FAQ
1. What is a 2-fiber indoor/outdoor OM4 breakout cable assembly?
It is a duplex fiber optic assembly with 2 OM4 multimode fibers protected in a rugged 2.0mm breakout jacket, terminated with LC, SC, FC, ST connectors or left unterminated. It is designed for both indoor and outdoor installation, ideal for campus networks and building-to-building connections.
2. Can this cable be installed outdoors?
Yes. The 2.0mm breakout cable features an outdoor-grade PE jacket with water-blocking protection, making it suitable for underground conduit installation and entrance facility use while remaining flexible enough for indoor routing.
3. Can I mix connector types on each end?
Absolutely. As a custom fiber optic assembly manufacturer, we can terminate hybrid combinations such as LC to SC, LC to FC, or SC to ST on a single cable per your network requirements.
4. Can the cable be delivered unterminated?
Yes. We supply unterminated 2-fiber breakout cable in bulk rolls or cut lengths for field termination, fusion splicing, or pigtail manufacturing.
5. What is OM4 fiber and what distance does it support?
OM4 is laser-optimized 50/125μm multimode fiber. It supports 550m at 10G, 150m at 40G/100G, and is fully backward compatible with OM3, OM2, and OM1 networks.
6. Where is a breakout cable typically used?
It is commonly used in data centers, campus backbone networks, FTTH distribution, and inter-building links through underground conduits, where a compact 2-fiber cable with individual sub-unit protection is required.
7. Do you support OEM/ODM customization?
Yes, we offer full OEM/ODM service including custom connector combinations, cable lengths, jacket colors, laser printing with your logo, and custom packaging design.
8. What is your MOQ?
Our standard MOQ is 100 pieces for standard configurations. For bulk wholesale orders of custom assemblies, please contact us to discuss volume pricing and lead time.
9. What certifications do you have?
Our factory is ISO 9001 certified, and our products comply with CE, RoHS, and UL requirements. Test reports and certificates are available upon request.
10. How is quality tested before shipment?
Every assembly is 100% tested for insertion loss and return loss with end-face inspection. Final QC includes visual inspection, cable continuity testing, and packaging checks before export.
11. What is your lead time?
Standard stock items ship within 3–5 working days. Custom OEM orders typically take 7–15 working days depending on quantity and connector configuration.
12. What payment terms do you accept?
We accept T/T, L/C, PayPal, and Western Union. For new buyers, 30% deposit and 70% balance before shipment is our standard term.
13. Do you offer free samples?
Yes, samples are available for quality evaluation. Sample cost depends on the configuration; it will be refunded or deducted from your first bulk order.
14. What lengths can you produce?
We can customize any length from 0.5m to 500m or longer per roll. Common stock lengths include 1m, 3m, 5m, 10m, 20m, and 50m.
15. Is this cable suitable for underground conduit installation?
Yes. The outdoor-rated PE jacket and water-blocking design make it ideal for underground conduit links between buildings, while meeting entrance facility installation requirements.
16. What is the operating temperature range?
The cable operates reliably from -40℃ to +85℃, suitable for harsh outdoor environments and temperature-varied installation sites.
17. How is the cable packaged for shipping?
Cables are supplied on spools or reels, wrapped with protective film, packed in export cartons, and palletized for sea, air, or express freight to prevent damage during transit.
18. What connector polishing options are available?
We offer both UPC and APC polishing. OM4 multimode assemblies are typically terminated with UPC polish, while APC is available for single-mode and FTTH applications.
19. Can I get a custom jacket color for color-coding?
Yes. Jacket color can be customized for network identification, with aqua as the standard OM4 color. Custom colors are available for OEM orders.
20. How do I choose the right connector type?
LC is recommended for high-density data center patching, SC for standard enterprise networks, FC for vibration environments, and ST for legacy systems. Our sales engineers can recommend the best termination for your project — send us your requirements for a free consultation.
