FLYPROFiber OS2 LC-LC Duplex Singlemode Patch Cables, 3m 6-Pack — Yellow LSZH, UPC 9/125µm Low-Loss

FLYPROFiber OS2 LC-to-LC duplex singlemode patch cable pack (3m, 6 pieces) is a low-loss, flexible 9/125µm fiber jumper engineered for data-center, network and telecom links that need compact, reliable single-mode connections.

These six yellow LC–LC patch cords from FLYPROFiber are designed for high-density racks and long-reach singlemode links. Each 3-meter cable uses OS2 9/125µm fiber with UPC-polished connectors and Japan-made zirconia ferrules for precise alignment. The LSZH jacket reduces smoke and toxic emissions while the 2.0mm durable construction and 16mm minimum bend radius provide extra flexibility in tight cable runs.

How does this cable support high-density networking?

The slim LC duplex connectors and 2.0mm cable diameter save space inside patch panels and trays, making them a fit for crowded cabinets. Duplex clips and clear A/B labeling simplify pairing and reduce errors when routing transmit and receive lines.

• Duplex LC–LC terminated for compact port footprint
• Embossed A/B marks and jacket tag rings labeled 1 & 2 for quick identification
• 2.0mm jacket fits tight routing pathways and common cable managers
• Pack of six cords for multiple patching points or spares

What performance can I expect for singlemode links?

FLYPROFiber OS2 singlemode construction achieves low insertion loss and high return loss to keep optical budgets healthy across the link. UPC-polished endfaces and precision zirconia ferrules ensure consistent optical alignment for stable signal transmission.

• Insertion loss ≤ 0.3 dB per connector for minimal signal degradation
• Return loss ≥ 30 dB to limit back-reflection in singlemode systems
• 9/125µm OS2 fiber optimized for long-distance singlemode runs
• Japan-made zirconia ferrules for repeatable connector mating

Will these cables survive tight bends and varied environments?

Yes — the cords accept a 16mm minimum bend radius, which is substantially more flexible than many standard fibers and helps avoid macro-bending loss in cramped installations. The LSZH outer jacket provides a wider operating temperature range and safer smoke behavior in enclosed spaces.

• 16mm minimum bend radius reduces risk of bend-induced loss in dense racks
• Operating range from -20°C to 70°C for common indoor deployments
• Low Smoke Zero Halogen jacket for safer use in populated areas
• Removable dust caps protect ferrules during transport and installation

How easy is installation and troubleshooting with these jumpers?

FLYPROFiber designed the cables for quick, error-resistant deployment: adjustable LC clips hold duplex pairs securely, dust caps protect endfaces until mating, and obvious labeling speeds up verification. The 3-meter length is a practical middle ground for many patch-panel-to-switch paths.

• Adjustable LC-LC clips keep Tx/Rx pairs aligned and secure
• Removable dust caps prevent contamination before termination
• Clear A/B designation reduces swap errors during testing
• Six-cable pack simplifies bulk provisioning for multiple ports

Who is this for: Network engineers, data-center technicians, telecom installers and IT managers who need reliable singlemode patching in high-density cabinets and premise networks. This six-pack suits new rack builds, upgrades, or on-hand spares for service calls, offering consistent optical performance, compact LC form-factor, and safe indoor jacketing for commercial environments.
