2F, LC UPC Duplex to LC UPC Duplex, LSZH, OS2, Armored, 3.0mm
The armored fiber patch cable with built-in metal armor can resist mechanical damage from crushing, abrasion, cutting, and pulling in the most hazardous areas. It can protect fibers and prevent network outages. Armor construction eliminates the need for conduit, providing a smaller crush-resistant pathway for improved design flexibility and lower installed cost.

FAQ
Q1. What is an armored fiber patch cable?
An armored fiber patch cable is a fiber optic patch cord reinforced with a stainless steel interlocking armor layer between the inner fiber and the outer jacket. It provides superior crush resistance, rodent protection and tensile strength while keeping the flexibility of a standard patch cord — ideal for industrial, outdoor and data center environments.
Q2. Why choose armored patch cords instead of standard ones?
Armored patch cords offer 3–5x higher crush and tensile resistance than standard PVC patch cords, withstand repeated bending and foot traffic, and protect the fiber from rodents and accidental damage. This reduces maintenance cost and downtime, which is why telecom operators and data center integrators prefer them for permanent links.
Q3. What is the difference between OS2 single mode and OM3/OM4 multimode?
OS2 single-mode fiber (9/125 μm) is designed for long-distance transmission up to 10 km+ and supports higher bandwidth per fiber, while OM3/OM4 multimode (50/125 μm) suits short-reach applications under 300–550 m inside data centers. This OS2 patch cable is the right choice for backbone, campus and carrier-grade networks.
Q4. What is the difference between LC UPC and LC APC connectors?
UPC (Ultra Physical Contact) has a flat polished endface with typical return loss ≥ 50 dB, while APC (Angled Physical Contact) has an 8° angled endface with return loss ≥ 60 dB. This cable uses LC UPC duplex, standard for most switches, patch panels and transceivers — please confirm your equipment connector type before ordering.
Q5. What are the typical insertion loss and return loss values?
Insertion loss is ≤ 0.2 dB and return loss is ≥ 50 dB per connector, meeting or exceeding Telcordia GR-326 and IEC 61753-1 standards. Every cable is 100% factory tested and comes with individual test reports on request.
Q6. Is this cable bend-insensitive?
Yes. It is manufactured with G.657.A2 bend-insensitive fiber, allowing a minimum bend radius of only 7.5 mm (vs. 30 mm for standard G.652.D), making installation in tight spaces, cabinets and corners much easier without signal degradation.
Q7. What does LSZH jacket mean and why is it important?
LSZH (Low Smoke Zero Halogen) jacket emits minimal smoke and no toxic halogen gas when burned, complying with IEC 60332-1 and IEC 60754. It is mandatory in most data centers, telecom rooms, tunnels, ships and public buildings for fire safety and personnel protection.
Q8. Why is the jacket blue?
Blue is the standard TIA-598 color code for single mode (OS2) patch cords, making it easy to distinguish single mode from multimode (aqua/OM3, lime/OM4) during installation and maintenance — reducing human error in large cable runs.
Q9. What is the 3.0 mm cable diameter used for?
The 3.0 mm armored construction balances protection and flexibility. It fits standard LC duplex connectors, works with most patch panels and cable managers, and is suitable for FTTH, FTTA, data center patching, industrial cabinets and outdoor-adjacent runs.
Q10. Do you support custom length?
Yes. We offer custom lengths from 0.5 m to 100 m with ±0.1 m tolerance. Please specify your required length (e.g., 2 m, 5 m, 10 m) when placing a wholesale order — no extra tooling cost for standard custom lengths.
Q11. What is the MOQ for bulk orders?
MOQ is 100 pcs for standard stocked lengths. For custom lengths or OEM orders, MOQ is 200 pcs. We also welcome trial orders to evaluate quality before large-scale procurement.
Q12. What is the lead time for wholesale orders?
Stock items ship within 3–5 working days. Custom length orders take 7–10 working days, and OEM/ODM orders (custom logo, packaging, labels) take 12–15 working days after sample approval. Urgent orders can be arranged with express shipping (DHL/FedEx/UPS).
Q13. Do you provide free samples for testing?
Yes, we provide free samples (1–2 pcs) for qualified B2B buyers; courier cost is on the buyer's side. Samples are shipped within 24 hours and can be tested before you place a bulk order.
Q14. Do you support OEM/ODM service?
Absolutely. We offer OEM/ODM services including custom jacket color, custom logo printing, custom label and barcode, private label packaging, and custom connector polishing (UPC/APC). Your brand, our factory quality.
Q15. How do you pack the cables for export?
Each cable is individually wrapped in PE bag with strain-relief protection, then packed in export-standard cartons with foam cushioning, suitable for sea/air freight. Custom retail packaging and neutral packaging are available on request.
Q16. Do you provide test reports and certifications?
Yes. Every batch ships with 100% insertion loss/return loss test reports. We hold ISO 9001 quality management certification, and products comply with RoHS, CE and Telcordia GR-326 standards. UL certification available for specific product lines.
Q17. What is your warranty policy?
We offer a 3-year warranty against manufacturing defects under normal operating conditions. Defective units will be replaced free of charge or refunded after verification, giving wholesale and distribution partners full confidence.
Q18. Where is this cable typically used?
Typical applications include data center structured cabling, enterprise LAN/MAN backbone, FTTH/FTTB drop cables, 5G fronthaul/backhaul, telecom central offices, industrial automation, security/surveillance systems and harsh environment cabling where standard patch cords fail.
Q19. Can I use this cable outdoors?
The armored layer provides excellent mechanical protection, and combined with a water-blocked design (optional) it can be used in outdoor-adjacent, semi-outdoor or industrial areas. For fully outdoor aerial/underground installation, we recommend our outdoor armored patch cables with water-blocking and UV-resistant jacket.
Q20. What payment methods do you accept?
We accept T/T, PayPal, Western Union, and credit card for trial orders; L/C and T/T for bulk orders. Flexible payment terms can be discussed for long-term cooperation. Our export team provides professional after-sales support in English, Spanish, and Chinese.
