FCD OS2 LC to LC Fiber Optic Cable 50M - Plenum Duplex 10G

In this review the FCD OS2 LC to LC 50M fiber patch cable is tested as a practical, no-surprises singlemode jumper for installations that demand 10 Gigabit links over distance. It is aimed at network engineers and IT managers who need a durable, plenum-rated duplex cable with low connector loss and consistent performance. The single biggest reason to buy is its combination of Corning 9/125 singlemode fiber and OFNP plenum jacket that makes it suitable for data center and riser runs where fire-rated cabling is required.

Key Features

• OS2 Singlemode: Provides a singlemode 9/125 Corning core that supports 10Gig signals over several kilometers with low attenuation for long, stable links.
• LC to LC Termination: Duplex LC connectors are factory-terminated with typical connector loss around 0.30 dB, helping preserve signal margin in dense networking setups.
• Plenum Rated OFNP Jacket: OFNP plenum construction allows safe installation in air-handling spaces and meets stricter fire-safety requirements.
• 2.0mm Zip-Cord Design: The 2.0mm outer diameter zip-cord style and PVC jacket make it easy to route and identify while resisting everyday handling wear.
• 10 Gigabit Support: Rated for 10Gbase-L and 10Gbase-E ranges at 1310nm and 1550nm respectively, enabling SFP/SFP+ data services and audio/video applications.

Who It's For

The cable is best for network administrators in education, corporate, healthcare, government, and finance environments who need a plenum-rated, long-reach singlemode jumper for patching between racks, switches, and SFP modules. It fits projects where 10 Gigabit performance and safety compliance are priorities.

It is less appropriate for installers who need multimode fiber, custom connector types, or ultra-flexible indoor office patch cords under 1m; those buyers should select a different fiber type or a different cable diameter suited to tight bend routing.

Pros & Cons

Pros

• Plenum OFNP jacket meets air-handling space requirements and reduces fire risk in building installations.
• Corning 9/125 OS2 fiber offers low attenuation and supports 10 Gigabit links over long distances.
• Factory-terminated LC to LC connectors with typical 0.30 dB loss provide reliable optical performance out of the box.
• Zip-cord 2.0mm construction is easy to manage and color-coded yellow for singlemode identification.

Cons

• At 2.0mm diameter and plenum jacket, the cable is stiffer than thin patch cords and may be harder to route in very tight conduits.
