KEY FEATURES & CONSTRUCTION

Stainless Steel Armor Protection: Built with a protective stainless 

steel tube casing to deliver high resistance against crushing, rodents, 

and mechanical stress while preserving physical flexibility.

Bend Insensitive Fiber: Features G.657.A1 fiber standard, allowing tighter 

cable bends with minimal signal loss, fully backward compatible with 

standard G.652.D single-mode fiber systems.

High Precision Connectors: Premium FC and ST connectors with UPC 

ultra-polished ceramic ferrules ensure low insertion loss (≤0.3dB) and high return loss (>50dB).

Riser Rated Outer Jacket: Flame retardant OFCR (Optical Fiber 

Conductive Riser) jacket designed for safe installation in vertical shafts, 

backbones, and building riser spaces.

FC/UPC to ST/UPC Simplex Armored Fiber Patch Cord

A single-fibre assembly that combines a threaded FC/UPC connector with a legacy ST/UPC bayonet connector, built on stainless-steel-armored simplex cable. The armour is the point of this cord: it protects the fibre where the route crosses factory floors, runs through cable trays with other services, or passes anywhere a rodent or a heavy foot can reach it.

Construction & Materials

A single 900 µm tight-buffered fibre sits inside a spiral stainless steel tube, which is then over-jacketed in flame-retardant LSZH or PVC to 3.0 mm. The armour gives crush and bite resistance while keeping the assembly flexible enough for a 40 mm bend radius. OS2 9/125 µm single-mode fibre is used for long-reach and telecom links, and each end is polished to UPC with an FC threaded keyed body at one end and an ST bayonet body at the other.

Key Features

• Spiral stainless steel armour resists crush, rodent attack and abrasion
• Single-mode OS2 fibre supports long-reach and telecom link budgets
• Maintains roughly a 40 mm bend radius despite the armouring
• 100% factory end-face inspection and IL/RL test report supplied with every batch
• Custom lengths, breakout counts, jacket colour and OEM printing available

Typical Applications

• Data centre cross-connects and top-of-rack patching
• Telecom central office and ODF termination
• FTTx access networks and subscriber drop panels
• Industrial and campus backbone cabling where bend loss matters

Specifications

• Insertion loss: ≤0.30 dB (typical), ≤0.50 dB (max) for multimode assemblies
• Return loss: ≥50 dB (UPC), ≥60 dB (APC)
• Operating temperature: −40 °C to +75 °C
• Durability: ≥500 mating cycles to IEC 61300-3-2

Selection Notes

Specify armoured cord wherever the patch route leaves the cabinet. Inside a rack, standard cord is cheaper and easier to dress; the armour only earns its cost on exposed runs. Where the cord will be flexed repeatedly — a test bench or a portable kit — ask for the spiral-armour variant rather than a corrugated tube, because the spiral construction survives repeated bending far better. Confirm the jacket rating for the route: LSZH for indoor public and riser spaces, PVC where only mechanical protection is needed.

FAQ

Can you supply this assembly in custom lengths and colours? Yes. Huifiber builds patch cords to order in any length from 0.5 m to 50 m, with a choice of jacket colour, boot type and printing. Send us the connector pair, fiber type and length and we will confirm the price within 48 hours.

Do you provide test reports? Yes. Every batch ships with insertion loss and return loss test data, and we can supply an interferometric end-face report for single-mode assemblies on request.

What is the minimum order quantity? Standard configurations ship from 100 pieces. Mixed-model orders can be combined to reach the MOQ.
