FLYPROFiber OS2 LC‑LC 5m Singlemode Duplex Fiber Patch Cable

FLYPROFiber 5M OS2 LC-to-LC singlemode duplex patch cable is a low-loss, flexible 9/125µm fiber cord designed for 1G/10G networking and dense rack installations.

This LC–LC OS2 patch cord delivers stable singlemode transmission with precision zirconia ferrules, low insertion loss and LSZH jacket for indoor use. It’s engineered for data centers, telecom closets and premise wiring where space is tight and reliability matters. The 5 meter (16 ft) length in this listing comes as a convenient two-pack, and multiple length options are available from 0.2 m up to 300 m to suit different installation needs.

How does this cable reduce signal loss in singlemode links?

The FLYPROFiber OS2 cable uses a 9/125µm core and high-quality zirconia ferrules to minimize insertion and return loss. Factory testing ensures each cord meets tight optical specifications so links remain efficient over longer runs.

• Insertion loss ≤ 0.3 dB for each connector end
• Return loss ≥ 50 dB for stable reflections control
• OS2 grade singlemode fiber for low attenuation across long distances
• Precision polishing and factory-tested connectors

Will this cable survive tight bend routing in racks and panels?

Yes — the cord supports a 16 mm minimum bend radius, giving it roughly four times the flexibility of many 50 µm fibers without adding macrobend attenuation. That makes it practical for high-density panels and tight cable management scenarios.

• 16 mm minimum bend radius for sharp turns
• Thin, flexible construction for crowded trays and patch panels
• Reliable performance in angled or looped layouts
• Durable for repeated routing and adjustments

Is this cable compatible with my equipment and environment?

The LC-to-LC duplex configuration fits standard LC ports used in most switches, SFP transceivers and optical appliances. The LSZH outer jacket and rated operating range make it suitable for indoor telecom rooms and data center environments.

• Standard LC duplex connectors for broad compatibility
• LSZH jacket reduces harmful smoke in enclosed spaces
• Operating range −20°C to +70°C for typical indoor conditions
• Works with Gigabit Ethernet, Fiber Channel, SAN, WAN and more

What quality controls and support come with the cable?

FLYPROFiber performs factory testing on each cable to verify insertion loss and return loss targets. The brand has extensive experience in fiber optics and offers customer support for installation questions or product concerns.

• Factory-tested optical performance per unit
• 15 years of fiber-optics manufacturing expertise
• Accessible customer support for troubleshooting
• Available in many lengths from 0.2 m to 300 m
