Elfcam Armored OM3 20m LC/UPC Duplex Fiber Cable

Elfcam's 20m armored OM3 multimode duplex fiber patch cable is a shielded LC/UPC-to-LC/UPC link built for indoor and outdoor concealed installations where extra mechanical protection and low-smoke zero-halogen safety are required.

This Elfcam fiber optic patch cord combines OM3 multimode 50/125μm performance with a steel-armored sheath and LSZH outer jacket to deliver a durable 20-meter (65.6 ft) duplex connection. It is engineered for environments where cables face abrasion, crush, tension or rodent exposure yet must also meet fire-safety requirements. The assembly is factory-tested to industry loss and return-loss standards and is compatible with modern short-range multimode transceivers used in 10G, 25G, 40G and 100G links.

How does this cable survive harsh environments?

The cable uses an internal shield of steel tape wrapped under an LSZH jacket, providing mechanical resistance to cuts, bites and compressive force while minimizing toxic smoke in case of fire. The armored core preserves the fiber geometry so optical performance remains stable under stress.

• Reinforced steel tape shielding under the outer jacket for rodent and abrasion resistance.
• LSZH (low smoke zero halogen) outer sheath for safer indoor use in confined spaces.
• 3.0 mm nominal diameter per fiber to balance flexibility and protection.
• Designed for concealed outdoor runs where the cable is not continuously exposed to weather.

Will it work with my 10G / 25G / 40G / 100G equipment?

Yes — this OM3 multimode duplex cable is matched to LC/UPC connectors and multimode transceiver types commonly used for short-range high-speed links. Specified insertion and return loss figures ensure reliable connectivity with SFP+, SFP28, QSFP+ and QSFP28 modules.

• Connector pair: LC/UPC to LC/UPC duplex for standard multimode ports.
• Fiber type: OM3 multimode 50/125μm suitable for 10GBase-SR and higher short-range optics.
• Insertion loss ≤ 0.2 dB and return loss ≥ 35 dB for consistent optical margins.
• Works with 10GBase-SR, 10GBase-LRM, 25G SFP28, 40G QSFP+, 100G QSFP28 transceivers.

How is this cable tested and supported?

Elfcam subjects each patch cord to factory testing and certification to confirm optical loss and mechanical integrity. The cable family meets ITU recommendations for bending and attenuation performance and comes with a clear warranty and customer service access.

• Stress-tested and factory certified for insertion loss and return loss.
• ITU G657A2/B2 compatibility noted for bend-insensitive characteristics.
• 10-year limited warranty and 24/7 US-based customer support for troubleshooting.
• Clear spec: 20 meters (65.6 ft) length, 50/125μm multimode core.

How should I install and where is this cable best used?

This armored multimode patch cord is suited for concealed outdoor runs, industrial facilities, and indoor spaces that require fire-safe cabling. Avoid continuous direct UV and prolonged submersion; use conduits or protected pathways for outdoor exposure.

• Ideal for concealed outdoor installations, machinery rooms, factories, rail yards, churches and commercial buildings.
• Not intended for continuous direct burial or permanent direct sunlight without conduit protection.
• Works well in rack-to-equipment or short-distance backbone fiber runs up to the limits of OM3 optics.
• Inspect connectors and maintain gentle bend radii during routing to preserve performance.

Who this cable is for: IT professionals, network installers and facilities managers who need a short multimode fiber link with enhanced mechanical protection and low-smoke safety. Choose this Elfcam 20m armored OM3 duplex patch cord when you must balance high-speed multimode connectivity with resistance to physical damage and strict building-safety requirements.
