FLYPROFiber LC-to-LC OS2 Single-Mode Patch Cables 4M 6-Pack, Yellow LSZH Duplex, Low-Loss for 10G+

FLYPROFiber 4M LC-to-LC OS2 single-mode duplex patch cables (6-pack) are yellow, 9/125µm jumper cords designed for reliable long-distance fiber connections in data centers and network racks.

These six LC–LC single-mode patch cords from FLYPROFiber are engineered for high-density network environments where stable, low-loss optical links matter. Each 4-meter cable uses OS2 9/125µm fiber with UPC-polished zirconia ferrules and an LSZH jacket to balance performance, safety, and flexibility. Built for 10G and higher applications, the cables include duplex clips, clear polarity labeling, and dust caps to streamline installation and maintenance.

How does this cable perform for high-speed network links?

The FLYPROFiber OS2 single-mode design supports high-bandwidth transmission with low insertion and high return loss, keeping signal integrity across longer runs. UPC-polished ferrules provide precise core alignment that reduces attenuation and reflections.

• Low insertion loss: ≤0.3 dB per connector
• High return loss: ≥30 dB for stable links
• Supports 10G Ethernet and beyond with appropriate transceivers

What installation benefits does the cable offer in dense racks?

These 4m duplex cables are built to bend and route in tight spaces without compromising performance. A 16mm minimum bend radius gives flexibility in crowded cabinets, while clear A/B markings and removable dust caps speed up setup and troubleshooting.

• 16mm minimum bend radius for tight routing
• Embossed A/B duplex clips and jacket tags for polarity identification
• Removable dust caps protect connectors during install

Is this cable safe and durable for commercial and indoor use?

The jacket is Low Smoke Zero Halogen (LSZH), reducing hazardous fumes in enclosed spaces and complying with modern safety preferences. Temperature-rated construction allows use in typical telecom and premise environments without performance loss.

• LSZH outer jacket reduces smoke and toxic gas if heated
• Operational temperature range: −20 °C to 70 °C
• Robust construction for repeated moves and reterminations

What distances and equipment are these cables compatible with?

These single-mode OS2 jumpers are suitable for long-reach connections and linkups using SFP+/SFP transceivers, media converters, and fiber NICs. Distance capability depends on equipment and wavelength; they excel at longer single-mode runs compared to multimode alternatives.

• Designed for 9/125µm single-mode infrastructure (OS2)
• Compatible with SFP/SFP+/SFP28 transceivers and optical NICs
• Distance varies by transceiver and speed — optimized for long-reach links

Who is this for: Network engineers, data center technicians, and IT teams who need compact, reliable single-mode duplex patch cords for rack-mounted equipment, server rooms, and campus backbone runs. The 4-meter length and six-pack format suit projects that require multiple identical, labeled jumpers for consistent deployments and easier cable management.
