FLYPROFiber LC to LC OS2 50m Single-Mode Duplex Cable

The FLYPROFiber LC to LC OS2 single‑mode duplex patch cable is a 9/125µm, LSZH fiber cord built for low-loss, high-density single‑mode networks and comes in flexible length options including 50m.

This cable is designed for modern data center, telecom, and enterprise environments that require single‑mode performance with tight bend tolerance and predictable attenuation. Constructed with high‑precision zirconia ferrules and OS2 9/125µm fiber, the cable supports 1G and 10Gbps links while meeting industry return‑loss and insertion‑loss expectations for reliable optical connections indoors.

How does this cable keep loss and reflections low?

FLYPROFiber uses OS2 single‑mode fiber with a 9/125µm core/cladding configuration and precision‑polished zirconia ferrules to minimize signal loss and back reflections. Factory testing verifies insertion loss and return loss so you install with confidence.

• Insertion loss ≤ 0.3 dB per connector pair.
• Return loss ≥ 50 dB thanks to high‑quality ferrules and endface polishing.
• OS2 fiber specification for long‑reach single‑mode links.
• Factory tested for optical performance before shipping.

Will this cable fit tight racks and many bends?

The cable is engineered with a 16 mm minimum bend radius, offering much greater flexibility than typical 50 µm designs. That makes it suitable for dense patch panels, SAN cabinets and routing through narrow cable management channels without introducing macro‑bending loss.

• 16 mm minimum bend radius for tight routing.
• Duplex LC connectors for high‑density panels.
• LSZH jacket for safer indoor deployments.
• Suitable where multiple bends or limited space exist.

What environments and speeds is this cable made for?

This single‑mode duplex cable supports common network rates including 1G and 10G Ethernet and is appropriate for LAN, WAN, data center and telecom backbone applications. The rated operating temperature range and LSZH jacket make it intended primarily for indoor use where flame‑retardant, low‑smoke materials are preferred.

• Compatible with Gigabit and 10 Gigabit networks, Fiber Channel and typical single‑mode equipment.
• Operating temperature: -20°C to +70°C.
• LSZH outer jacket for indoor, low‑smoke installations.
• Available in many lengths (0.2 m up to 300 m) — this listing is for 50 m length.

How reliable and supported is the product?

FLYPROFiber has 15 years’ focus on fiber optic components and carries out factory testing for each cable to confirm insertion loss and overall quality. The company provides customer support for installation questions or compatibility guidance.

• Each unit factory‑tested for insertion loss and quality control.
• Customer support team available for technical help.
• Manufactured using Japan‑imported zirconia powder ferrules for stability.
• Designed for consistent, repeatable performance in production environments.

Who is this for: network engineers, data center technicians and IT professionals who need a dependable single‑mode LC‑LC duplex patch cable for indoor backbone, rack‑to‑rack or patch panel connections. If you require low insertion loss, high return loss, improved bend tolerance and a limited‑smoke jacket for enclosed spaces, this FLYPROFiber cable is a practical choice.
