FAQ
1. What is an armored fiber patch cable and why do I need it?
An armored fiber patch cable embeds a stainless steel interlocking armor layer between the fiber core and the outer jacket. It protects the fibers from crush, impact, bending stress, and rodent damage, making it ideal for exposed cable trays, under-floor routing, and harsh data center environments — while the 3.0mm diameter keeps it flexible and easy to route. It is a popular wholesale item for data center and FTTA projects that require extra durability.
2. What are the key specifications of this cable?
This is an OM4 duplex 2-fiber patch cable terminated with LC UPC to LC UPC connectors, 3.0mm outer diameter, Riser OFCR fire-rated jacket, in standard Aqua color. It supports 10G, 40G, and 100G Ethernet applications and is fully compliant with TIA-492AAAD and IEC 60793-2-10 standards. A full datasheet and specification sheet is available upon request for your evaluation.
3. Why choose OM4 instead of OM3?
OM4 provides a higher effective modal bandwidth (EMB ≥ 4700 MHz·km at 850nm) than OM3 (2000 MHz·km), enabling longer link distances: up to 550m for 10GBASE-SR and 150m for 100G QSFP28 SR4, compared to 300m and 100m for OM3. For data center bulk orders, OM4 offers better value for money and longer upgrade runway for 400G-ready infrastructure.
4. What does the OFCR (Riser) fire rating mean?
OFCR stands for Optical Fiber Conductive Riser, certified under UL 1666 vertical flame test. It is flame-retardant and low-smoke, suitable for vertical riser runs between floors and general building areas. If your project requires installation in air-handling plenums, we also offer the OFNP plenum-rated version — please specify at the time of your inquiry.
5. What are the insertion loss and return loss performance?
Each cable is tested with typical insertion loss ≤ 0.3dB per connector pair (premium grade ≤ 0.2dB available) and return loss ≥ 50dB for UPC polish. Every unit is 100% tested before shipment, and individual test reports can be provided for quality assurance and project acceptance.
6. How much mechanical protection does the armor provide?
The interlocking steel armor significantly increases crush resistance and tensile strength compared to standard patch cords, while the Kevlar reinforcement provides additional pull strength. This makes the cable suitable for heavy-traffic data center pathways, industrial cabinets, and outdoor-to-indoor transitions — a key selling point for resellers targeting enterprise and telecom projects.
7. Is this cable compatible with my existing data center equipment?
Yes. The standard LC duplex interface is compatible with SFP+ 10G SR, QSFP+/QSFP28 40G/100G SR4 transceivers (via MPO breakout or direct duplex connections), storage area networks (SAN), and switches from major brands such as Cisco, Arista, Juniper, HPE, and Dell. It is the most widely deployed interface in modern data centers, which lowers your inventory risk.
8. What lengths and configurations can I order?
We support custom lengths from 0.5m to 100m+, as well as custom connector types (SC/FC/ST, UPC/APC), simplex/duplex, 2–24 fiber counts, and custom OD (2.0/3.0/4.5mm). OEM/ODM customization — including color coding, boot style, and laser engraving — is available to match your project specifications.
9. Why is the Aqua color used, and can I change it?
Aqua is the TIA-598-C standard color for OM3/OM4 multimode cabling, which helps technicians identify fiber type at a glance and reduces installation errors in large-scale projects. Custom jacket colors are available for branding purposes on bulk orders.
10. How should I store and handle armored patch cables?
Cables should be stored in a dry, temperature-controlled environment (recommended -20°C to +70°C operating range) and routed with a minimum bend radius of 20mm to preserve optical performance. Proper handling instructions and installation guidelines are included with every shipment to minimize field failures.
11. What is the MOQ for this product?
Our MOQ is flexible: trial orders start from 100 pieces so you can validate quality and performance first, while wholesale and bulk pricing applies to orders of 1,000+ pieces. We work with distributors, resellers, and system integrators on long-term supply agreements.
12. Do you support OEM/ODM and private label?
Yes. We offer full OEM/ODM services: custom logo printing, laser engraving, custom labels, custom packaging, and private label options with your own brand or a neutral design. Just share your artwork and specifications, and our engineering team will handle the rest.
13. Can I customize length, jacket material, and connector polish?
Absolutely. You can customize cable length, jacket material (PVC / LSZH / OFNP plenum), outer diameter, connector type and polish (UPC/APC), and packaging. For bulk orders, we recommend confirming all custom specifications in the PI (Proforma Invoice) before production to avoid rework.
14. What is your lead time?
Sample lead time is 3–5 working days; production lead time for bulk orders is 7–15 working days depending on quantity and configuration. Urgent orders can be prioritized — please indicate your deadline in your inquiry so we can arrange the production schedule accordingly.
15. How does KEXINT ensure product quality?
We are an ISO 9001-certified factory. Every cable undergoes 100% insertion loss and return loss testing, visual inspection, and dimensional checks before packaging. We also offer batch traceability and can provide test reports, QC inspection reports, and third-party inspection support for your quality assurance program.
16. What certifications do your cables hold?
Our cables are certified with UL (OFCR riser rating), RoHS, REACH, and CE, and our factory is ISO 9001 certified. Certificate copies are available for your compliance review and project bidding documentation.
17. What are your shipping and trade terms?
We support EXW, FOB (Shenzhen/Ningbo/Shanghai), CIF, and DDP trade terms. Small orders ship via DHL / FedEx / UPS express; bulk orders ship by air freight or sea freight with export-standard packaging. We can also handle consolidated shipping for multi-item orders to save your logistics costs.
18. What payment terms do you accept?
We accept T/T (30% deposit + 70% balance before shipment), L/C at sight, PayPal, and Alibaba.com Trade Assurance online payment. Flexible payment terms can be negotiated for long-term partners and repeat bulk buyers.
19. Do you provide free samples before placing a bulk order?
Yes. We provide 1–2 pieces of free samples for evaluation; the buyer pays the express freight (or we can negotiate a shared arrangement). Samples are shipped within 3–5 working days, and the sample cost can be refunded against your first bulk order.
20. What warranty and after-sales service do you offer?
We offer a 12–24 month warranty against manufacturing defects, plus after-sales technical support from dedicated sales engineers. If a quality issue occurs, we provide replacement or repair per our warranty policy, and we support drop-shipping arrangements for overseas distributors. Your long-term business is our priority.
