Elfcam Armored OM3 Multimode Duplex Fiber Cable 40m

Elfcam's 40m armored OM3 multimode duplex fiber cable is a shielded LC/UPC-to-LC/UPC patch cord built for indoor and outdoor concealed runs where rodent, abrasion, and crush protection matter.

This rugged 131.2 ft multimode fiber assembly combines a 50/125 μm OM3 core with armored steel tape and a low-smoke zero-halogen (LSZH) jacket to protect high-speed links in industrial, transit, data center, and concealed outdoor environments. Designed for duplex LC/UPC connectors, the cable supports modern short-reach transceivers including 10GBase-SR, 25G SFP28, 40G QSFP+, and 100G QSFP28 while meeting strict insertion- and return-loss specifications. Every cord is tested and certified for consistent performance, giving installers a reinforced option where normal fiber might be too vulnerable.

How does this cable protect fiber in tough installations?

The cable uses a shielded steel tape under the outer jacket to resist cuts, rodent bites, and abrasion, and the LSZH outer layer reduces toxic smoke if exposed to heat. This layered design keeps the glass core mechanically isolated from external forces and moisture when properly routed.

• Armored steel tape beneath the jacket for crush and bite resistance
• LSZH outer sheath for low smoke and halogen-free safety
• 3.0 mm diameter per fiber for easier conduit and tray routing
• Reinforced strain relief at connector interfaces to limit stress

Will this cable meet my network speed and loss requirements?

Yes — the OM3 multimode fiber and precision LC/UPC connectors support 10Gb to 100Gb short-reach transceivers with tight loss numbers. Elfcam certifies insertion loss and return loss to ensure predictable link budgets for typical data center and campus runs.

• OM3 multimode, 50/125 μm core/cladding for 10G–100G short-reach
• Insertion loss ≤ 0.2 dB and return loss ≥ 35 dB as supplied
• Compatible with 10GBase-SR, 25G SFP28, 40G QSFP+, 100G QSFP28
• Duplex LC/UPC connectors for standard multimode ports

Where can I install this armored multimode patch cord?

The cord is intended for concealed outdoor runs and indoor routes that need protection from mechanical hazards. Use it in factory floors, railroad equipment rooms, stadiums, churches, or any location where armoring reduces maintenance risk compared with unarmored fiber.

• Concealed outdoor pathways not continuously exposed to weather
• Industrial environments near machinery or moving parts
• Transit, rail, and campus infrastructure with rodent exposure
• Data closets and patch panels requiring durable jumper runs

How is quality verified and what support is available?

Elfcam performs stress testing and certifies each cable to industry standards to ensure consistent optical performance. The product carries ITU G657A2/B2 compatibility notes and comes with customer support available in the U.S.

• Factory-tested for insertion and return loss consistency
• ITU G657A2/B2 certification mentioned for compatibility
• 24/7 U.S.-based customer service for installation help
• Clear labeling and standard LC/UPC interface for easy plugging

Who is this for: Installers, network engineers, and facilities managers who need a dependable multimode duplex fiber patch cord that resists physical damage while supporting modern multi-gigabit transceivers. It’s best for concealed outdoor runs, industrial sites, transit infrastructure, and any location where an armored, LSZH-jacketed OM3 cable reduces the risk of downtime and costly repairs.
