Overview of armored single-mode fiber jumper products

The single-mode armored jumper is a fiber optic jumper designed for complex or harsh environments. Its structure adds a metal armored layer (usually stainless steel or aluminum alloy) to the traditional single-mode fiber jumper to provide additional mechanical protection and anti-interference ability. This product is suitable for long-distance, high-bandwidth optical signal transmission scenarios, such as data centers, industrial automation, military communications, outdoor wiring, etc., especially in environments where stretching, extrusion, electromagnetic interference (EMI) or chemical corrosion are required.

Second, the core characteristics of armored single-mode fiber patch cords

1. structural composition
   • Fiber Type: Using single-mode fiber (G.652D or G.657A/B), it supports 1310nm/1550nm wavelengths and is suitable for long-distance transmission (usually 10-100 kilometers).
   • Armor layer: Metal braid or metal tube wraps the fiber to provide tensile (> 50N), compression (> 1000N/10cm) and flame retardant protection.
   • sheath materialThe outer layer is made of low-smoke halogen-free (LSZH) or flame-retardant polyvinyl chloride (PVC) materials, which meet environmental protection and fire protection standards.
2. High performance parameters of armored single mode fiber patch cords
   • insertion loss: ≤ 0.3dB (typical value).
   • return loss: ≥ 50dB (APC connector) or ≥ 45dB (PC connector).
   • Temperature range-40 ° C to + 85 ° C, suitable for extreme climate.
   • bending radiusStatic ≥ 30mm, dynamic ≥ 60mm (armor layer enhances bending resistance).
3. Connector type
   • Support FC, SC, LC, ST and other standard interfaces, optional simplex or duplex design.
   • Connector material: ceramic ferrule (low loss) or metal ferrule (high durability).
4. application scenario
   • Industrial environmentFactory automation, oil/gas platforms, rail transit signaling.
   • Outdoor wiringBase station connection, FTTH (fiber-to-the-home) access, security monitoring.
   • Data Center: High-bandwidth connectivity between racks, replacing traditional copper cables that are susceptible to interference.
   • Military/AviationLightweight design (some models comply with MIL-STD standards).
5. Advantage summary
   • High mechanical strengthThe armor layer resists the biting and accidental pulling of rodents.
   • Strong anti-interferenceThe shielding layer effectively isolates electromagnetic interference (EMI) and radio frequency interference (RFI).
   • Flexible deploymentSupport pre-termination or on-site assembly to meet complex wiring requirements.
   • long durabilityMetal protection extends service life and reduces maintenance costs.

IV. Precautions for the purchase of armored single-mode fiber optic jumpers

1. Confirm the fiber typeMake sure it matches the single-mode specifications of existing network devices, such as OS1/OS2.
2. Armor layer materialStainless steel (corrosion resistant) or aluminum alloy (lightweight) depending on the environment.
3. certification standard: Check whether it meets RoHS, CE, UL and other environmental protection and safety certifications.
4. Connector polishing typeAPC (inclined plane) reduces return loss, suitable for DWDM systems; PC (plane) costs are lower.

V. Examples of typical application scenarios

• Industrial AutomationRobot vision systems and sensor networks for long-distance data transmission.
• FTTH entryReplace traditional leather cable to resist outdoor construction or animal damage.

• Military communicationsAnti-jamming connection between vehicle/shipboard equipment.
