FLYPROFiber LC to LC OS2 Single-Mode Patch Cable 3m 4pk

FLYPROFiber LC-to-LC OS2 single-mode duplex patch cords deliver low-loss, bend-tolerant 9/125µm fiber connections for 1G and 10G networks in a compact, LSZH-sheathed 10ft (3m) cable — available in many lengths and sold here as a 4-pack.

These patch cables use OS2-rated 9/125µm single-mode fiber with precision zirconia ceramic ferrules to keep insertion loss low and return loss high. The low-smoke, zero-halogen (LSZH) jacket is intended for indoor installations where reduced toxic fumes are preferred. With a small bend radius and duplex LC connectors, the cords suit dense racks, SAN cabinets, data centers and premise wiring where predictable optical performance and space savings matter.

How does this cable support fast Ethernet and Fiber Channel links?

The OS2 single-mode core and optimized cladding reduce attenuation across long and short runs, keeping signal loss within industry tolerances for 1G and 10G links. Connector polishing and ferrule materials are chosen to maintain low insertion loss and stable return loss under typical conditions.

• Core/cladding: 9/125µm OS2 single-mode fiber for low attenuation
• Insertion loss: ≤0.3 dB per connector for minimal signal drop
• Return loss: ≥50 dB to limit back reflections on sensitive optics
• Compatible with Gigabit Ethernet, 10 Gigabit Ethernet and Fiber Channel

Will the cable survive tight bends in crowded racks?

Yes — the FLYPROFiber patch cord supports a 16 mm minimum bend radius, which is significantly tighter than older 50 µm designs. This flexibility reduces macro-bending loss when routing through high-density cable managers or around tray corners.

• Minimum bend radius: 16 mm for tight routing without added loss
• Jacket: LSZH for safer indoor environments in confined spaces
• Duplex LC form factor minimizes connector footprint in panels

What length and packaging choices are available for installations?

FLYPROFiber offers a wide range of lengths from 0.2 m up to 300 m to match patching, backbone or campus needs. The listing here is a 3 m (10 ft) cable sold as a 4-pack, which is ideal for small racks, lab benches and office cross-connects.

• Length options: 0.2 m to 300 m to suit patching and permanent links
• Pack configuration: 4-pack of 3 m (10 ft) cables for multiple connections
• Connector type: LC to LC duplex — ready for standard LC ports

How are these cables tested and what quality assurances exist?

Each cable is factory-tested for insertion loss and basic continuity to meet quality control standards. FLYPROFiber uses imported zirconia ferrule materials and controlled assembly to deliver consistent return loss and attenuation across units.

• Factory-tested for insertion loss and optical continuity
• Zirconia ferrules for stable alignment and repeatable connections
• 15 years of company experience in fiber optics and customer support

Who this product is for: Networking engineers, data center technicians, IT managers and integrators who need dependable single-mode LC-to-LC patching in compact spaces will appreciate this FLYPROFiber OS2 duplex cable. It fits scenarios that require low insertion loss, high return loss, tight bend routing and LSZH jackets for indoor installations. Choose shorter lengths for patch panels and 3 m increments for equipment interconnects, or order longer runs for direct links within campus or building backbones.
