Customized 4-Fiber OM5 Multimode LC/SC/FC/ST/LSH/Unterminated Indoor Tight-Buffered Multi-Fiber Breakout Cable
Indoor multi-fiber breakout cable is a low-cost cable designed primarily for indoor interconnection between transmission equipment and patch panels or similar fixed routes. Designed with carrier-grade quality, this cable features superior assemblies that minimize light loss during bending for reliable transmission in tight spaces. The fiber optic cable has industry standard flammability rating jacket and the connector meets EIA/TIA 604-2 for high-speed cabling networks.

Features
Carrier-grade Cable with Guaranteed Quality
Superior cable assemblies reduce light loss during cable bending and easily meet your diverse cabling requirements.

Three Jacket Materials Used in Diverse Cabling Zone
It's important to know the differences between Plenum (OFNP), Riser (OFNR), LSZH jackets because each different type is used in different locations.

Breakout Types for Optimizing Cable Routing
Four different breakout configurations meet your various needs.Please note that the breakout length is 0.3m by default instead of 0.5m when the total cable length is not more than 3m.

Two Cable Diameters for Different Wiring Needs
The slim and robust indoor multi-fiber patch cable is not only used for cabling in high-density data centers
but also terminated into rack-mount and wall-mount enclosures.

Precautions for Use
Be sure to read the instruction manual before using this product.
FAQ
1. Q: What is OM5 fiber?
A: OM5 (WBMMF — Wideband Multimode Fiber) is a 50/125 µm multimode fiber optimized for Short Wavelength Division Multiplexing (SWDM). It supports 40G/100G/200G/400G transmission over fewer fibers and is fully backward compatible with OM3/OM4 networks.
2. Q: What is the difference between OM3, OM4, and OM5?
A: OM3/OM4 operate at the 850 nm wavelength only, while OM5 also supports 850–953 nm, enabling SWDM4 to carry 4 wavelengths on one fiber. OM5 delivers the highest bandwidth per fiber — ideal for future high-speed data center upgrades.
3. Q: What does "unterminated" mean?
A: Unterminated means the cable is supplied with bare, stripped fiber ends without connectors — ready for field termination, splicing, or your own connector installation.
4. Q: Which connectors are available?
A: LC, SC, FC, and ST, with UPC or APC polish. All connectors meet EIA/TIA 604-2 for high-speed cabling networks.
5. Q: What is the LSZH jacket?
A: LSZH (Low Smoke Zero Halogen) jacket emits minimal smoke and no toxic halogen gas in a fire, making it the recommended choice for indoor and public-area installations. It is flame-retardant per IEC 60332.
6. Q: Can the cable be customized?
A: Yes — fiber count, length, jacket color, connector type/polish, polarity (A/B), and packaging can all be customized. Samples are available for approval before mass production.
7. Q: What are the typical optical performance values?
A: Insertion loss ≤ 0.3 dB (0.2 dB typical); return loss ≥ 30 dB (UPC). Every assembly is 100% tested before shipment.
8. Q: What is the MOQ and lead time?
A: No strict MOQ — sample orders are welcome. Standard lead time is 3–7 days for stock lengths, and 7–15 days for large custom orders.
9. Q: Where is this cable typically used?
A: Data center high-speed links (40G–400G), LAN backbone, and indoor interconnection between transmission equipment and patch panels or similar fixed routes.
10. Q: Do you provide test reports and warranty?
A: Yes. 100% optical testing (insertion loss, return loss, continuity) with test reports included, plus a 1–3-year warranty and technical support.
