YUTIANHOME LC-to-LC Armored Single-Mode Duplex Fiber Cable — 165ft/50m, LSZH & Steel Armor

YUTIANHOME's 165ft (50m) LC-to-LC armored single-mode duplex fiber cable delivers a rugged, low-friction outdoor link with OS1/OS2 compatibility for long-distance, high-density installations.

This professional-grade fiber jumper pairs 9/125µm single-mode fiber with a low-friction LSZH jacket and helical steel armor to resist crush and rodent damage while keeping signal loss low. Factory-terminated with precision ceramic ferrule LC connectors and supplied with an LC coupler, it’s built to simplify outdoor runs, duct pulls, and tight-path installations where space, durability, and low insertion loss matter.

How does this cable survive outdoor and high-traffic conduits?

The cable combines a flame-retardant LSZH outer jacket with a helical steel armor layer that shields the glass fiber from mechanical hazards and pests. The armor increases crush resistance without making the cable too stiff for routing through conduit or trays.

• Helical steel armor for crush and rodent protection
• Ultra-low-friction LSZH jacket (μ < 0.2) for easier pulls
• 3.0mm overall diameter balances protection and flexibility
• Min. bend radius at fiber core: 7.5mm for tight routing

What optical performance and connector quality should I expect?

This is a single-mode (9/125µm) duplex cable designed for OS1/OS2 systems, terminated with Foxconn-style ceramic ferrule LC connectors for consistent low insertion loss and repeatable connections. It supports long-reach links typical of campus, metropolitan, or interbuildings fiber runs where single-mode is required.

• Single-mode 9/125µm fiber suitable for long-distance links
• Duplex LC-to-LC termination for quick plug-and-play connections
• Ceramic ferrules for stable, low-loss mating
• Includes LC single-mode adapter for straightforward extension

How easy is installation and management in cramped spaces?

The ultra-low-friction LSZH jacket reduces pull tension and snagging in conduit, making long pulls and dense cable runs faster and less risky. At 3.0mm diameter and a small core bend radius, it fits neatly in patch panels and tight raceways without compromising fiber bend tolerance.

• Low coefficient of friction (μ < 0.2) for smooth duct pulls
• Thin 3.0mm profile for high-density panel installations
• 7.5mm minimum bend radius at the fiber core for tight routing
• Pre-terminated LC connectors minimize field termination work

What maintenance, compatibility, and safety considerations should I know?

The LSZH jacket reduces toxic fumes during fire scenarios and meets common safety expectations for indoor-to-outdoor transition points. The cable is compatible with OS1/OS2 single-mode networks and works with standard LC patch panels, adapters, and transceivers designed for single-mode duplex LC connections.

• LSZH outer jacket for reduced smoke and halogen emissions
• OS1/OS2 compatible with single-mode equipment and transceivers
• Supplied LC adapter included for temporary or extended joins
• Routine visual inspection recommended for armored cable integrity

Who this product is for: Network and infrastructure professionals, integrators, and installers who need a durable single-mode duplex jumper for outdoor-to-indoor transitions, conduit and duct pulls, or any environment where crush and rodent protection plus low-friction installation are priorities. It’s well suited for campus backbones, fiber-to-building runs, telecom cabinets, and any project requiring factory-terminated LC connections with OS1/OS2 compatibility.
