FLYPROFiber OS2 LC-LC Single-Mode Duplex Fiber Patch Cable 5m (16ft) 4-Pack — 9/125µm, LSZH, Low Loss

FLYPROFiber's OS2 LC-to-LC 9/125µm single-mode duplex patch cable is a low-loss, flexible fiber cord designed for reliable 1G/10Gb networking in data centers and premise installations.

This 5 meter (16 ft) pack of four LC–LC single-mode duplex cables uses OS2-grade 9/125µm fiber with zirconia ferrule components and LSZH jacketing to deliver consistent low insertion loss and high return loss in indoor environments. Built for tight routing and high-density racks, these cords balance mechanical flexibility with predictable optical performance, and they are factory-tested to meet insertion loss specifications.

How does this cable perform in high-density racks and tight bends?

The FLYPROFiber OS2 patch cord features a 16 mm minimum bend radius—about four times more flexible than many 50 µm cables—so it resists macro-bending loss in congested trays and SAN cabinets. That flexibility reduces signal degradation where cables need to fold sharply or pass through crowded cable managers.

• 16 mm minimum bend radius for tight routing without added loss
• LSZH jacket for safer indoor installations in confined spaces
• Duplex LC connectors for compact pairwise connections in high-density panels

What optical specifications and compatibility can I expect?

These single-mode OS2 cords use 9/125µm fiber with zirconia ferrules to ensure stable, low-loss transmission. Typical insertion loss is ≤0.3 dB and return loss is ≥50 dB, making the cables suitable for Fast Ethernet, Gigabit, and 10 Gigabit links across LANs, data centers, and long-reach premise runs.

• OS2 single-mode 9/125µm for long-distance or high-speed links
• Insertion loss ≤0.3 dB; return loss ≥50 dB for clean signal integrity
• Standard LC duplex connectors compatible with common transceivers and patch panels

Are these cables durable and easy to terminate or service?

The cable core uses high-purity zirconia materials for consistent ferrule geometry and reliable mating. The jacket and fiber construction are optimized for indoor use, with easy stripping and welding during assembly or repair, and temperature tolerance suitable for most network environments.

• Japan-import zirconia powder ceramics in ferrules for stable return loss
• Rated operating range −20°C to +70°C for typical indoor deployments
• LSZH outer jacket minimizes smoke and toxic gas in enclosed spaces

How is quality assured and what support does FLYPROFiber offer?

Each cable is factory-tested for insertion loss and performance to meet quality control benchmarks. FLYPROFiber has 15 years of fiber optic experience and provides customer support for compatibility or troubleshooting questions.

• Factory-tested units to validate optical performance before shipping
• 4-pack convenience for multi-port installations or spares
• Customer service available for product questions and returns

Who is this for: Network engineers, data center technicians, and IT teams who need compact, low-loss single-mode patch cords for high-density racks, SAN cabinets, or premise backbone links will find these FLYPROFiber LC–LC OS2 cables suitable. They are ideal when tight bend routing, predictable optical metrics, and LSZH indoor safety are priorities. If you require longer lengths, multiple connector types, or multimode alternatives, FLYPROFiber also offers additional configurations to match specific installation needs.
