — supports cable weight on straight-line poles | Hodnoceno 1.5 kN vertical, break 3.8 kN | Long-span ADSS straight-line suspension, mid-pole fixation on aerial trunk |
| Stainless Steel Drop Wire Clamp (201 / 304) | Terminal anchoring for drop cable and slim ADSS | 600 N – 3 kN (thickness dependent) | pokles FTTH, outdoor terminal, pobřežní / marine deployments (304) |
| Figure-8 Cable Clamp | Grips figure-8 self-supporting cable at its integral messenger | Matched to 2.5 mm galvanized messenger | Obrázek-8 (GYXTC8S) aerial deployments |
| Hardware Accessories | Pole bracket, mounting hoop, bolt-crimp bracket, stainless steel band & buckle | 2.5 kN – 6 kN (bolt bracket); 4 kN (mounting hoop) | Pole fixation, montáž na stěnu, cable routing, band-strap fastening |
Ordinary indoor-grade plastic clamps are strictly not recommended for long-term outdoor aerial installations — they do not meet telecom durability specifications. For any outdoor deployment, choose an outdoor-rated plastic series (UV-additive PA6/PA66), slitina hliníku, or stainless steel from the tables above.
This is the most common source of buyer confusion, so it’s worth being precise:
| Napětí / Kotevní svorka | Suspension Clamp | |
|---|---|---|
| What it does | Holds the full axial tension of the cable — offsets pulling force at the line terminus | Supports the vertical weight of the cable only — does not carry axial tension |
| Where it goes | Line terminals, pole corners, dead-ends, equipment lead-in points | Straight-line poles between terminals, mid-span fixation |
| Load profile | Horizontal pulling force + all axial tension | Vertical load (cable self-weight) pouze |
| Typical tensile rating | 600 N – 10 kN depending on material | 1.5 kN vertical rated / 3.8 kN break strength |
| Pravidlo | Every line-end and every direction change needs one | Use between terminals to prevent cable sag over distance |
Four questions drive the right selection: function, typ kabelu, životní prostředí, a tensile load.
| Typ kabelu | Recommended Clamp Series |
|---|---|
| Přívodní kabel FTTH (motýl / bow-type) | Plastic PA6/PA66 tension clamp, or stainless steel drop wire clamp for coastal use |
| Jednoplášťový ADSS, sahá až do 200 m | Plastic PA6 anchor clamp with SS201 wire (short span); slitina hliníku 10 kN (long span) |
| Dvouplášť ADSS, sahá až do 300 m | Aluminum alloy tension clamp; suspension clamps between terminals |
| Figure-8 self-supporting cable (GYXTC8S) | Figure-8 cable clamp matched to 2.5 mm galvanized messenger |
| Round cable, 2–8 mm diameter | Stainless steel round-cable clamp |
| Byt / kožený kabel, 2×3 mm or 2×5 mm | PA66 nylon flat cable clamp, až do 1,062 N tažné |
| životní prostředí | Doporučený materiál | Expected Service Life |
|---|---|---|
| General outdoor, inland, moderate climate | Outdoor-grade PA6 / PA66 with UV additive | 20+ let |
| Coastal salt-fog, mild marine exposure | Aluminum alloy (trivalent chromium passivation) nebo 304 nerezová ocel | 10–15 years (hliník); 15+ let (SS) |
| Heavy coastal salt spray, offshore | 304 nerezová ocel, hot-dip galvanized suspension body | 15+ let |
| Chemical / industrial atmosphere | 316 stainless steel band & buckle | Application dependent |
| Indoor risers, temporary wiring | Standard plastic clamp acceptable | Application dependent |
Every clamp has a specified cable-diameter range. Common ranges we manufacture: 3–9 mm (plastic tension); 3–10 mm (slitina hliníku); 5–20 mm across A/B/C/D sizes (suspension); 2–8 mm (round steel). Always confirm the exact OD of your target cable before ordering.

MOQ varies by series: 100 kousky for plastic and stainless steel drop-wire clamps; 500 kousky for suspension clamp, wedge-type tension, hardware brackets and hoops; 1 kus for stainless steel band & buckle sample. Custom mold development is available free of charge for qualifying volumes.
Suspension clamp: 10 dní. Plastic drop-wire clamp and stainless steel clamp: typically 10–15 days depending on quantity. Aluminum alloy and custom-colour or custom-mold builds: quoted per project. Regular configurations of common SKUs are held in stock and can ship within days.
Ano. We support laser logo marking on plastic and metal parts, mold-printed logo for high-volume orders, shell colour customization on plastic clamps, and full private-label packaging (logo vnějšího kartonu, nálepky se značkou kupujícího, product-logo printing). Custom mold development is supported and often provided free of charge for qualifying order volumes.
A napětí (anchor) svorka holds the full axial tension of the cable at line terminals, pole corners and lead-in points — it bears the horizontal pulling force. A závěsná svorka only supports the vertical weight of the cable on straight-line poles between terminals — it does not carry axial tension. Every line-end needs tension clamps; suspension clamps go in between to prevent cable sag.
For heavy salt-spray environments, použití 304 nerezová ocel for all steel components — our 304 grade passes a 96 h neutral salt-spray test with no visible corrosion (exceeding the industry-standard 72 h). Aluminum alloy with trivalent chromium passivation is a strong alternative for the clamp body, delivering 10–15 years of stable service in mild coastal salt fog. Avoid 201 stainless steel and galvanized carbon steel for prolonged coastal use — long-term maintenance cost will exceed the initial price difference.
Ratings by series: 600 N (· Snadná montáž pomocí mechanického spoje a žádné leštění · Minimalizujte počet vad pomocí funkcí odstranění a opětovného použití 0.5 mm stainless steel drop-wire clamp) až do 1,500 N for thicker variants; 1.5 kN – 3 kN for standard plastic tension clamps; 2.5 kN – 6 kN for bolt-crimp bracket family; 4 kN for suspension clamp break strength (rated 1.5 kN vertical); až do 8 kN for PA1500 heavy plastic anchor; až do 10 kN for die-cast aluminum alloy tension clamp; až do 15 kN for hardware series (metal bracket & buckle).
Ne. Our tension clamps use a wedge self-locking + soft-contact protective design that distributes tension evenly over the contact section rather than concentrating pressure on a single point. Suspension clamps use a TPR soft rubber liner + galvanized steel shell composite structure that grips the cable without crushing the jacket or introducing microbend loss to the internal fiber.
Most of our clamp series install by hand without special tools — the wedge self-locking design engages when tension is applied. We provide dedicated installation videos for each series. For safety we recommend wearing gloves when handling stainless steel edges. Bolt-crimp brackets use standard M4/M5/M6 hex bolts compatible with common wrenches.
Životnost designu: 20 let for UV-additive plastic clamps; 25 let for aluminum alloy and suspension clamps; 15 let in coastal salt-spray areas for hot-dip galvanized suspension clamps; 10 years+ for stainless steel drop-wire clamps in general outdoor use. Standard indoor plastic clamps are not suitable for long-term outdoor aerial installations.
Ano. Free single-piece samples are available on most SKUs including PA6 tension clamps. Free samples up to 5 kousky on the stainless steel round-cable clamp. Buyers cover sample shipping cost, which is credited back on the first bulk order. Custom-colour or custom-mold samples are quoted per project.
