100M/328FT Outdoor Armored Fiber Patch Cable (OM3/OM4)
This armored fiber optic cable combines a rugged outdoor-grade TPU jacket with dual armor for enhanced protection against abrasion, UV exposure, and water ingress. It supports direct burial and conduit routing, making it ideal for harsh environments such as desert trails, coastal industrial areas, and rooftop installations. The outer diameter of 5.0 mm provides increased resistance to crushing compared with standard cables, while its Uniboot design simplifies terminations and improves bend performance.
Key features include a stainless steel spiral armor tube and inner glass fiber yarns that deliver robust mechanical protection from rodents and heavy pulling stress. The pre-installed pulling eye on one end enables easier deployment through conduits, manholes, or outdoor trench routes. This design is well-suited for long outdoor runs in campuses, factories, and municipal networks where direct burial is planned.
165ft/50m Armored OM3 Fiber Cable With Pulling Eye
This OM3 duplex fiber patch cable features a tough industrial TPU jacket and a dual-protection scheme combining metal armor with glass fiber yarns. Suitable for direct burial, overhead installation, or routing through conduits, it provides reliable performance in challenging environments such as roadways, snowfields, and construction zones. The pull eye kit installed on one end accelerates pulling operations, helping crews deploy cables across large industrial campuses or outdoor networks.
Designed for outdoor reliability, the jacket resists moisture and temperature variation while maintaining strong tensile strength. The combination of steel armor and internal fibers protects the conductors from rodent intrusion and bending stress, ensuring long-term stability in harsh outdoor settings.
100ft/30m LC to LC Outdoor Armored Simplex (Single-Mode)
This single-mode armored option provides robust protection for indoor-to-outdoor fiber links. The rugged build resists moisture and temperature extremes, making it suitable for direct burial or conduit routing in outdoor installations. Its armored design helps guard against physical damage and rodent interference, providing a reliable backbone for campus networks, utilities, and outdoor data links.
With a pre-installed pulling eye on one end, deployment through conduits or manholes is simplified, reducing installation time and risk of fiber damage during pulling. This makes it a practical choice for long outdoor runs where care and efficiency are prioritized.
30Meters/100Feet LC to LC Simplex (Single-Mode)
This 30-meter SC-to-SC fiber patch cord is designed for outdoor, armored, simplex connections. The single-mode construction supports long-reach links with low attenuation, while the armored jacket protects against environmental threats and mechanical damage. An ideal option for outdoor backbone links or campus networks requiring durable outdoor cabling.
Its SC-to-SC configuration supports typical data-center to field deployments, with the protective armor providing improved resistance to bending, moisture, and impact. The product is suitable for installations where longer pull lengths and safe crossing through harsh environments are expected.
10Gtek OM3 Patch Cable LC to LC
This OC-graded OM3 patch cable offers a versatile solution for SFP transceiver deployments and other multi-mode links. It is designed for reliability in data-center corridors, outdoor equipment housings, and field installations where durability and consistent performance are required. The LC-to-LC duplex configuration supports quick terminations and straightforward testing.
With a focus on practical outdoor use, the cable’s armor and jacket composition provide protection against environmental stress while maintaining good optical performance. The patch cable is suitable for short to medium runs in both indoor-outdoor scenarios, contributing to flexible network layouts in mixed environments.
Buying Guide: Key Purchase Considerations
- Armor And Jacket: For underground or outdoor use, prioritize armored designs and rugged jackets (TPU or steel armor) to resist moisture, UV exposure, abrasion, and rodent damage.
- Direct Burial And Conduits: Confirm direct burial compatibility or conduit routing capabilities. Pre-installed pulling eyes and pulling hardware speed up installation and reduce fiber damage risk.
- Fiber Type and Bandwidth: Choose OM3/OM4 for multimode high-bandwidth links, or single-mode 9/125 for long-distance and high-stability connections. Match to your transceiver and link budget.
- Temperature And Weather Resistance: Look for products rated for wide temperature ranges and harsh environments common in outdoor sites, deserts, or coastal zones.
- Installation Flexibility: Uniboot designs, eyelets, and modular terminations simplify field deployment and future upgrades without reworking existing runs.
- Lengths And Pulling Ease: Select lengths that align with route planning; consider cables with pre-installed pulling eyes or easy pull features for long spans.
- Compliance And Certification: Ensure the cable meets relevant industry standards and certifications for outdoor telecom and data networks in the United States.
- Maintenance And Longevity: Armor and jacket materials should minimize sunlight exposure damage and chemical interactions in industrial sites and road corridors.
- Cost vs. Longevity: While armored outdoor cables may cost more upfront, their durability often reduces maintenance and replacement costs over time.
